Multi-scale Water Vulnerability Assessment Research
Water vulnerability and adaptation of water system is the focus of water resources research recent days.This paper research on multi-scale water vulnerability assessment which was focus on the supply and demand of water resources,and took the Shanxi Province and Shaanxi Province as research area.Differ from conventional water vulnerability assessment,this paper chose the scale independent indices and applied the functional method to adapt to multi-scale assessment.The result showed that,the entire water vulnerability character could be found on province scale,the city scale was more spatial variable than province scale,the results of assessment on province scale could be affected remarkably from several cities,the water vulnerability increased from south to north,the variety trend of indices was the same as the water vulnerability,and the similar assessment results could be caused by various reasons.According to the results,this paper had advanced some adaptations on improving the adaptive ability to water efficiency,applying the gross water utilization control,using new water resources and control the water pollution.
