Time of the first phase of South-to-North Water Transfer Project

"South-to-North Water Diversion Project" (pinyin: nán ShuǐbīI diào), namely "South-to-North Water Diversion Project", is a strategic project of China people, which is divided into three routes: east, middle and west. The starting point of the East Line Project is located in Jiangdu Water Control Project in Yangzhou, Jiangsu Province. The starting point of the middle route project is located in Danjiangkou Reservoir in the middle and upper reaches of Hanjiang River, and the water receiving areas are Henan, Hebei, Beijing and Tianjin.

The conception of the engineering scheme began with 1952 [2]? Chairman and Mao Zedong proposed it when they visited the Yellow River. Since then, through the analysis and comparison of more than 50 schemes, the water transfer scheme has achieved many valuable results. The planning area of South-to-North Water Transfer Project involves a population of 438 million, and the water transfer scale is 44.8 billion cubic meters. [3]? The total length of the east, middle and west trunk lines planned by the project is 4350 kilometers. The first phase of the East and Middle Lines is 2,899 kilometers long, and the first-class supporting branch canals in six provinces and cities along the line are about 2,700 kilometers.

From 2065438 to September 2002, the relocation of migrants in Danjiangkou reservoir area of the Middle Route of South-to-North Water Transfer Project was fully completed. The South-to-North Water Transfer Project mainly solves the problem of water shortage in northern China, especially in the Huang-Huai-Hai River Basin, with a population of 438 million. * * * There are three water transfer lines, namely the East Line, the Middle Line and the West Line, which are connected with the Yangtze River, the Yellow River, the Huaihe River and the Haihe River, forming an overall layout with "four horizontals and three verticals" as the main body, which is helpful to realize the rational allocation pattern of water resources in China.

The Middle Route Project of South-to-North Water Transfer and the East Route Project of South-to-North Water Transfer (Phase I) have been completed, and water has been transferred to the northern region. 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.
