Advantages and disadvantages of the South to North Water Diversion Project

Advantages: The hydrological situation of the Yellow River is very complex, in order to ensure that the Yellow River crossing project is foolproof, the Ministry of Water Resources has organized the Yangtze River Design Institute and the Yellow River Committee Design Institute to independently design two schemes for the aqueduct to cross the Yellow River in the air and the tunnel to cross the Yellow River in the ground, and conduct comprehensive research and selection. After repeated arguments, the experts finally chose the tunnel piercing scheme.

Because compared with the aqueduct volleying through the yellow, the tunnel can avoid the interference of meteorological conditions such as outside temperature and climate, and the durability is better.

Disadvantages: The South-to-North Water Transfer Project will cause water resources in the south to become strained, and the shallow water layer will decline, which may lead to the withering of plant vegetation, the loss of soil nutrients, and so on.

South-to-North Water Diversion: The South-to-North Water Diversion Project aims to solve the problem of domestic and industrial water supply in more than 100 cities along the route as the main water supply object, taking into account agriculture and other water use, and the economic and social benefits will be huge after completion, which are mainly reflected in: first, it will greatly improve the ecological and environmental conditions of the northern region, especially the water resources conditions, increase the carrying capacity of water resources, improve the efficiency of resource allocation, and promote the strategic adjustment of the economic structure; It is of great strategic significance for expanding domestic demand, maintaining the rapid growth of the national economy, and realizing the structural upgrading and sustainable development of the economic and social environment on a national scale.

Second, by improving the conditions of water resources, we should promote the formation of realistic economic growth by the potential productive forces, and through the establishment of a new operating mechanism for the South-to-North Water Diversion Project, we should encourage the water-receiving areas to intensify their efforts to save water and control pollution, and gradually improve the ecological environment in the Huang-Huai-Hai region, so that the northern region of China will gradually become a water-saving and anti-pollution society with a reasonable allocation of water resources and a good water environment, so as to achieve sustainable development. Third, it can effectively solve the water quality problems caused by natural causes of groundwater in some areas in the north, such as high fluoride water, brackish water and other water sources containing harmful substances that are not good for the human body, and improve the quality of local drinking water. Fourth, it is conducive to alleviating the constraints of water shortage on the urbanization development of the northern region and promoting the local urbanization process.

The South-to-North Water Diversion Project is the largest water conservancy project in human history to cross major rivers, and is a landmark and control project for the entire middle route of the South-to-North Water Diversion Project. Its mission is to divert water from the south bank of the Yellow River to the north bank of the Yellow River, and then supply water to the area north of the Yellow River, with a design flow of 265 cubic meters per second and an increased flow of 320 cubic meters per second.
