Logo pattern of South-to-North Water Transfer Project

According to the water quality protection situation of the Middle Route Project of South-to-North Water Diversion Project jointly notified by the State Council South-to-North Water Diversion Office and the Ministry of Environmental Protection, the water quality of the reservoir area and the incoming rivers is excellent as a whole.

In China, the drinking water must meet the requirements of Class III water at least, but according to the report, the water quality of Taocha water intake of Danjiangkou Reservoir currently meets the requirements of Class II higher than Class III water. The water quality compliance rate of the main inflow rivers is 97.4%. However, most of the water in Danjiangkou Reservoir comes from Hanjiang River, and the water quality of Hanjiang River, which accounts for 9% of the total inflow, is stable. The water quality analysis of Danjiangkou Reservoir shows that the water quality of Danjiangkou Reservoir is also stable.

The substandard section is mainly located in the river section with small runoff and flowing through the lower reaches of the town, which has little impact on the water quality of Danjiangkou Reservoir. For example, the five rivers that pass through Shiyan City, namely Shending River, Sihe River, Yaohe River, Guanshanhe River and Jianhe River, although the water volume is very small, accounting for less than 1% of the total water inflow, after the current regulation, the water quality of the five rivers is neither black nor smelly, and some of them have become Class III water, while others have also changed from inferior V and V to Class IV water.

On October 14th, 214, Jun Gao, director of the Rural Economic Department of the National Development and Reform Commission, responded to the serious water pollution problem in the South-to-North Water Transfer Project. The initial planning and design of the South-to-North Water Transfer Project focused on urban water supply, giving consideration to agricultural and ecological water use. From the middle route of South-to-North Water Transfer Project, the water quality of Danjiangkou Reservoir is relatively good, and some tributaries have water pollution problems, but it does not affect the overall situation.

the development and reform commission and other relevant departments attach great importance to the water pollution problems in individual places, individual pollution points and individual tributaries, and are taking serious measures to prevent and control them. The water quality problems of the Middle East Line of the South-to-North Water Transfer Project have generally reached the expected planning and design goals. 1. The simultaneous diversion of water from the "three lines" will lead to incalculable changes in the ecology along the Yangtze River, which is not conducive to protecting the existing ecology along the Yangtze River. And it may lead to the lower carrying capacity of the waterway during the dry season of the Yangtze River. The scope and extent of its ecological impact have gone far beyond the understanding of China "experts".

2. The interaction between the Middle Route Project and the Three Gorges Project will cause environmental changes in the middle and lower reaches of the Hanjiang River and the Yangtze River, which will cause incalculable losses to Wuhan.

3. The influence of water diversion from the eastern route project on the Yangtze River estuary area leads to secondary salinization of soil in the northern irrigation area. First, the South-to-North Water Diversion Project has aroused widespread social debate since it was put forward. Opponents mainly think that the South-to-North Water Diversion Project is costly, involving a large number of immigration problems, and the water regulation is too small to bring economic benefits into play, and the water regulation is too large. The dry season may make the Yangtze River water shortage, affect the navigation of the Yangtze River channel, and deepen the salt tide in the Yangtze River estuary, which is more likely to trigger a natural environmental and ecological crisis in the Yangtze River basin.

second, after the implementation of the South-to-North Water Transfer Project, the original flood storage and power generation functions of the Three Gorges Project have been controversial. The simultaneous effects of the Three Gorges Project and the South-to-North Water Diversion Project may have incalculable impacts on the middle and lower reaches of the Yangtze River (including ecology and shipping), especially in dry season and dry season.

Third, because of the drought in southwest China in early 21, Liu Shukun, chief engineer of Institute of Hydraulics of China Academy of Water Resources and Hydropower Research and chief engineer of Disaster and Environment Research Center, questioned the South-to-North Water Transfer Project. He believes that the once-in-a-century drought in southwest China should be revised, and the frequency and possibility of drought should be reassessed.

4. The relocation of 33, people in Hubei Province and Henan Province in the Middle Route of South-to-North Water Transfer Project has brought turbulence to the lives of immigrants. Some immigrants can only buy a small piece of cultivated land after buying the housing provided by the government because of insufficient compensation.

5. The cost of the South-to-North Water Diversion Project is already higher than the existing cost of seawater desalination. At present, the lowest cost of seawater desalination is about 3 yuan, and the current cost of the South-to-North Water Diversion Project is about 1 yuan. It is also reported that it has reached 18 yuan.

in the first half of 211, Hunan, Hubei and Jiangxi, three provinces in the lower reaches of the Three Gorges, suffered unprecedented drought, and more than 1,3 reservoirs in Hubei province alone were below the stagnant water level. The water levels of Poyang Lake, Dongting Lake and Hongze Lake are seriously low, and the largest freshwater lake in China has only one tenth of the water area. This series of events has aroused widespread doubts about the Three Gorges Dam from all walks of life.
