基于WEI+的流域水资源短缺分析
Water Scarcity Analysis of River Basins in China Based on Water Exploitation Index Plus
摘要
Abstract
In the aim of assessing the water scarcity situation of river basins in China,Water Exploitation Index Plus(WEI+)developed by European Union was introduced to compute the water scarcity situations from 2003 to 2012 in ten first-grade districts of water resources in China.Results show that the WEI+ in rivers basin in Southwest China is the smallest,with the average value of 1.9%,and that of Haihe River Basin is the largest,with the average value of 130%.The WEI+ values of six basins in the North are larger than those of four basins in the South,indicating a severe water scarcity situation in North China.The WEI+ values of four basins in the South changed little during 2003-2012,while those of six basins in the North fluctuated greatly.Moreover,the WEI+ values of most river basins displayed a downward trend,showing the alleviation of water scarcity situation.In addition,the spatial distribution pattern of WEI+ is generally similar with that of water conservancy development and utilization degree,which indicates that WEI+ could effectively reflect the regional water scarcity situation in China.关键词
