水贫困指数在河西走廊三大内陆河流域的应用

Increasingly serious water shortage and water crisis is promoting continuous development of water resources assessment methods. Considering resources, access, capacity, use and environment, Water Poverty Index provides a simple and easy way to quantitatively assess water resources relative level at national or regional scale. Using non-balance method and combining with the subjective and objective combination determining weights method, Water Poverty Index was applied at Three Inland River Basins in Hexi Corridor. The results are basically same to the objective circumstances and combining with the WPI radar map, the main influencing factors of water resources at basins was preliminarily discussed.
