Overall Solution of Ecological Restoration and Drinking Water Safety in Semi-arid Region of Loess Plateau

In the semi-arid region of the Loess Plateau，there are less precipitation，more evaporation，fewer water resources，and extremely fragile ecological environment.With rapid development of social economy and population scale，economic resources and ecological environment in the region are facing more pressure.Most rivers are seriously polluted and have lost their ability to repair and purify themselves.The underground water level has dropped sharply，causing serious drinking difficulties for people and livestock in cities and rural areas.Taking Fenhe River Basin as an example，the water environment and water ecological status of the basin were analyzed in detail，and comprehensive improvement measures were put forward：in the semi-arid region of the Loess Plateau where the ecology was fragile，the concept of water conservancy development in the new era of people-oriented and ecological priority must be adhered to，traditional concept of water conservancy projects focusing on industrial and agricultural water use should be completely abandoned，and the water conservancy projects of people's livelihood should be taken as the starting point for large-scale construction and large-scale development，so as to comprehensively solved the urban and rural water diversion，water supply and drainage projects，drinking water safety projects and sewage treatment projects and give priority to ensuring the drinking water.
