Water Poverty Index in the Inland River Basins of Hexi Corridor, Gansu Province

Abstract

Since the economic development and environment deteriorating, water security has become an increasingly serious problem in the world. A number of regions are suffering water scarcity and pollution. The Water Poverty Index (WPI) could provide a standardized evaluation framework for the utilization and development of water resources in a certain region. This article based on the calculation of WPI, analyzed the components of WPI at basin scale, and calculated the WPI at Shule river basin, Shiyang river basin and Heihe River Basin, thereby, identified the water security and find out the main problems of water resource management and utilization in the three inland river basins in Gansu corridor.
