The main reason for building the national South-to-North Water Transfer Project is to improve the natural environment in North China and Northwest China and promote the harmony between man and nature. At the same time, it will effectively solve the serious water shortage problem in North China and Northwest China, mobilize the growth potential of these areas, expand development opportunities, improve the efficiency of resource allocation, and promote the strategic adjustment of economic structure.
The implementation of the South-to-North Water Transfer Project is the material guarantee for China to achieve balanced regional development and build a well-off society in an all-round way. Although China has basically achieved the goal of a well-off society, the contradiction of unbalanced economic and social development has become increasingly prominent. There are many reasons for this development gap, among which the shortage of water resources is one of the important reasons for the backward economic development in North China and Northwest China.
The implementation of the South-to-North Water Transfer Project is conducive to stimulating domestic demand and expanding employment. The research results of the State Council Development Research Center show that the construction of South-to-North Water Transfer Project will directly stimulate economic growth and increase employment opportunities along the route. According to the preliminary estimate of 10 during the construction period, the investment in the South-to-North Water Transfer Project in the near future will boost GDP growth by 0. 12 percentage points annually on average, and further expand its impact on economic growth through multiplier effect.
South-to-North Water Diversion Project:
The South-to-North Water Diversion Project is a strategic project in People's Republic of China (PRC), 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, Yangzhou City, 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 was put forward in 1952 when President Mao Zedong 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. 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 eastern line, the central line and the western line. Through the connection of three water transfer lines with the Yangtze River, the Yellow River, the Huaihe River and the Haihe River, the overall layout with "four horizontals and three verticals" as the main body is formed, which is conducive to realizing 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.
