July scientific gossip list： O blood attracts mosquitoes most？

People’s Daily Online, Beijing, August 1st (Zhao Zhuqing) "O-type blood attracts mosquitoes especially", "Too much beer will lead to a beer belly" and "Eating out-of-season fruits and vegetables is harmful to health" … With the arrival of midsummer, all kinds of "legends" about summer began to be "hot" on the Internet. A few days ago, the Beijing Science and Technology Journalists Editors Association and the Beijing regional website jointly released the "July Science Rumors List" to expose the true face of these rumors one by one.

1. Is the "beer belly" really drunk by drinking beer?

Myth: Many people say that beer belly is definitely related to beer, because beer is "liquid bread", and drinking too much will cause beer belly.

Truth: Beer belly is a figurative term. The real cause is unreasonable eating habits, and beer with the same weight is far less calorie-rich than bread.

The real beer belly is a lot of fat accumulated on the belly, and the accumulation of fat comes from excessive energy. Even female comrades who don’t drink beer and accumulate more body fat will have a very fat abdomen.

Li Hong, a professor-level senior engineer in the Brewing Engineering Development Department of China Food Fermentation Industry Research Institute, said: "The excess energy comes from two aspects. The first is too much energy intake, and the second is too little energy consumption. After excess energy exists in the form of fat, it is easy to accumulate in the abdomen. So, does it have anything to do with beer? It should be said that there is no direct and inevitable relationship, but what is really relevant is the way and lifestyle of consuming food. "

A study by the German Federal Institute of Nutrition Medicine shows that "beer belly" is related to male genes, just like female obesity starts from the buttocks, and most of male fat is stored in the abdomen. The researchers found that beer drinkers are not more likely to have a beer belly or even obesity than those who don’t drink beer. Although beer is not a diet drink, it is not the cause of overweight. If factors such as exercise and education are excluded, people who often drink beer will not have thicker waistlines and heavier weights than those who don’t drink or rarely drink.

2. Type O blood attracts mosquitoes most?

Myth: When summer comes, mosquito bites make many people miserable. Many rumors say that type O blood is sweet and fragrant, so type O blood is especially attractive to mosquitoes.

Truth: Mosquitoes mainly rely on carbon dioxide, heat, volatile chemicals and other factors to detect and locate targets. It can distinguish some molecules produced by human cell activities. As long as you are breathing, sweating or emitting heat, your temperature, the water vapor and carbon dioxide you release, and the chemicals in your sweat, such as acetone, octenol and lactic acid, are tempting mosquitoes to follow the trail to find you.

So is there any relationship between blood type and mosquitoes? Scientists and media from all over the world have done a lot of experiments, and the current conclusion proves that there is no direct relationship.

As for the saying that "blood is sweeter than mosquitoes", according to the current research conclusions, there is no direct connection between these two points. If you want to find the correlation from the blood test report, you may wish to pay attention to the routine examination of the physical examination report. There is an item called "eosinophils" in the column of blood test, and those who are higher in this item are better for mosquitoes.

3. Is there really a "watermelon injection"?

Rumor: A friend in Daxing told me that now melon farmers are spraying pesticides on watermelons, growing fast and selling money, and grafting on pumpkin seedlings, and they never eat them themselves! "Injection watermelon" is injected with banned food additives-sodium cyclamate and carmine! It may damage the liver and kidneys and affect children’s intellectual development! The watermelon pulp that has been injected is red and the juice is "rich".

Truth: In response to rumors, Shenzhen Inspection and Quarantine Bureau conducted a surprise inspection on six watermelon enterprises and processing plants in its jurisdiction, and none of them detected saccharin sodium, artificial color and mercurochrome (mercury bromide red). Some experts even conducted injection experiments, and the results showed that the color of watermelon pulp after injection was uneven, and because the pinhole was easy to be infected with bacteria, watermelon was perishable, which was not conducive to sales.

As for injecting sodium cyclamate and carmine, the reason is similar. According to botanical principles, plants can only absorb water and nutrients in living conditions, and they need to be organized by means of plant transportation system. However, the vascular bundles of melon seedlings are very small, and it is hard to imagine that they want to inject liquid. Even if the injection is successful, it must be absorbed and transformed by the plant itself to make it sweet. However, these two substances cannot be absorbed normally by the melon seedlings.

Moreover, after the injection, the pinhole on the watermelon is obvious, the juice will overflow from the pinhole, and the color of the pulp at the injection site will also deepen. These phenomena are very obvious, and it is easy for merchants to be seen through if they really do this.

No matter during the growth or after the harvest of watermelon, it is impossible to absorb the liquid substance by injecting it into the watermelon fruit. Only through vascular tissue can plants absorb water and nutrients and inject them into fruits forcibly, and the injected substances will accumulate in tiny tissues and destroy the tissue characteristics of watermelon pulp, which can never be like that in Weibo: red watermelon pulp and rich juice. This is also proved by experiments. No matter the size of the pinhole, the outer ring of the pinhole will begin to blacken after two or three hours of storage of the injected watermelon, which is easy to find. How can anyone do such a thankless thing if it is put out and no one cares about it?

4. Is it necessary to sweat in summer?

Rumor: "Practicing for 39 days in winter and three days in summer" is the spoken language of many middle-aged and elderly people’s sports, especially in the dog days, and middle-aged and elderly people who are sweating can be seen everywhere on the avenue and in the park. They said that many health reminders said: "It is only comfortable to sweat thoroughly, and the fitness effect can be achieved."

Truth: Experts remind that fitness should not blindly pursue sports pleasure, especially in the summer when sweating and consumption are high, bodybuilders should pay more attention to the degree of exercise to avoid excessive consumption and damage to some functions of people.

Sweat properly in summer, but you don’t need to exercise until you sweat profusely. In fact, it is easy to cause dehydration. At the same time, people’s body temperature rises obviously after summer exercise, and with the influence of high temperature weather, they are prone to heatstroke. Therefore, most people should avoid extreme exercise and anaerobic exercise, and it is best to use aerobic uniform exercise, and the heart rate should be controlled in a small exercise area, that is, about 120 times/minute. Middle-aged and elderly people should be slower, because if they exercise excessively in midsummer, sweating will lead to thick blood. Coupled with the hot weather, it is likely that they will not be healthy, but will lead to heart disease and cerebral infarction.

Exercise in the sun for a long time in summer will aggravate the disorder of water and salt metabolism in the body. Therefore, you should drink some light salt water or sports drinks before, during and after exercise, about 50 ~ 100 ml every half hour.

In addition, summer exercise is more suitable to choose morning or evening, and the location is chosen in a place with shade. The duration of exercise should not be too long, and it should be 30 minutes to 1 hour, which can be adjusted according to personal physique and exercise intensity.

5. Will the baby die if he eats salt?

Rumor: Recently, it was reported that "a mother listened to her neighbor’s advice and added salt to her porridge, but she didn’t expect to ruin her eight-month-old child’s life."

Truth: Salt is essential for everyone. For infants, less salt is the general principle.

One of the reasons why we need less salt is because of physiological limitations. The salt in the human body is mainly metabolized by the kidney, more than 90% enters the urine, and the rest is excreted through sweat. Because the development of infants’ kidneys is not complete, excessive salt intake is likely to increase the burden on the kidneys, lead to abnormal metabolism, and cause edema. Of course, it’s impossible to be so exaggerated to die immediately.

The main reason for the lack of salt is long-term consideration. The occurrence of hypertension is closely related to high-salt diet, and in order to reduce the salt intake of adults, we must start from controlling the taste of infants. Infant’s taste system is still in the developing process, and it is very sensitive to condiments. Too much salt may not only affect their eating habits in the long run, but also cause refusal to eat.

That is to say, it’s not "babies can’t eat salt within one year old", but following the general principle of less salt, it’s not necessary to add extra salt to babies, but also to keep your eyes open, pay attention to the formula table of complementary food, and rationally allocate baby’s recipes.

6. margarine equals trans fatty acids?

Myth: Margarine is mainly extracted from edible oils and fats, so margarine contains more oils and fats, especially trans fatty acids. Eating a lot of trans fatty acids will affect people’s memory, and for teenagers, it will affect the development of the central nervous system. Long-term excessive accumulation of trans fatty acids can also induce serious diseases such as asthma, tumor and diabetes.

Truth: The statement that "trans fatty acids have health risks" has been widely circulated. Recently, China Food Rumor Alliance and China Baked Food and Sugar Products Industry Association publicly refuted this rumor. The Food Rumor Alliance stated that raw materials of baked goods such as margarine and hydrogenated vegetable oil are not equal to trans fatty acids, and the argument that trans fatty acids cause obesity and diabetes is still inconclusive.

According to Zhu Nianlin, chairman of China Baked Food and Sugar Products Industry Association, trans fatty acids have always been regarded as "time bombs on the table", and raw materials in baked goods-margarine, hydrogenated vegetable oil, non-dairy creamer, shortening and cocoa butter substitute are often labeled as trans fatty acids, which has caused adverse effects on the industry.

Professor Cao Yanping from the College of Food Science of Beijing Technology and Business University said that with the development of technology, the trans fatty acid content in oil has dropped to a very low level. If consumers need it, they can completely remove trans fatty acids, but it will affect the taste of food.

According to Kai Zhong, deputy director of Kexin Food and Nutrition Information Exchange Center, in addition to processed foods, trans fats are widely found in natural foods such as beef, mutton, fat and milk. According to the report of China Residents’ Dietary Intake Level of Trans Fatty Acids and Its Risk Assessment by the National Food Safety Risk Assessment Center in 2013, the average daily intake of trans fats in China is 0.39 grams, and the energy supply ratio is 0.16%, which is far lower than the recommended value of the World Health Organization (less than 1%).

However, in order to control the intake of trans fatty acids, the Food Rumor Alliance suggests that consumers should pay more attention to the nutrient list on the label when buying packaged foods, and they can choose foods that do not contain trans fatty acids or have low content, especially those for infants and young children. In addition, it is necessary to control the amount of vegetable oil used in cooking, not to consume a large amount of animal fat to avoid trans fatty acids, and to avoid excessive oil temperature and repeated frying.

7. Do soy products induce breast cancer?

Myth: The disorder of breast structure caused by the absolute or relative increase of estrogen level and the decrease of progesterone level can induce lobular hyperplasia of breast, while the phytochemicals contained in soybean and bean products, such as soybean isoflavones, are known as "phytoestrogens", so bean products will aggravate mammary hyperplasia and even induce breast cancer.

Truth: Soybean isoflavone in soybean is a phytoestrogen, and many people worry that it will induce breast cancer.

In fact, phytoestrogens are different from human estrogens. It is found that phytoestrogens play a two-way role in regulating estrogen levels in women.

Studies have shown that eating soy products will not only cause breast cancer, but also reduce its risk.

8. Eating out-of-season fruits and vegetables is harmful to health?

Myth: A post about "out-of-season fruit and vegetable hazards" is widely circulated on the Internet. This post states categorically that the planting process of out-of-season fruits and vegetables is not as safe as it seems. In order to achieve high and stable yield, farmers often overuse highly toxic pesticides and ripening hormones.

Truth: Many people will say that out-of-season fruits are poisonous and inedible because they use a lot of chemicals such as pesticides. In fact, even seasonal fruits will use pesticides in the planting process. It is normal to have pesticide residues, and "existence" does not mean "exceeding the standard" or "excessive", nor does it mean that eating out-of-season fruits will do harm to the body. Moreover, as long as the general fruit is planted in a standardized way, the pesticide residue does not exceed the standard, and normal consumption will not cause harm to human health.

There is also a saying that out-of-season fruits need to be "promoted" by plant hormones, which will make people precocious. In fact, whether it is out-of-season fruit or in-season fruit, a certain amount of plant growth regulators, that is, plant hormones, are used in the modern planting process. In addition, all fruits naturally contain a certain amount of phytohormones. However, the efficacy of plant hormones is generally very low, and they are different from the molecular structure and mechanism of action of human hormones, and will not have adverse effects on the human body. It is only unfounded to worry about precocious human nature. In addition, plant hormones have strong self-limitation, and farmers will not add more in the normal planting process, otherwise it will be counterproductive.

There is another worry about out-of-season fruits, that is, they are considered to have poor nutrition.

The nutritional value of out-of-season fruits may indeed be different from that of in-season fruits. However, these differences do not mean that they are not nutritious, let alone harmful. Considering that in the cold winter, if there is no fruit to eat, human health may be more affected. From the perspective of nutrition supply, eating fruit is much better than not eating. For example, eating grapes out of season in winter is far better than "no grapes to eat".

Generally speaking, there is nothing wrong with out-of-season fruits and vegetables. Compared with winter without fruits and vegetables, out-of-season fruits are still very helpful for people to obtain and supplement nutrients, especially vitamins and minerals.

9. "Don’t eat after noon" helps to lose weight?

Myth: "Don’t eat after noon" probably means that you don’t eat after noon (from 11: 00 noon to 1: 00 pm) until dawn the next day. In the minds of many dieters, "no food after noon" is regarded as "a good way to lose weight". Some people even regard it as a "secret method of health preservation" and insist on it for many years.

Truth: If people are on an empty stomach for a long time, then the body will have some abnormal reactions-the contents of two hormones that regulate weight will deviate greatly from the normal value:

Brain-gut peptides that can increase appetite, stimulate hunger, accelerate gastric emptying and gastric acid secretion will increase rapidly; Leptin, which can reduce appetite and inhibit the synthesis of fat cells, will be greatly reduced. If so, people will not lose weight after lunch, but will gain weight more easily.

Eating the right dinner is more helpful to health than not eating it. It is best to have dinner between 5: 00 and 7: 00, and try to keep it regular; Dinner should be light, and you can eat some lean meat or eggs with short muscle fiber and easy digestion. Eat more vegetables and coarse grains.

Compared with the ancients, modern people have a large amount of activities at night, and often go to bed in the early hours of the morning. If they don’t eat dinner or even stop eating, they will lack energy, and there is gastric acid in the human stomach. If they don’t eat for a long time, it may cause gastric acid to damage the gastric mucosa, and diseases such as ulcers will appear over time. If the ulcer is not found in time, it is likely that more serious diseases such as gastrointestinal bleeding and ulcer perforation will occur.

"No food after noon" is not suitable for everyone. Only by grasping the rhythm and habits of eating carefully can we realize our pursuit of good figure under the premise of health. Eat after noon, and eat with high quality. This is the correct way to keep in good health.

Is about to turn into a super typhoon! Typhoon ＂Du Surui＂ struck these places to be alert to extreme precipitation.

　　China Weather Network News This morning (July 24th), the No.5 typhoon "Du Surui" this year has been strengthened to a strong typhoon level, and it will become a super typhoon tonight, and it will probably land in Fujian or Guangdong as a typhoon or strong typhoon level later, which may become the strongest typhoon landing in China this year. Affected by this, Taiwan Province, Fujian, Zhejiang and other places have experienced strong winds and heavy rains, and some areas may break the precipitation record in the same period. What are the characteristics of Du Surui? What other changes have taken place in its path trend? When does it enter the core period of influence?

　　Typhoon "Du Surui" strengthened rapidly in two days, and the strongest typhoon could reach super typhoon level.

　　At 08: 00 on July 21, the No.5 typhoon "Du Surui" was generated this year, and it has been moving slowly in the east of the Philippines since then. In recent two days, "Du Surui" has strengthened rapidly, strengthening to a strong tropical storm level at 05: 00 on the 23rd, a typhoon level at 17: 00 on the 23rd, and a strong typhoon level at 24: 08.

　　"Du Surui" is huge and the cloud system is complete. (Photo/National Satellite Meteorological Center)

　　"Typhoon ‘ Du Surui ’ It has the characteristics of strong strength, strong wind and rain and wide influence. " According to Zhang Juan, a meteorologist of China Weather Network, from the cloud image, the typhoon eye of Du Surui is clear and complete at present; The southwest monsoon on the south side continuously gives water vapor and energy support, and the wispy high-level outflow cloud system can be clearly seen on the east side, which means that the pumping effect of high-altitude outflow is also strong; Coupled with the current high sea temperature conditions, these are conducive to the enhancement of typhoon intensity. It is estimated that the peak intensity of Du Surui can reach the super typhoon level.

　　There are still variables in the trend of Du Surui’s high probability landing in Fujian or Guangdong coastal areas.

　　At 14: 00 this afternoon, the center of Typhoon Du Surui was about 900 kilometers southeast of Taiwan Province’s Eguanbi. It is estimated that it will move to the northwest at a speed of 10-15 kilometers per hour, and its intensity will continue to strengthen. The strongest typhoon level can reach (the strongest wind force near the center is 16-17), and it will gradually approach the southern coast of Taiwan Province Island, possibly passing through or landing on the southwest coast of Taiwan Province, then approaching the coast of Fujian, landing on the coast of Fujian in the morning of the 28th, and moving to the north-west direction after landing.

　　Zhang Juan reminded that there are still variables in the path trend of "Du Surui", and the specific direction depends mainly on the "face" of the subtropical high. If the subtropical high is stronger, the weight of the typhoon going west will increase, and there is the possibility of landing in eastern Guangdong; If the subtropical high weakens, the typhoon track will be northward, and the possibility of passing by or landing in Taiwan Province will increase. "Du Surui" may avoid Luzon Island in the Philippines and Taiwan Province Island in China, and become a first-hand typhoon landing in Fujian or Guangdong, which will have a greater impact on the wind and rain, and the change of landing location will affect the change of the core rainfall area. The public should pay close attention to the typhoon trends and trends and make preparations for typhoon defense in advance.

　　Taiwan Province, Fujian, Zhejiang and other places with strong winds and heavy rains may break the precipitation record in the same period.

　　Under the influence of Du Surui, it is estimated that there will be 9-11 winds and 12-14 gusts in bashi channel, the southeast of Taiwan Province, the Taiwan Province Strait, the southern coast of Taiwan Province Island and the south-central coast of Fujian from 24th to 29th. The winds in the nearby sea or areas where Du Surui Center passes are 12-16, and the gusts can reach 17 or above.

　　"The impact of typhoon on China’s rainfall will gradually appear from tomorrow." Zhang Juan said that from the night of the 25th, the rainfall in southeastern Taiwan Province will gradually increase; From 27th to 29th, it is the main period affected by typhoon. Among them, there will be heavy rain or even heavy rain in most parts of Taiwan Province on the 27th, and there may be heavy rain or heavy rain in Fujian and southern Zhejiang on the 28th, and some areas may break the precipitation record in the same period.

qxtx

　　Typhoon "Du Surui" struck hard. Keep this scientific defense guide.

　　Typhoon Du Surui’s peak intensity can reach super typhoon. Whether it lands in Taiwan Province, Fujian or Guangdong, it will bring strong wind and rain, which will seriously affect the daily life of local people. So, what preparations do residents need to make before the typhoon comes? How to avoid danger when a typhoon comes?

　　Before the typhoon comes, residents should listen, watch or check the typhoon warning information in time to understand the government’s typhoon prevention measures; Then close the doors and windows, and turn off computers, televisions and other electronic equipment; Reserve food and water, and prepare emergency items such as mobile power supply and flashlight; Check whether the circuit, fire, gas and other facilities are safe; Residents living in all kinds of dilapidated houses, factories and sheds should be moved to safety in time; If you are already in a solid house, you can stick a "meter" pattern on the window glass with adhesive tape to prevent the window glass from breaking.

　　When the typhoon comes, you should continue to pay attention to the dynamic information of the typhoon. It is best not to go out. If you are outside, don’t take shelter from the wind and rain near temporary buildings, billboards, iron towers and trees. If you drive, you should immediately drive to the underground parking lot or shelter; If you are in a tent, you should immediately put away your tent and take shelter from the wind in a solid house; If you are on the water, you should immediately go ashore to take shelter from the wind and rain.

In-depth study and understanding of General Secretary Supreme Leader’s new ideas, new viewpoints and new conclusions on cultural construction (in-depth study and implementation of Supreme Leader’s Soc

　　synopsis

　　Culture is an important force for national survival and development. To shoulder the new cultural mission and build the modern civilization of the Chinese nation, we must thoroughly study and understand the new ideas, new viewpoints and new conclusions of the Supreme Leader General Secretary on cultural construction, and implement them in all aspects of the whole process of cultural construction.

　　Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has put cultural construction in an important position in the overall work in the practice of leading the party and the people to promote the governance of the country, continuously deepened the understanding of the regularity of cultural construction, and put forward a series of new ideas, new viewpoints and new conclusions, which has promoted the historical achievements and changes in China’s cultural construction in radical reform and innovation, and provided strong positive energy for upholding and developing Socialism with Chinese characteristics in the new era and creating a new situation in the development of the cause of the party and the country. General Secretary of the Supreme Leader pointed out at the symposium on cultural inheritance and development: "It is our new cultural mission in the new era to continue to promote cultural prosperity, build a cultural power and build a modern civilization of the Chinese nation at a new starting point." To shoulder the new cultural mission and build the modern civilization of the Chinese nation, we must thoroughly study and understand the new ideas, new viewpoints and new conclusions of the Supreme Leader General Secretary on cultural construction, and implement them in all aspects of the whole process of cultural construction. Among them, we must grasp the following important aspects in depth.

　　Adhere to "two combinations" and consolidate cultural subjectivity

　　General Secretary of the Supreme Leader pointed out: "It is the only way to open up and develop Socialism with Chinese characteristics on the profound foundation of Chinese civilization for more than 5,000 years, and to combine the basic principles of Marxism with the concrete reality of China and the excellent traditional Chinese culture. This is our regular understanding in exploring the road to Socialism with Chinese characteristics and the greatest magic weapon for our success. " "Insist on combining the basic principles of Marxism with the concrete reality of China and the excellent traditional Chinese culture" is a major conclusion put forward by the Supreme Leader General Secretary in his important speech at the celebration of the centenary of the founding of the Communist Party of China (CPC). At the symposium on cultural inheritance and development, General Secretary of the Supreme Leader profoundly explained the great significance and important connotation of combining the basic principles of Marxism with Chinese excellent traditional culture from five aspects, emphasizing "‘ The second combination ’ It is another ideological emancipation that allows us to make full use of the valuable resources of Chinese excellent traditional culture in a broader cultural space and explore future-oriented theoretical and institutional innovations. " The "second combination" is our party’s profound summary of the historical experience of the modernization of Marxism in China, and a profound grasp of the law of the development of Chinese civilization, indicating that our party’s understanding of China’s road, theory and system has reached a new height, indicating that our party’s historical self-confidence and cultural self-confidence have reached a new height.It shows that our party’s consciousness of promoting cultural innovation in inheriting Chinese excellent traditional culture has reached a new height.

　　Since the 18th National Congress of the Communist Party of China, our Party has persisted in taking Marxism as the guidance, emancipating the mind, seeking truth from facts, keeping pace with the times, seeking truth and being pragmatic, constantly answering China’s questions, the questions of the world, the questions of the people and the questions of the times scientifically, making correct answers that conform to the reality of China and the requirements of the times, drawing scientific understanding that conforms to objective laws, forming theoretical achievements that keep pace with the times, and better guiding China’s practice; Our party insists on making the past serve the present, bringing forth the new, upholding the integrity and respecting the past and not restoring the past, linking the essence of Marxism with the essence of Chinese excellent traditional culture, and integrating it with the common values that the people are unaware of every day, endowing Chinese civilization with modern strength by Chinese modernization, endowing Chinese modernization with profound details, promoting the creative transformation and innovative development of Chinese excellent traditional culture, and achieving a series of major achievements and important experiences. Chinese excellent traditional culture and Chinese modern civilization have achieved unprecedented brand-new results. The "two combinations" consolidated the cultural subjectivity of the Chinese nation, and the creation of the Supreme Leader’s New Era Socialism with Chinese characteristics Thought is the most powerful embodiment of this cultural subjectivity.

　　Strengthen cultural self-confidence and enhance the spiritual strength of the great rejuvenation of the Chinese nation.

　　Our party has always attached importance to the strategic significance of cultural construction in realizing the great rejuvenation of the Chinese nation. Since the 18th National Congress of the Communist Party of China, the General Secretary of the Supreme Leader has scientifically explained the essence of culture based on the unprecedented great changes in the world and the overall situation of the great rejuvenation strategy of the Chinese nation, put forward that cultural self-confidence is "more basic, broader and deeper self-confidence", profoundly discussed the essence of Socialism with Chinese characteristics culture and its significance for realizing the great rejuvenation of the Chinese nation, and pointed out the new historical orientation and new cultural mission of cultural construction in the new era.

　　General Secretary of the Supreme Leader pointed out: "Culture is the soul of a country and a nation", "To strengthen Socialism with Chinese characteristics’s road confidence, theoretical confidence and institutional confidence, in the final analysis, it is necessary to strengthen cultural self-confidence", "Socialism with Chinese characteristics culture accumulates the deepest spiritual pursuit of the Chinese nation, represents the unique spiritual identity of the Chinese nation, and is a powerful spiritual force for Chinese people to March forward triumphantly", "Realizing the Chinese dream is the development process of material civilization and spiritual civilization fly with me" and "Without the prosperity of Chinese culture, there would be no Chinese. General Secretary Supreme Leader’s important exposition enriches Socialism with Chinese characteristics’s cultural development concept, broadens the road of Socialism with Chinese characteristics’s cultural development, and deepens the understanding of the law of Socialism with Chinese characteristics’s cultural construction, which is a concentrated expression of our party’s strong cultural responsibility and high cultural self-confidence.

　　Adhere to the fundamental system of Marxism’s guiding position in the ideological field and consolidate the common ideological foundation of the United struggle of the whole party and the people of the whole country.

　　Marxism is the fundamental guiding ideology of building the party and building the country, rejuvenating the party and rejuvenating the country, and is the soul and banner of our party. General Secretary of the Supreme Leader pointed out: "Marxism is the root of the towering tree of the continuous development of the cause of our party and people, and it is the source of the long river of Wan Li where our party and people keep forging ahead." "On the fundamental issue of adhering to the guidance of Marxism, we must be firm and unshakable at any time and under any circumstances." History and practice show that the fundamental system of adhering to the guiding position of Marxism in the ideological field is an important support of Socialism with Chinese characteristics’s system, an essential requirement of upholding and strengthening the overall leadership of the Party, and a powerful guarantee for developing advanced socialist culture.

　　System construction is overall, stable and long-term. To ensure that the guiding position of Marxism is reflected in the various undertakings of the party and the state, and to play the leading role of Marxism in social ideology requires strong institutional support and reliable institutional guarantee. The Decision of the Central Committee of the Communist Party of China on Upholding and Perfecting the Socialism with Chinese characteristics System and Promoting the Modernization of the National Governance System and Governance Capacity, which was deliberated and adopted by the Fourth Plenary Session of the 19th CPC Central Committee, emphasized the fundamental system of upholding the guiding position of Marxism in the ideological field, and made a series of major arrangements, clearly put forward and improved the work system of arming the whole party and educating the people with the Party’s innovative theory, improved the learning system at all levels such as the theoretical learning center group of the Party committee (party group), established the system and mechanism of educating people in a full, full and all-round way, and implemented the ideology. This is of great significance for building a socialist ideology with strong cohesion and leading power and consolidating the common ideological foundation of the United struggle of the whole party and the people of the whole country.

　　Adhere to and strengthen the party’s overall leadership over ideological work, and firmly grasp the leadership, management and discourse power of ideological work.

　　Ideological work is an important aspect of cultural construction. Whether ideological work can be done well is related to the future and destiny of the party, the long-term stability of the country, national cohesion and centripetal force. Since the 18th National Congress of the Communist Party of China, the General Secretary of the Supreme Leader has placed ideological work at the height of the overall strategic situation, emphasized that "ideological work is the work of building the heart for the country and the soul for the nation", put forward a series of new ideas, new viewpoints and new theories, made a series of major arrangements, made efforts in various ways to solve the outstanding problems, and adopted various methods to effectively reverse the passive situation that once appeared in the ideological field.

　　General Secretary of the Supreme Leader asked the whole Party to fully understand the complexity and long-term nature of ideological struggle, enhance the position consciousness, strengthen the position construction, and firmly grasp the leadership, management and discourse power of ideological work. The General Secretary of the Supreme Leader profoundly pointed out: "Propaganda and ideological positions, if we don’t occupy them, others will occupy them." General Secretary of the Supreme Leader stressed: "All propaganda and ideological departments and units, party member and cadres on the propaganda and ideological front must adhere to the principle of party spirit in a clear-cut manner." "The core of adhering to party spirit is to adhere to the correct political direction, stand firm in political stance, firmly publicize the party’s theory, line, principles and policies, firmly publicize the major work arrangements of the central government, firmly publicize the central government’s major analysis and judgment on the situation, resolutely maintain a high degree of consistency with the CPC Central Committee, and resolutely safeguard the central authority." Wall-riding school ’ And ‘ See the wind school ’ You can’t cherish feathers. Comrades on the propaganda and ideological front should fulfill their sacred duties and glorious missions, and actively participate in the front line of propaganda and ideological struggle with the attitude of fighting and the responsibility of soldiers. " In the decade of the new era, under the strong leadership of the CPC Central Committee with the Supreme Leader as the core, the ideological situation in China has undergone an overall and fundamental change, and the cultural self-confidence of the whole party and the people of all ethnic groups has been significantly enhanced.The cohesion and centripetal force of the whole society have greatly improved, providing a strong ideological guarantee and strong spiritual strength for the new era to create a new situation in the cause of the party and the state.

　　Cultivate and practice socialist core values and improve the ideological and moral level of the whole nation.

　　General Secretary of the Supreme Leader pointed out: "For a nation and a country, the most lasting and deepest strength is the core values recognized by the whole society. Core values bear the spiritual pursuit of a nation and a country, and embody a value standard for judging the merits of a society. Cultivating and carrying forward core values and effectively integrating social consciousness are important ways for the normal operation of social systems and the effective maintenance of social order, and are also important aspects of national governance system and governance capacity. History and reality show that core values are an important stabilizer for a country, and whether they can be constructed with strong appeal is related to social harmony. To strengthen cultural self-confidence, carry forward the spirit of China, highlight China’s values and unite China’s strength, we must vigorously cultivate and practice socialist core values, take cultivating and carrying forward socialist core values as a basic project to gather spirits and strengthen the foundation, constantly consolidate the ideological and moral foundation of Socialism with Chinese characteristics and improve the ideological and moral level of the whole nation.

　　General Secretary of the Supreme Leader pointed out: "Chinese civilization stretches for thousands of years and has its unique value system." "We advocate and carry forward socialist core values, and we must draw rich nutrition from them, otherwise it will not have vitality and influence." This profoundly enlightens us that the cultivation and promotion of socialist core values must be based on Chinese excellent traditional culture. The firm core values have their inherent roots. Abandoning tradition and losing the roots is tantamount to cutting off one’s spiritual lifeline. In the new era and new journey, in order to build the modern civilization of the Chinese nation, we should cultivate and practice the socialist core values, seriously absorb the ideological essence and moral essence of Chinese excellent traditional culture, deeply explore and expound the times values of Chinese excellent traditional culture, such as caring, attaching importance to the people, keeping honesty, worshiping justice, respecting harmony and seeking harmony, and inheriting and carrying forward them in light of the new times conditions, so as to make them an important source of cultivating socialist core values.

Hubei： Ecological Priority, Green Development, Firmly Stand Up the ＂Waist of the Yangtze River＂

　　The finless porpoise swims in the old course of the Yangtze River in Swan Island, Hubei Province. Photo by Niu Yibin

　　On the sparkling Wuhan section of the Yangtze River, finless porpoises are in groups of three or five, chasing for food and swimming in the river in early spring. The finless porpoise has high requirements on the water environment and is known as the "giant panda in the water". After the implementation of the great protection strategy of the Yangtze River, with the improvement of water quality and the increase of fish, the once rare finless porpoise has gradually increased.

　　"The Yangtze River Economic Belt should embark on a new path of ecological priority and green development." Four years ago, General Secretary of the Supreme Leader gave directions and drew a blueprint for the development of the Yangtze River Economic Belt under the new situation in Hubei.

　　Sitting on the longest runoff mileage of the Yangtze River trunk line, Hubei is called the "waist of the Yangtze River" and shoulders the important mission of ensuring that "one reservoir of clear water is sent to the north and one reservoir of Qing Jiang water flows to the east". Jingchu earth keeps in mind the general secretary’s earnest entrustment, makes great efforts to further promote the high-quality development of the Yangtze River Economic Belt, and writes Hubei answer sheet.

　　Based on ecological protection, the face has taken on a new look.

　　Wuhan Hongshan River Beach starts from Baishazhou Bridge in the west and ends at Yangsigang Bridge in the east, with a total length of 3.12 kilometers, which is the "final work" of the river beach construction in the central city of Wuhan.

　　"The river beach here is so beautiful!" Ms. Zhang, who lives in Baishazhou, is playing in the park with her 9-year-old daughter. "It used to be a wasteland, but now it has a new look, and everyone says yes."

　　After years of transformation, Wuhan Jiangtan has changed from a flood control beach to a baili gallery. The quiet Hankou River Beach, the romantic and warm Hongshan River Beach, the simple and simple Wuchang River Beach, the winding Hanyang River Beach and the picturesque Qingshan River Beach have become the ecological waterfront paradise of Jiangcheng people.

　　Looking back more than 600 kilometers to the upper reaches of the Yangtze River, the same gratifying changes also took place in Yichang. In spring, the warm sun spreads all over the earth, overlooking the Yangtze River Bridge in Wujiagang, Yichang. The vegetation on both sides is lush, the trees and flowers are scattered, and the boats on the green river are busy. Under the North Shore Bridge, the Yichang Yangtze River shoreline renovation and restoration project is about to open to the public. After the completion of the project, the Yangtze River coastline will add new beauty — — Yichang Dongdaemun Ecological Corridor.

　　Behind the "green clothes" on the coastline of the Yangtze River, it is inseparable from the all-out cracking of "chemical encircling the river" and the thunder rectification of illegal docks.

　　On April 19, 2022, it was photographed on the coastline of the Yangtze River, 8 kilometers away from Xiaoting District, Yichang City, Hubei Province. After the completion, the revetment along the river in Xiaoting District was picturesque. Photo courtesy of Propaganda Department of Yichang Municipal Committee

　　In 2017, Yichang City took the lead in starting the customs clearance, modification, relocation and transfer of 134 chemical enterprises within 1 km along the Yangtze River. Hubei Xingfa Group, which is good at fine phosphorus chemical industry, resolutely started the relocation of 70,000 tons of glyphosate and glycine plant in Linjiang Park. In the process of relocation, it implemented transformation and upgrading, and cultivated electronic chemicals and new materials from silicone. The economic benefits increased instead of falling.

　　At the port of Libu, Jingzhou, it is the peak period of port freight, and several cranes are unloading sand and gravel. The blue fully enclosed belt conveyor corridor, like two tentacles, extends from the storage yard to the river bank, realizing that "sand and gravel don’t fall to the ground, and sand can’t be transported". This "air transportation corridor" can not only collect sand and gravel, but also receive ship garbage.

　　Just a few years ago, there were 40 gravel docks and more than 20 building materials enterprises along the coastline where Libo Port was located. In order to solve the problem of small, scattered and chaotic gravel docks, Jingzhou City has built a gravel collection center, which makes "a sunny day covered with dust and a rainy day covered with mud" completely a thing of the past.

　　At present, the Jingzhou section of the Yangtze River, which is 483 kilometers long, is full of beautiful scenery. The ecological green corridor meanders along the river, and it is "beaded into a chain" with the Wenchuang Garden, Wanshou Park and Yangtze River Bridge at the ocean pier, showing "the Yangtze River is thousands of miles long and the beauty is in Jingjiang".

　　"Man and water struggle" has become "man and water depend on each other", and the change of the word difference shows the beauty of the Yangtze River after ecological improvement.

　　Taking the top ten landmark "campaigns" of the Great Protection of the Yangtze River as the starting point, the trunk line of the Yangtze River in Hubei Province banned 1211 illegal docks, vacated 149.8 kilometers of coastline, and restored 8.56 million square meters of ecology; By the end of last year, 5,186 of the 12,480 sewage outlets in Hubei section of the Yangtze River had been rectified, and the water quality in Hubei section of the main stream of the Yangtze River had been stable at Class II standard for two consecutive years. A beautiful picture of the Yangtze River is slowly unfolding.

　　Green development is the way to promote modernization

　　Luoshan Town, honghu city is bordered by the Yangtze River in the south and the Baili Honghu Lake in the north. The local people have made the lake their home and fishing for generations, and Yu Zhimu is one of the millions of fishermen in Honghu Lake.

　　Since 1996, Yu Zhimin has covered more than 2,000 mu of water in Honghu Lake area for purse seine farming. Under the strategy of "protecting the Yangtze River together and not developing it", Yu Zhimin, who has dealt with "fishing" all his life, bid farewell to the stormy water life with the fishermen in the same village and moved from the lake to the shore to continue raising crabs. Today, Honghu base, an old fisherman in charge, has become a demonstration base for localized cultivation of crab fry in Hubei Province.

　　Not being unemployed when landing, all the 31,952 fishermen who need to change jobs have completed their jobs and taken up "new rice bowls".

　　Driven by the transformation and upgrading, the city has also ushered in great changes.

　　Huangshi, which is prosperous because of mines, is a traditional old industrial base that relies on resources. It has long relied on steel, coal and non-ferrous metals to support the industrial structure. Nowadays, the local government has inserted the wings of "technological transformation of 100 enterprises" to legislate for mine restoration, and "whoever develops will protect and whoever destroys will govern", forcing mining rights holders to implement ecological restoration and let old industrial bases open new branches and sprout.

　　The former location of Daye Iron Mine has now been transformed into a 4A-level tourist attraction Huangshi National Mine Park, and it has been listed as a "National Industrial Heritage Tourism Base", receiving more than 300,000 tourists every year.

　　The conversion of old and new kinetic energy is accelerated, and "low carbon" has become a new trend of green life.

　　Early in the morning, Li Ruyin carried a hoe and took several fellow villagers to the mountains to weed and protect bamboo forests. He is not only a villager in Jinkeng Village, Yanxia Township, Tongshan County, Xianning City, but also the "Lin Chang" of Nanzhu Base. "Can’t rest a day! I want to protect my ‘ Cash cow ’ 。” Li Ruyin said with a smile, "It is not a small sum to earn 50 yuan per mu a year. With bamboo, my annual income has doubled. "

　　The "cash cow" in Li Ruyin’s mouth is a 3,000-mu bamboo forest planted in barren hills, which is part of the carbon sink project of bamboo afforestation in Tongshan County. "Relying on bamboo forests to absorb carbon and spit oxygen, this project can absorb 6,500 tons of carbon dioxide every year. Those enterprises whose carbon emissions exceed the standard can purchase our emission reductions through Hubei Carbon Emissions Trading Center. " Li Ruhuo, one of the project investors and chairman of Tongshan Ruhuo Agricultural Science and Technology Development Co., Ltd. said.

　　A small bamboo, one end is connected with energy conservation and emission reduction, and the other end is connected with rural revitalization. Tongshan people like Li Ruyin are happy to "sell ‘ Carbon ’ Weng ". Today, there are more than 400,000 mu of bamboo carbon sequestration projects in Tongshan County, which has increased the income of more than 30,000 farmers and created a new way to get rich.

　　By the end of December 2021, the carbon market quota in Hubei had reached 365 million tons, with a total turnover of 8.651 billion yuan.

　　Scientific and technological innovation as the source to maintain vitality forever

　　At 9 o’clock in the morning of March 29th, with a loud whistle, the pure electric tourist passenger ship with the largest electricity load in the world — — "Three Gorges on the Yangtze River No.1" made its maiden voyage at Zigui Xingang Wharf in Yichang City.

　　Compared with the traditional power cruise ship, "Yangtze Three Gorges 1" is driven by clean hydropower, which can replace about 530 tons of fuel oil every year and reduce harmful gas emissions by more than 1,600 tons. After it is put into operation, it will provide new experiences for tourists and serve the green and high-quality development of the Yangtze River Economic Belt.

　　On April 8, the container port area of Wuhan Yangluo Port was even more magnificent in the afterglow of the sunset. Foreign trade containers equipped with masks, non-woven fabrics and other medical supplies will sail directly to Japan from here.

　　Thanks to the technical upgrading of the system and the integrated operation of the first, second and third phases of the port area, the annual container throughput of Yangluo Port has increased from 760,000 TEUs in 2013 to 2.48 million TEUs last year. According to statistics, the average waiting time of ships in Yangluo Port has been reduced by 12 hours, the working efficiency of the wharf has been improved by 30%, and the golden waterway has truly achieved golden benefits.

　　At present, relying on Yangluo Port, Hubei connects the "Belt and Road" with the Yangtze River Economic Belt by multi-channel multimodal transport, and builds a Wuhan port-type national logistics hub that connects things, radiates the whole country and connects the international community. In the first quarter of this year, the shipment volume of China-Europe train (Changjiang) increased by 60% compared with the same period of last year. By the end of the 14th Five-Year Plan, the port cargo throughput in Hubei Province is expected to reach 250 million tons, and the container throughput will strive to reach 5 million TEUs.

　　On the bank of the Yangtze River, a number of strategic emerging enterprises are gestating and growing, and trillions of industrial clusters such as "optical core screen end network", big health and automobile manufacturing are accelerating.

　　Wuhan East Lake High-tech Zone is full of innovation. This is the first batch of national high-tech zones and the Wuhan area of China (Hubei) Pilot Free Trade Zone, and it has been approved as a national optoelectronic information industry base, a national bio-industry base and a national storage base, also known as "China Optical Valley".

　　At present, Hubei leads the development of emerging industries with innovation drive, and accelerates the establishment of Wuhan’s nationally influential science and technology innovation center and East Lake comprehensive national science center; There are 30 national key laboratories in the province, ranking fourth in the country in total, and there are nearly 15,000 high-tech enterprises … …

　　The Yangtze River is long and the clear water is full; The sound of entrustment is inspiring. Jingchu Land is faithfully implementing the decision-making arrangements of the CPC Central Committee on the development of the Yangtze River Economic Belt, maintaining historical patience and strategic determination, carrying out a blueprint to the end, and writing a new chapter in Hubei’s high-quality development.

How can radioactive nuclear waste discharged from nuclear power plants be safely recycled？

Spent fuel pool for storing spent fuel.

In a thermal power plant, a pile of coal is burned, leaving cinders. In nuclear power plants, spent fuel is discharged after slow fission reaction of nuclear fuel.

Just like a thermal power plant needs to keep adding coal, when the nuclear fuel cannot maintain a certain power, it needs to be replaced. This kind of nuclear fuel discharged from the reactor is called spent fuel. But "lack" does not mean that it is useless. Unlike the cinder left after burning coal, there are still a lot of treasures in the spent fuel. By extracting up to 96% of unburned uranium and newly generated nuclear fuel, the fuel elements needed for power generation in nuclear power plants can be rebuilt.

For China, which is about to usher in the rapid growth of nuclear power, this way of recycling uranium resources will largely solve the thirst for "nuclear fuel". According to the estimation of the International Atomic Energy Agency (IAEA), China has 1.2-1.7 million tons of potential uranium resources, and the proven reserves of uranium resources are about 170,000 tons. With the increase of nuclear power units, China’s demand for uranium resources is increasing. Statistics from the Geology and Minerals Division of CNNC show that by 2020, China is expected to have a shortage of natural uranium of up to 2,600 tons, and by 2030, this figure will climb to 10,900 tons. For the whole world, natural uranium is also in short supply.

Spent fuel reprocessing is an extremely critical link in the nuclear fuel cycle, whether from the perspective of improving the utilization rate of uranium resources, ensuring the long-term development of nuclear energy or reducing nuclear waste. However, in the face of huge demand for nuclear energy development, China’s reprocessing capacity is in urgent need of upgrading.

Extracting "Uranium" from Spent Fuel

According to the different radioactivity, nuclear waste is divided into high-level radioactive waste and medium-low radioactive waste. Among them, the spent fuel is highly radioactive, and the work clothes, gloves, abandoned and retired instruments and equipment used in nuclear power plants belong to low-level radioactive waste.

China has developed mature disposal technology for low-level radioactive waste. Both solid nuclear waste and liquid nuclear waste are solidified first, and then put into a 200-liter stainless steel barrel and placed in a near-surface repository. At present, China has built two low-level radioactive waste disposal sites: the northwest disposal site in Yumen, Gansu Province and the south China disposal site in Beilong, Guangdong Province.

The disposal of high-level radioactive waste is a worldwide problem.

A million-kilowatt thermal power plant burns about 3.3 million tons of coal every year, but a nuclear power plant with the same capacity only uses 30 tons of nuclear fuel a year, and its weight does not change much after it becomes spent fuel. Take the million-kilowatt PWR nuclear power plant as an example, which produces 25-30 tons of spent nuclear fuel every year.

Many radioactive elements in spent fuel have a half-life of tens of thousands of years, ranging from about 2.1 million years to nearly 500 years. Spent fuel will be temporarily stored in the special boron pool of the nuclear power plant before being sent to the repository.

At present, there are two ways of spent fuel in the world: one is the "one-pass" open nuclear fuel cycle represented by the United States, and the spent fuel is sent to deep geological strata for disposal or long-term storage as waste after cooling and packaging; In the closed cycle adopted by Britain, France and other countries, spent fuel is stored in the spent fuel pool of nuclear power plants for 5-8 years and then transported to the reprocessing plant for reprocessing. In the post-treatment, the spent fuel is cut into small pieces, dissolved in acid, and useful uranium and plutonium are extracted and reused as fuel. The remaining waste liquid is given to a glass curing plant for curing, then put into a special waste tank and transported to a permanent disposal site for storage.

Schematic diagram of nuclear fuel cycle. In addition to countries that firmly take the road of one-pass and closed cycle, some countries choose to temporarily store spent fuel first.

Generally speaking, the utilization rate of uranium resources in PWR nuclear power plant is only about 0.6%. If the spent fuel is post-treated and the "squeezed" uranium is recycled once in pressurized water, natural uranium can be saved by 25%. If this cycle is repeated many times, the utilization rate of uranium resources can reach 1%;

If plutonium obtained from reprocessing and depleted uranium left after uranium enrichment are made into fast reactor fuel, the utilization rate of uranium resources can reach 60% to 70%.

Gu Zhongmao, former deputy director of the Science and Technology Committee of the Chinese Academy of Atomic Energy, wrote in 2011 that even according to the estimated amount of spent fuel discharged from nuclear power plants around the world at that time (about 10,000 tons/year), the "one-pass" circulation mode requires the world to build a geological repository with the scale equivalent to the Yucca Mountain Library in the United States (with a design capacity of 70,000 tons) every 6-7 years. As long as the installed capacity of nuclear power in the world doubles, it is necessary to build a geological repository every 3-4 years, which is obviously an unbearable burden.

Moreover, the spent fuel contains all radioactive nuclide heat sources, and the disposal space required for waste per unit volume is large.

In contrast, if the spent fuel produced by the million kilowatt pressurized water reactor nuclear power plant is 30 tons per year, its high-level radioactive waste can be concentrated in the glass body, and the radioactivity level will be greatly reduced, and the more "stubborn" long-lived radionuclides will be reduced.

The weakest link

For the construction of reprocessing, a Japanese expert once made such an analogy: Now many countries are building nuclear power plants, just like eating. Everyone is eating the best part now, but they don’t pay enough attention to the reprocessing of spent fuel. If this development continues, nuclear power will not be sustainable.

For China, where the scale of nuclear power construction in the world ranks first in the world, the decoupling between nuclear power plant construction and reprocessing development is particularly prominent. Up to now, there are 26 nuclear power units under construction in China, and 25 nuclear power units have been put into commercial operation, with a total installed capacity of 23.57GW (rated installed capacity, 1GW=1000MW, 1MW=1000KW, 1KW=1000W), and it has a blueprint for nuclear power development with an installed capacity of 58GW and a capacity under construction of more than 30GW in 2020.

With the construction and operation of nuclear power units, the production and accumulation of spent fuel will increase year by year. Relevant statistics show that by 2015, the total amount of spent fuel produced in China will reach 3,500 tons, and by 2020 it will reach about 10,000 tons.

At present, a large-scale commercial spent fuel reprocessing plant has not been built in China, and the first and only pilot plant for spent fuel reprocessing of power reactors in China was built in CNNC 404 plant in Gansu, and the annual processing capacity of the pilot project is far from meeting the needs of spent nuclear fuel reprocessing in China. Spent fuel reprocessing/recycling has become the weakest link in China’s nuclear fuel cycle.

France is a pioneer in the back-end industry of nuclear fuel cycle, with the largest, most mature and advanced commercial spent fuel reprocessing and recycling industry in the world, with an annual processing capacity of 1,600 tons, which not only meets domestic demand, but also provides services to Japan, Spain, Sweden and other countries.

Although the United States stopped commercial reprocessing activities for reasons of nuclear non-proliferation, it never stopped the research and development of reprocessing technology.

India started the research on reprocessing technology in 1950s, and it is the fourth country to run a commercial reprocessing plant after Britain, France and Russia, and its thorium fuel closed cycle route and fast reactor spent fuel reprocessing technology are at a relatively advanced level.

The urgency of building a large commercial reprocessing plant in China is not only due to huge practical needs, but also due to the three-step development strategy of "PWR-Fast Reactor-Fusion Reactor" in China’s nuclear power development in the long run. The fuel used in the fast reactor must be extracted from the spent fuel of PWR first. Without the reprocessing plant, the fast reactor will become an "island" and its operation will face the embarrassment of "cooking without rice". The design and construction of a large reprocessing plant is a complex system engineering with great difficulty, which spans 15 years or even longer.

"In the fast reactor nuclear energy system, the fast reactor is like a heart and the nuclear fuel cycle is like an artery." Gu Zhongmao, former deputy director of the Science and Technology Committee of the Chinese Academy of Atomic Energy, once said, "If the post-processing capacity does not go up, then the scale of fast reactors will not go up."

walking on two legs

Under the urgent situation, China’s independent development and the introduction of foreign advanced reprocessing plant technology are advancing simultaneously.

The above-mentioned CNN404 reprocessing pilot plant was successfully commissioned on December 21st, 2010, which indicates that China has mastered the reprocessing technology of spent fuel in power reactors.

Therefore, the significance of this pilot plant lies in: opening up the technological process of post-treatment of nuclear power plants; Inspect and verify the reliability and safety of equipment, instruments and meters; Accumulate design experience, operation experience and construction experience for future reprocessing plants with larger commercial scale.

In a sense, the successful hot commissioning of CNNC 404 Pilot Plant has also improved China’s bargaining power when introducing foreign post-processing technology and increased its bargaining chip.

In a reporter’s question-and-answer session in May last year, Wang Yiren, deputy director of the Bureau of Science, Technology and Industry for National Defense and deputy director of the National Atomic Energy Agency, clearly defined the path of China’s spent fuel reprocessing capacity: First, continue to improve the supporting facilities for the pilot plant, build the pilot plant into a comprehensive scientific research experimental platform, form a continuous processing capacity, and initially open up the road of closed cycle of nuclear fuel. Second, on the basis of the pilot post-treatment plant, carry out scientific research, optimize the main process, enlarge the key equipment, have the ability to independently design, build and operate the demonstration plant of spent fuel post-treatment, and rely on independent technology to build an industrial-scale post-treatment project. Third, actively carry out international cooperation, adhere to the principle of focusing on ourselves, and cooperate with China and foreign countries to build a large-scale post-treatment factory.

The key words are: independent development, Sino-foreign cooperation and walking on two legs.

In the "Longteng 2020" scientific and technological innovation plan released by CNNC at the end of 2012, a 200-ton large-scale commercial spent fuel reprocessing demonstration project with independent intellectual property rights was included in the first batch of eight scientific and technological innovation demonstration projects.

In 2013, CNNC signed a letter of intent for cooperation with Areva Group, a leading enterprise in the back end of the nuclear fuel cycle in the world, for a large-scale commercial reprocessing-recycling plant project, which will be built by adopting international advanced reprocessing recycling technology. After being put into operation in 2030, it has an annual reprocessing capacity of 800 tons of spent fuel.

At the end of June this year, witnessed by the Chinese and French prime ministers, Qian Zhimin, general manager of CNNC, and Philippe Knoche, CEO of Areva Group, signed the Memorandum of Understanding between China National Nuclear Corporation and Areva Group on the Road Map for Commercial Negotiation of Post-treatment/Recycling Plant Project Contract in Paris.

Guanting Reservoir will restore the function of drinking water source in Beijing in 2035.

　　Our reporter Wang Tianqi

　　Yesterday, Guanting Reservoir, the first large reservoir built after the founding of New China, celebrated its 70th birthday.

　　In May 1954, Guanting Reservoir was completed. This is the largest controlled water conservancy project on Yongding River, and it is an important barrier to stop the flood of Yongding River from threatening the downstream.

　　During the 70 years of wind and rain, Guanting Reservoir has played a great role in flood control, water supply and irrigation. From the cradle of water conservancy in new China to the vivid practice of ecological civilization construction in the new era, Guanting Reservoir keeps pace with the times and walks calmly.

　　It is estimated that by 2035, Guanting Reservoir will restore the function of drinking water source in Beijing. By then, Guanting Reservoir will glow with new brilliance.

　　The Cradle of Water Conservancy in New China

　　Guanting Reservoir is located in the upper reaches of Yongding River, at the junction of Beijing and Hebei in the northwest of Beijing. The Yongding River was flooded in history. After the founding of New China in 1949, the CPC Central Committee decided to build Guanting Reservoir to eradicate the flood and make good use of Yongding River resources. Guanting Reservoir is named because the dam is located in Guanting Town, Huailai County, Hebei Province.

　　Guanting Reservoir started construction in October 1951 and was completed in May 1954. It is the first large reservoir built after the founding of New China. Over the past 70 years, Guanting Reservoir has supplied 42.9 billion cubic meters of water and generated 8.7 billion kWh of electricity for the downstream areas of Beijing, Hebei and Tianjin. Since 1953, Guanting Reservoir has held more than 1000 cubic meters/second of floods for 8 times, basically eliminating the flood disaster in the lower reaches of Yongding River. In last year’s "23.7" catastrophic flood in Haihe River basin, Guanting Reservoir closed its floodgates and held 79 million cubic meters of flood, with a flood retention rate of 100% and a peak clipping rate of 100%, which greatly relieved the flood discharge pressure of the downstream river.

　　Guanting Reservoir is also the cradle of water conservancy in New China. In the process of building the reservoir, under extremely difficult conditions, the older generation of water conservancy experts carried out a lot of experiments and technological innovations, and invented advanced technologies, processes and equipment such as Guanting wave formula, Guanting evaporation conversion coefficient, and China’s first water level telemeter, which have been used for reference in the construction and management of other reservoirs. Water conservancy experts who have participated in the construction of Guanting Reservoir have successively invested in the construction of many reservoirs in Beijing, such as Miyun Reservoir and Ming Tombs Reservoir. Mr. Zhang Guangdou, a well-known expert in water conservancy and hydropower engineering in China, once participated in the construction of Guanting Reservoir, and later presided over the construction of Miyun Reservoir as the chief design planner, creating a miracle of "retaining flood in one year and completing it in two years".

　　Purification of incoming water quality by three constructed wetlands

　　In late spring and early summer, the No.8 Bridge wetland located at the entrance of Yongding River in the upper reaches of Guanting Reservoir is lush, with streams, small lakes and islands interwoven, which looks like a beautiful ecological picture.

　　The construction of this wetland is not to enjoy the beautiful scenery, but to purify the water in the reservoir. "No.8 Bridge Wetland has built various forms of wetlands such as forest wetlands, stream wetlands, lake wetlands, island wetlands and terraced wetlands, and planted 11 kinds of aquatic plants such as reeds, calamus and lotus flowers, which can purify water." Fu Xinlei, director of Yongding River Bank Management Office of Guanting Reservoir Management Office, said that the water coming from the upstream from west to east enters the No.8 Bridge Wetland after being adjusted by the gates of three water retaining weirs on the main river, and can stay in the wetland for 72 hours before entering the reservoir. It was found that the water quality of the upstream influent was obviously improved after the wetland purification treatment, and the removal rates of ammonia nitrogen, total phosphorus and total nitrogen in the water ranged from 26% to 88%.

　　It turned out that the water quality of Guanting Reservoir was good for more than 10 years after its completion, but since the 1970s, the water quality of Guanting Reservoir has gradually deteriorated due to industrial development, direct sewage discharge, non-point source pollution of agricultural planting around the reservoir area, and sharp drop of upstream water. Although it has been treated several times, the results are not significant. The water quality of Guanting Reservoir once reached or even worse than V in the dry season. In 1997, Guanting Reservoir was forced to withdraw from the drinking water source system of the capital, and it was only used for industrial water and environmental water of urban rivers and lakes.

　　It is urgent to pay off the water quality. In the 21st century, Guanting Reservoir has implemented a number of measures, such as dredging emergency water supply, constructing artificial wetlands, proliferation and discharge, and preventing water bloom. Ecological protection zones and sewage treatment plants have also been established in the upstream and downstream basins of the reservoir to remove pollution and improve water quality.

　　In 2003, the Heituwa constructed wetland located at the entrance of Yongding River upstream of Guanting Reservoir was opened and put into use the following year. The upstream water is purified by aquatic plants in the wetland, most of which are intercepted by suspended substances such as algae, and nitrogen, phosphorus and other substances are also effectively absorbed, and the water quality in the reservoir is obviously improved. In 2007, Guanting Reservoir resumed the function of Beijing standby drinking water source.

　　Adhere to ecological management. In 2019 and 2021, No.8 Bridge Wetland, which is about 10 kilometers away from Heituwa Wetland, and Guishuihe Wetland, which is located in the northeast of the reservoir area, were built and put into use. The three wetlands form a water purification system with high integration of water purification, water ecology and water landscape, and jointly protect Guanting Reservoir.

　　Li Xiaohong, director of Beijing Guanting Reservoir Management Office, said that at present, the constructed wetland of Heituwa, the water purification wetland of No.8 Bridge and the water purification wetland of Guishui River have formed a total wetland area of 330 hectares, with an annual treatment capacity of 153 million cubic meters. Since the operation of the three wetlands, about 1.2 billion cubic meters of upstream water has been treated. After the water flows through the wetlands, the purification effect is remarkable, and the removal rate of total nitrogen and ammonia nitrogen is the most obvious, which can reach more than 50%. "At present, the water quality of the reservoir can be kept stable at the third-class standard of surface water (except fluoride index)." Li Xiaohong said.

　　Dredging helps restore the function of drinking water source

　　In recent years, Guanting Reservoir has returned to public view because of its important position.

　　From 2001, the water storage capacity was less than 100 million cubic meters, to 2003, when Cetian Reservoir concentrated water delivery to Guanting Reservoir, and then to 2019, when the Yellow River water was transferred across the basin for the first time, the water storage capacity of Guanting Reservoir gradually increased. By April 13, 2022, the total storage capacity of Guanting Reservoir reached 692 million cubic meters, setting a new high in 26 years. Since Beijing began to try the ecological water supply of Yongding River in 2017, Guanting Reservoir has accumulated nearly 2 billion cubic meters of water supply to the downstream ecology, helping the Yongding River to pass through the whole line.

　　According to the Beijing Urban Master Plan (2016 -2035), Guanting Reservoir will resume its drinking water source function in 2035. For this goal, Guanting Reservoir is still making unremitting efforts.

　　This year, Guanting Reservoir carried out a pilot project of dredging, which has been put into construction.

　　Lai Yuan, chief designer of Guanting Reservoir Dredging Pilot Project, introduced that the pilot project plans to dredge about 11.54 million cubic meters, mainly to clean up underwater silt, and at the same time take into account the siltation area on the water beach. "The dredging scale of more than 11 million cubic meters this time is calculated according to the underwater topographic parameters of the reservoir and the designed dredging surface." Laiyuan said that on the one hand, dredging can increase the strategic water resources reserve of Guanting Reservoir, clear the area where the sediment pollution of Guanting Reservoir is relatively concentrated at present, help to further pay off the water quality, and also increase some flood control storage capacity, which provides a strong guarantee for restoring the function of drinking water source of Guanting Reservoir.

　　Laiyuan told reporters that the sediment removed through the dredging pilot project will also be recycled and consumed, and will be filled into the current gaps, ditches and pits in Huailai County around the reservoir to help the local economic construction; Part of the silt will also be made into bricks and green soil for the construction of the reservoir waterfront.

　　The dredging pilot project is planned to be completed in about two years. After the completion of the project, a professional evaluation will be conducted to determine whether the expected effect has been achieved. "This pilot dredging project is an exemplary guiding project. If the effect meets expectations, it will continue in the future." Laiyuan said that according to the calculation, in order to achieve the goal of restoring the function of drinking water source in Guanting Reservoir in 2035, Guanting Reservoir needs a total of 210 million cubic meters of dredging.

Gac ean UT reshapes the a-class car market, and the integration period is coming.

In 2025, China’s automobile industry will enter a period of great integration, and the production capacity of new energy pure electric vehicles will be further concentrated. At the same time, the Ministry of Industry and Information Technology will also approve the landing of L3-class self-driving vehicles, and China will accelerate the reconstruction of the global automobile industry. The era of electric smart cars has arrived.

In the context of the global auto industry restructuring, the recent news of the reorganization and integration of central enterprises in the whole vehicle has also caused waves in the auto circle, with traditional auto manufacturers bearing the brunt.

This great integration of the automobile industry originally originated from the new energy automobile industry.

In the past ten years, there have been many new brands in the domestic market. Under several rounds of price wars, some of them have been eliminated and some have gradually grown into well-known car companies in the industry.

This year, traditional car companies and joint venture car companies will also complete their own iterative upgrades under the wave of restructuring and integration of central enterprises, such as Guangzhou Automobile Group.

This year, Guangzhou Automobile Group not only cooperated with Huawei to complete the intelligent iterative upgrade, but also made new breakthroughs in the field of pure electric vehicles. For example, Guangzhou Automobile Ai ‘an, a new energy automobile brand under Guangzhou Automobile Group, launched Ai ‘an UT in an attempt to redefine the A-class car market.

In the A-class car market, pure electric cars have always been ordinary scooters, and because of their small size and relatively compact space, they are usually regarded as the existence of old people.

After the listing of GAC Ai ‘an UT, it redefined the industry standard of A-class cars, and made A-class cars enter the era of boutique cars from ordinary scooters, which was not only cost-effective, but also better in quality and driving experience, and was loved and sought after by young people, with a high turn-back rate on the street.

In terms of price, Ai ‘an UT69,800 started, which is more cost-effective than BYD and Geely of the same class.

In terms of driving experience, Ai ‘an UT is superior to BYD Dolphin and Geely Xingyuan, for example, it has a larger space, a higher level of configuration and a higher level of quality than its peers.

In terms of design, Ian UT is more beautiful.It is the Yan Ba in the A-class automobile market. It adopts the Milan fashion hatchback style with cute birds and big eyes. In the streets and roads, it has higher recognition, which can attract the attention of people around it and bring different visual aesthetic experiences.

Compared with BYD Dolphin and Geely Xingyuan of the same class, Milan’s stylish hatchback design is stylish and full of personality, which can bring high return rate whether it is commuting to work or in the company’s parking lot.

In the interior and exterior configuration of the car body, in addition to Milan’s fashionable hatchback and cute bird’s eye lights, Aeon UT is also equipped with a contrasting suspended roof, six Maibakh-style car paints of the same quality, and three exquisite interiors, just like a pure TV university, which brings high-quality travel experience to young people.

In terms of travel safety experience, ean UT is safer.Ai’ an UT has made all-round upgrades in terms of body safety and battery safety, bringing a safe driving experience far beyond that of its peers.

In terms of car body safety, Aeon UT has the only double-five-star car body in the same class. In the car body structure design, the proportion of high-strength steel used is as high as 71%. With the world’s first integrated high-strength side wall, it can resist high-strength impact from all directions and angles.

For example, after a rigid right-side small offset collision with 25% overlap and a 64km/h collision, not only the A-pillar will not deform, but also the door can be opened, and the battery compartment is stable without obvious impact, which brings far more safety performance than the same level.

In addition, the design of "one-piece thermoformed double door knocker", which is the only mass-produced product in the world, is currently only available in the company of Aeon UT and Tesla.

Even the weakest roof in the car body, Ian UT has achieved a safety experience far beyond its peers, and its roof design strength can withstand 8 tons of containers.

In terms of battery safety, Ian UT is also safer, equipped with a 2.0 version of the magazine battery, which not only does not catch fire in the face of shooting, but also can be used normally when twisted into a twist.

At present, the sales volume of this magazine battery carried by Ai ‘an UT has exceeded one million, and it has completed the most stringent twist test, without heating up or short-circuiting. It has also achieved zero spontaneous combustion when driving 48 billion kilometers, refreshing the limit of battery safety in the industry, and making car owners and their families really safe and worry-free.

In the ride experience, ean UT is more comfortable.With a larger circle of space, the A-class car within 100,000 class has brought the wheelbase and spatial performance of 150,000 class.

For example, Ai ‘an UT is equipped with the largest wheelbase of its class of 2750mm, the longest rear legroom of its class of 905mm, which is comparable to that of a C-class luxury car, and also has the widest rear horizontal space of its class of 1,385 mm. Three adults can also sit down calmly and the rear seat becomes more comfortable.

In terms of storage space, Ai ‘an UT has the largest trunk of its class of 440L, which has more space and can hold more luggage to meet the travel needs of a family.

At the same time, Ai ‘an UT also has the only front and rear double flattening at the same level. After the front row is put down, it is covered with a mattress, just like a luxurious big bed, which meets the needs of outdoor travel and enjoys high-quality sleep. After the back row is laid down, you can also drink coffee and listen to music in the car, which is both fun and leisure.

In addition, after both the front and rear rows are put down, Ai ‘an UT can be expanded to a huge space volume of 1,600 L, which can easily accommodate all kinds of household appliances, making moving more convenient and practical.

In terms of driving experience, ean UT is easier to drive.Ai ‘an UT is equipped with a large battery of 44KWh, which has a long battery life of 420KM, far exceeding BYD Dolphin and Geely Xingyuan in the same class, meeting the needs of short-distance commuting and long-distance driving across cities.

In terms of dynamic performance, Ian UT is equipped with quark motor and wide tires, which is not only full of power, but also more stable at high speed.

The leading 100kW quark electric drive in the same class has a top speed of 150km per hour, far exceeding the power experience of the same class. Class B wide tires with the widest width of 215mm at the same level have better grip and more stable cornering.

This kind of power configuration makes Ai ‘an UT start fast, overtake fiercely and change lanes steadily. Even if it runs at high speed and meets a big truck, it can be calm, avoid being caught in traffic, drive more stably and drive safely for a long time.

In the intelligent driving experience, Ian UT is smarter.The intelligent configuration of AI ‘an UT is more abundant. It is equipped with a dual-screen high-level intelligent cockpit and the only AI model at the same level, bringing a more advanced and higher-quality interactive experience between people, cars and machines.

In terms of intelligent parking, Aeon UT is equipped with the only reverse AEB function in its class, which can detect rear obstacles and automatic braking, prevent novice from stepping on it by mistake and accidental collision, and make reverse parking smarter and safer.

With the arrival of digital intelligent commercial times, the intelligent iteration of the automobile industry is also accelerating. With the support of joint venture car manufacturers, Ai ‘an UT has a more mature technology and product service system.

It has not only greatly improved the quality of A-class cars, but also the driving experience of sinking car users. It has also become a leader in the electrification and intelligent transformation of traditional car companies and joint venture car companies, and the future is expected.

For two days in a row, he set himself on fire to protest.

Original Qiqian observer network

Wen Observer Network Qi Qian

According to Yonhap News Agency and Korean National Daily, on March 2 and 3, local time, Zhang Ri, a member of South Korea’s ruling National Power Party, set himself on fire in front of the party headquarters in Ruyi Island, Seoul, for two consecutive days because he was dissatisfied with losing the nomination in the parliamentary election. Because the police stopped it in time, Zhang Ri was not in serious trouble and was arrested by the police on suspicion of arson on the 3 rd.

On the afternoon of the 2nd, Zhang Sunrise protested in front of the National Forces Party Department. After spraying liquid suspected of gasoline on his body, he held a lighter in his right hand, confronted the police on the scene for about 15 minutes, and then ignited his body.

After the incident, the police at the scene quickly put out the fire with a fire extinguisher and sent it to the hospital for treatment in Zhang Ri’s conscious state.

"Korean National Daily" mentioned that earlier on the 2nd, the National Power Party announced the party nomination list for the current session of the National Assembly, and Zhang Ri was unfortunately unsuccessful. During the protest, Zhang Ri said: "I have always believed that the nomination process of the National Power is clean, but in the end, this messy nomination result appeared. I came to the party department (protest) with the idea that the number of victims could not be increased. "

At about 2 pm on the 3rd, Zhang Ri once again appeared in front of the National Power Party’s Yeouido Party Department, trying to set himself on fire, but was stopped by the police.

Subsequently, the South Korean police arrested Zhang Ri on suspicion of arson, and filed an investigation on Zhang Ri on suspicion of obstructing official duties on the grounds that he tried to set himself on fire for two consecutive days and threatened the safety of the police at the scene. It is understood that Zhang Ri did not drink alcohol at the time of the incident.

Zhang Ri, who tried to set himself on fire for two days in a row, was arrested on the 3rd.

According to Yonhap News Agency, the 22nd National Assembly election will be held on April 10th.

According to the report, the results of this election will have a major impact on the power structure of the South Korean National Assembly and the national political operation of the current government. This election coincides with the middle term of Yin Xiyue’s government. The National Power Party wants to change the current pattern of "facing Xiao Ye" and thus provide support for political stability. It is expected to launch fierce competition with the Common Democratic Party headed by Li Zaiming, who vowed to "end political hegemony".

"Korean National Daily" said that the core variable that determines the outcome of this parliamentary election is South Korean President Yin Xiyue. Because this is the parliamentary election held in the third year of Yin Xiyue’s administration, this election can be regarded as an evaluation of Yin Xiyue’s performance in governing the country. However, the results of a number of recent polls show that the Korean people’s bad review rate of Yin Xiyue’s administrative performance is as high as 60%.

Explore the win-win situation of ＂green＂ and ＂rich＂ in the Yellow River Basin

　　The Yellow River Basin, which spans the eastern, central and western parts of China, is an important ecological security barrier, an important area for population activities and economic development, and plays an important strategic role in the overall situation of national development and socialist modernization. Since the 18th National Congress of the Communist Party of China, General Secretary of the Supreme Leader has visited the ecological protection and development of the Yellow River Basin for many times. With the ecological protection and high-quality development of the Yellow River basin rising to the national strategy, a series of important measures to scientifically promote ecological protection and high-quality development have successively landed. How to implement the new development concept in the new development stage and promote the Yellow River Basin to achieve a win-win situation of "green" and "rich" is an important topic to be explored in the practice of ecological protection and high-quality development in the Yellow River Basin.

　　It is of great significance to realize the win-win situation of "green" and "rich" in the Yellow River Basin.

　　Protecting the Yellow River is a great plan for the great rejuvenation of the Chinese nation. It is of great strategic significance to promote the ecological protection and high-quality development of the Yellow River Basin and achieve a win-win situation of "green" and "rich" in the Yellow River Basin.

　　The important ecological security barrier in the Yellow River Basin lays a solid foundation for economic and social development. The Yellow River Basin constitutes an important ecological barrier in China, and it is an ecological corridor connecting the Qinghai-Tibet Plateau, the Loess Plateau and the North China Plain. It has a number of national parks and national key ecological function area, such as Sanjiangyuan and Qilian Mountains. At the same time, it is also one of the regions with the largest distribution area, the most fragile ecological types and the most obvious ecological fragility in China. As an important economic zone in China, if the ecological environment problems in the Yellow River basin are not solved well, it will inevitably affect the stability and high-quality development of China’s ecological situation. Constantly consolidating the important ecological security barrier in the Yellow River Basin will lay a solid foundation for China’s economic and social development.

　　Achieving a win-win situation of "green" and "rich" in the Yellow River basin can contribute valuable experience to basin governance. Protecting the ecological environment of the Yellow River basin and promoting the high-quality economic development along the Yellow River, especially working hard to promote the win-win situation of "green" and "rich", is not only an urgent need to better coordinate the relationship between water and sediment in the Yellow River, ease the contradiction between water supply and demand, and ensure the An Lan of the Yellow River, but also a practical measure to practice Lucid waters and lush mountains are invaluable assets’s concept and prevent and resolve ecological security risks. In particular, in the process of promoting "green" and "rich" win-win, we will further explore new methods and new paths, give full play to the role of the market mechanism, better stimulate the vitality and creativity of market players, and contribute more valuable experiences that can be replicated and popularized for river basin governance in China.

　　Achieving a win-win situation of "green" and "rich" in the Yellow River Basin will inject new impetus into promoting regional coordinated development. The Yellow River basin is bordered by Kunlun Mountain in the west, Yinshan Mountain in the north, Qinling Mountain in the south and Bohai Sea in the east. It has been the national political, economic and cultural center for thousands of years. However, we should also see that in recent years, the Yellow River basin is ecologically fragile, water resources are in short supply, soil erosion is serious, the carrying capacity of resources and environment is weak, and the problems of unbalanced development along the Yellow River provinces are more prominent. If we can take the win-win situation of "green" and "rich" as the guide, closely combine the comparative advantages and development conditions of the Yellow River Basin, optimize and adjust the distribution of regional economy and productivity on the premise of ecological protection, promote the rational division of labor among the upper, middle and lower reaches, improve the development level of urban agglomerations and metropolitan areas along the Yellow River, consolidate the foundation of high-quality development of the basin, highlight its characteristics and enhance its driving force for high-quality development, it will help to promote regional coordinated development and further solve the problem of insufficient development imbalance.

　　The win-win situation of "green" and "rich" contains dialectical thinking

　　To better promote the Yellow River basin to achieve a win-win situation of "green" and "rich", we need to further understand the dialectical thinking contained in the win-win situation of "green" and "rich".

　　Overall protection and development. Relatively fragile ecology and relatively backward development are the shortcomings of the Yellow River Basin at present, and they are also two aspects of a mutually causal contradiction. If the relationship between protection and development cannot be properly handled, it will restrict the sustainable economic and social development of the Yellow River Basin. In this regard, the Supreme Leader’s General Secretary emphasized that "we should adhere to the correct view of political achievements, accurately grasp the relationship between protection and development" and "we should adhere to Lucid waters and lush mountains are invaluable assets’s concept, and adhere to ecological priority and green development", which provided guidance for promoting the ecological protection and high-quality development of the Yellow River Basin. In practice, it is necessary to unify protection and development into a coordinated development track of "green" and "rich" win-win.

　　Grasp the local and global. The Yellow River Basin is not only a huge ecosystem, but also a complex economic and social system. It is a systematic project to achieve a win-win situation of "green" and "rich" in the Yellow River Basin. We must put the concept of system into the whole process of ecological protection and high-quality development, grasp the relationship between the local and the overall situation, enhance the sense of playing chess, and focus on the overall interests on major issues. We should not only regard the watershed ecosystem as an organic whole, but also fully consider the ecological differences in the upper, middle and lower reaches, so as to adapt to local conditions; We should not only attach importance to promoting the high-quality development of the whole basin, but also highlight the comparative advantages of various places and actively explore the development path with regional characteristics; It is necessary to put ecological protection and high-quality development together in the same system, and to solve key problems in different fields.

　　Give consideration to both the present and the long term. It is a historic task to realize the win-win situation of "green" and "rich" in the Yellow River Basin. It must be noted that the current development shortcomings and weaknesses in the Yellow River Basin are the result of years of accumulation, and can never be successfully resolved in a short time. In this regard, we must grasp the relationship between the present and the long-term, take a long-term view and seriously study it, overcome the idea of quick success and quick success, and continue to advance. We should pay attention to operability and applicability, as well as continuity and stability; It is necessary to seize the day and implement it quickly, but also to persevere and make contributions for a long time; It is necessary to bear short-term pains and plan long-term interests, but also to stop losses in time and gain gains.

　　The Realistic Path of Promoting "Green" and "Rich" Win-Win

　　To promote the win-win situation of "green" and "rich" in the Yellow River Basin, we must be based on the objective reality and actual needs of ecological protection and high-quality development in the Yellow River Basin, and actively explore the realistic path to achieve "green" and "rich" win-win situation.

　　First, protect "green" with "water" and bring "wealth" with "green" The biggest contradiction in the Yellow River Basin is the shortage of water resources, and the biggest threat is the flood. In this regard, while preventing sudden floods in summer, we must also adhere to the principle of measuring water and giving priority to water conservation. It is necessary to regard water resources as the biggest rigid constraint, adhere to the principle of setting the city, land, people and production by water, optimize the ecological water use structure for production and life as a whole, use market means to force the economical and intensive use of water resources, and promote the transformation of water use mode from extensive and inefficient to economical and intensive. On the one hand, we should pay more attention to the role of market mechanism in the allocation of water resources, explore a new model of eco-economic development, and tap the economic value of water resources and water ecology; On the other hand, we should follow the laws of nature, innovate the path of water control, ensure the An Lan of the Yellow River, consolidate the water security foundation of high-quality development in the Yellow River basin, and grasp the relationship between water control and getting rich.

　　The second is to promote the balance of "green" and "rich" with spatial optimization. It is necessary to take urban agglomeration as the main spatial carrier and further optimize the layout of river basins. The key is to strictly observe the ecological red line, scientifically plan and develop, and form a virtuous circle in which ecology and development complement each other and promote each other, and man and nature coexist harmoniously. Specifically, we should gather high-quality factors based on ecological carrying capacity, accelerate industrialization and urbanization, deepen complementary advantages, strengthen the ecological support of ecological functional areas and major agricultural producing areas for the development zone and the support of production and living factors, and promote the coupling development of ecological protection and economic and social development in the spatial dimension. At the same time, strengthen the coordination between urban agglomerations, and gradually form a watershed ecological protection system with distinct regions, distinctive features, prominent priorities, clear responsibilities and organic unity, and actively promote the extension of ecological cooperation to economic and social development cooperation.

　　The third is to promote "green" and "rich" synergy with industrial development. The high-quality development of the Yellow River basin based on ecological protection needs to highlight the green background, and make the ecological industry a powerful driving force to promote the win-win situation of "green" and "rich" in the Yellow River basin. It is necessary to further improve and strengthen agriculture and animal husbandry, build a basin agricultural industrial system with green guidance, outstanding characteristics, complementary resources and sound inter-regional interest compensation mechanism, strengthen cooperation in basin agricultural science and technology, and promote the green transformation of traditional advantageous industries; It is necessary to focus on areas with strong industrial base, build a strategic emerging industry cooperation platform with effective docking of production and supply, coordinated cooperation of the upper, middle and lower reaches of the industry, and close connection of the industrial chain and supply chain in innovation chain, so as to promote the upgrading of the industrial system and the reconstruction of basic capabilities; It is necessary to improve the penetration rate of industrial internet, artificial intelligence and big data into traditional industries, further promote the greening, intelligence and digitalization of advantageous manufacturing industries in the Yellow River Basin, and inject momentum into achieving a win-win situation of "green" and "rich".
