What does the South-to-North Water Transfer mean? thank you

The South-to-North Water Diversion Project means:

The South-to-North Water Transfer 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 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 supply 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 a lot of valuable results.

The planning area of South-to-North Water Transfer Project involves 438 million people, and the water transfer scale is 44.8 billion cubic meters. The east, middle and west trunk lines planned by the project have a total length of 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.

Extended data:

By the end of 20 19, the East Route Project of South-to-North Water Diversion made full use of the existing engineering system and cascade structure, and improved the water diversion capacity by building 1 1 pumping station and rebuilding and expanding three large pumping stations.

Expand the capacity of rivers and lakes along the line, tap the potential of water storage and distribution, and improve the water supply system of the first line and the second line of the canal. The South-to-North Water Transfer Project was upgraded and the scale of pumping water was expanded to 500 cubic meters per second. The annual total water transfer capacity is close to 65.438+088 billion cubic meters, and the annual net water supply is 3.6 billion cubic meters.

Jiangsu coordinates the allocation of multiple water sources and local rain and flood resources in rivers, Huaihe River and Yishu River; Comprehensive urban life and agricultural irrigation, shipping and ecology, and multi-demand security inside and outside the province; Ensure the multi-objective task of water delivery time, water quantity and water quality, and realize the "unified dispatching and joint operation" of the new line project of South-to-North Water Transfer and the project of diverting water from the Yangtze River to the North.

In the past eight years, the first phase of the East Route of South-to-North Water Transfer Project has transferred more than 4.7 billion cubic meters of water to Shandong. At the same time, it also provided a stable water source for the water receiving area around Hongze Lake in Anhui Province, supported the first phase of the East Route of South-to-North Water Transfer Project to extend emergency water supply to Hebei and Tianjin, and made an important contribution to alleviating the water shortage crisis in northern China.
