Where is the source of the South-to-North Water Transfer Project?
The source of the South-to-North Water Diversion Project is divided into east, middle and west lines. The east line originated from Jiangdu Water Control Project in Yangzhou, Jiangsu Province, and the middle line originated from Danjiangkou Reservoir in the middle and upper reaches of the Han River. The west line project is still in the planning stage, and construction has not started.
Since the completion of the South-to-North Water Transfer Project in 20/KOOC-0/4, South Water has become the main water source for more than 40 large and medium-sized cities such as Beijing and Tianjin, and more than 280 counties and cities/KOOC-0/400,000 people. By May, 2022, 13, the cumulative water transfer capacity of the east and middle routes of South-to-North Water Transfer Project will reach 53 10 billion cubic meters. Among them, 8.5 billion cubic meters of ecological water supply was implemented for more than 50 rivers along the line, reducing groundwater overexploitation by more than 5 billion cubic meters for the receiving area.
The water source area of the Middle Route of South-to-North Water Transfer Project includes Danjiangkou Reservoir Area and its upper reaches, involving 49 counties (cities, districts) in 6 provinces and cities of Henan, Hubei, Shaanxi, Sichuan, Chongqing and Gansu, covering an area of 95,000 square kilometers. Since the start of the reservoir project in 2005, with the efforts of 16 years, the water source area is now covered with green mountains and green waters, with trees and birds singing, showing a beautiful picture.
Achievements of South-to-North Water Transfer Project
As of June 5,438+1October 7, 2022, the first phase of the East Middle Route of South-to-North Water Transfer Project has a total water transfer capacity of 50 billion cubic meters, including 5.288 billion cubic meters on the east route and 44.7/kloc-0.20 billion cubic meters on the middle route, which is of great significance for optimizing water resources allocation, ensuring people's drinking water safety, restoring the ecological environment of rivers and lakes, smoothing the economic cycle between north and south, and helping the country.
Since the first phase of the East Middle Route of the South-to-North Water Transfer Project was put into use, it has benefited more than 40 large and medium-sized cities and more than 280 counties (cities, districts) in 7 provinces and cities along the route, including Henan, Hebei, Beijing, Tianjin, Jiangsu, Anhui and Shandong, with a direct beneficiary population of more than 654.38+0.4 billion people. The project has become the lifeline of water supply for cities along the route. The water quality of the eastern trunk line reached the Class III standard of surface water, the water quality of the central trunk line was stable at Class II standard or above, and the drinking water quality of the people along the line was significantly improved. More than 7.6 billion cubic meters of ecological water have been replenished by more than 50 rivers in the north, and the ecological environment of rivers and lakes along the route has been effectively restored, which has promoted the restoration of vitality of a large number of rivers and lakes such as Hutuo River, Pupu River, Nanjuma River, Daqing River and Baiyangdian, and the Yongding River has been fully flooded for the first time since 1996.
Brief introduction of South-to-North Water Transfer Project
The South-to-North Water Diversion Project has three routes: East, Middle and West. The eastern route starts from Yangzhou Jiangdu Water Control Project and ends in Tianjin. The central line starts from Danjiangkou Reservoir and ends in Beijing. The western front has no beginning, no beginning and no end. The South-to-North Water Transfer Project is a strategic project in China. Upon completion, the overall layout with "four horizontals and three verticals" as the main body will be realized, and the rational allocation pattern of water resources in China will be realized.
The South-to-North Water Transfer Project is a major national strategic project aimed at the reality of floods in the south and droughts in the north of China, alleviating the shortage of water resources in North China and Northwest China and promoting the coordinated development of economy, society, population, resources and environment in the north and south. The project is divided into east, middle and west water transfer lines, which are interconnected with the Yangtze River, Yellow River, Huaihe River and Haihe River, forming a layout with "four horizontals and three verticals" as the main body.
Unlike the previous water transfer projects at home and abroad, which were mostly single-objective, the South-to-North Water Transfer Project was multi-objective. It is not only a water resources allocation project, but also a comprehensive ecological project that benefits the people. It will greatly improve the carrying capacity of water resources and water environment in the water-receiving areas (including more than 0/00 water-receiving cities along the line), and repay some agricultural and ecological water occupied by cities to agriculture and ecology.
In a sense, this is a vivid reflection of Scientific Outlook on Development's water resources security, in which industry feeds back agriculture and cities feed back rural areas.
The total planned water transfer scale of the South-to-North Water Transfer Project is 44.8 billion cubic meters, which has remarkable social, economic and ecological benefits. It can effectively solve the problem of water shortage in the northern region, promote the economic and social development and urbanization process in this region, and make more than 7 million people get rid of drinking high-fluorine water and brackish water for a long time. In addition, it can effectively alleviate the over-exploitation of groundwater in the receiving area, thus curbing the deterioration trend of water ecology in the northern region and gradually restoring and improving the ecological environment.
