Abstract: An indicator called Water Supporting Index (WSPI) was built to measure the degree of water scarcity, which considered water resources and water withdrawal of both local and upstream areas. An evaluation model was established to calculate WSPI of 210 sub-basins and also in province scale and county scale. Water resources supporting capacity classes to regional socio-economic development was divided by WSPI. The spatial status of the capacity classes and its relationship with population and Gross Domestic Product were analyzed. Furthermore, the differences in regions suffering water scarcity were discussed. The result of WSPI was very similar to the actual water scarcity situation of China. Therefore, WSPI can be used in water resources management and socio-economic development decision-making.

Key words: water resources, regional socio-economic development, water scarcity, Water Supporting Index, WSPI, water resources supporting capacity
