The Ecological Environment Current Situation and the Restoration Evaluation of the Groundwater System in Beneficiary Region of Water Transfer Project from South to North
The water received area of South-to-North Water Transfer Project (SNWTP) covers six provinces and municipalities including Beijing, Tianjin, Hebei, Henan, Shandong and Jiangsu. This region holds the important strategic position in Chinese social- economic development and food safety. Influenced by the climate change, increasing population and economy development, the water received area sustain its region development by continuous groundwater exploitation, which has caused a series of ecological environment problems, such as groundwater exhaustion cones caused by the partly aquifer dewatering, land fracture caused by the unevenly land subsidence and salty fresh water layer caused by the sea water intrusion, etc. All these problems have limited the region economy development. According to the groundwater overwithdrawal reduction scheme of the SNWTP beneficiary region, groundwater overwithdrawal reduction rate in water received area in 2020 will reach 60％. This will make the groundwater tables, the aquifer reserves and the land subsidence develop into a good direction. Therefore, the SNWTP will not only have the significant importance in improving the beneficiary regions social economy development, but also have the remarkable effect in improving the regional ecological environment situation.
