Study of Measures for Sustainable Water Resource Utilization and Sound Eco-environmental Maintaining of the Weihe River Basin

摘要

The Wei River is the largest tributary of the Yellow River, which runs through Gansu, Ningxia and Shaanxi provinces (autonomous region), across the rich Guanzhong Plain, and plays an important role in the Yellow River management and regional economic development. The river basin has inadequate total volume of water resources, and with rapid development of economy and society, conflicts between water demand and supply are increasingly acute, and water shortage has become an important factor restricting sustainable utilization of water resources and sound maintaining of ecological system of the basin. Under the conditions of intensive water saving and efficient utilization of existing water resources, implementation of the trans-basin water diversion project is the important approach to resolving water shortage, promoting economic and social development of the basin and maintaining the basic function of the river channel.
