The Yangtze River floats with jade belts for thousands of miles, and the tide rushes to draw grand plans. From the source of the three rivers to the Three Gorges Reservoir area, and then to the Huangpu River, the Yangtze River basin has been linked by water for thousands of years, connecting the upper, middle and lower reaches, left and right banks, trunk and tributaries, forming a complete Natural economy and social system, and creating a millennium cultural context from Bashan to Jiangnan. From the Chengdu Chongqing dual city economic circle to the urban agglomeration in the middle reaches of the Yangtze River, and then to the integration of the Yangtze River Delta, the Yangtze River Economic Belt covers 11 provinces and cities along the Yangtze River, spanning the three major plates of China's east, middle, and west. The population size and total economic output account for half of the country's "rivers and mountains". Emphasizing the need to "make the Yangtze River Economic Belt the main battlefield for ecological priority green development in China, open up the domestic and international dual circulation arteries, and lead the main force for high-quality economic development." Harmony between people and water: Write a new chapter of ecological priority green development. In Yichang, Hubei, the Maoping Cruise Terminal of Zigui Port upstream of the Three Gorges Dam is peaceful and peaceful. Although there is no pungent diesel smell or engine roar, the "Three Gorges 10" cruise ship docked here is brightly lit. Yichang is the location of the Three Gorges Dam and Gezhouba Dam. Since 2015, the local government has been exploring shore power construction. As of the end of May this year, various types of ships in the Yichang section of the Yangtze River have used a total of 26.34 million kilowatt hours of shore power, equivalent to 6190 tons of alternative fuel, reducing harmful gas emissions by 19500 tons, and saving energy costs for ships by over 30 million yuan. "Li Xingheng, a shore power operation and maintenance service personnel at State Grid Yichang Power Supply Company, said that pollution emissions have decreased, the environment in the Three Gorges Reservoir area has improved, and the quality of tourism has also significantly improved. Under the night, the high gorge and flat lake were stagnant with waves. The scene depicted in a poem by Tang Dynasty poet Du Fu over 1000 years ago, is now a new chapter in the harmony between people and water in the magnificent Three Gorges Reservoir Area. A good ecological environment is the most inclusive welfare for people's livelihoods. However, due to the direct discharge of sewage into the river, the encirclement of the river by chemical enterprises, and the accumulation of sand and gravel at docks, the water quality of the Yangtze River has continued to deteriorate and its ecological functions have deteriorated, sounding an alarm for the ecosystem. To cure the Yangtze River disease, it is necessary to scientifically apply the holistic view of traditional Chinese medicine, trace the root cause, diagnose the cause, identify the root cause, classify and implement strategies, and systematically treat it. The Wujiang River Basin was once plagued by pollution incidents due to the dense production base of phosphorus chemical industry. Guizhou Province has closed a batch of small and medium-sized phosphate mines with outdated technology and low resource mining efficiency in accordance with the concept of "addressing both the root cause and root cause, prioritizing the source, and covering the bottom"; Actively utilizing advanced process technology and equipment transformation to enhance the refinement level of the phosphating industry; Take the lead in implementing "slag based production" in the country, and force phosphorus chemical enterprises to improve the comprehensive utilization rate of Phosphogypsum resources... In 2022, among the 92 monitoring sections of the Wujiang River system, Class I to Class III water quality sections account for 96.7%, and the overall water quality is "excellent". Comprehensive renovation of the Yangtze River shoreline, transformation from customs reform to green transformation of chemical enterprises along the river, source tracing renovation of sewage outlets into the Yangtze River, and 10 years of key waters in the Yangtze River basin
