摘要:

为了分析我国各流域的水资源短缺现状,引入欧盟开发改进的水资源开发利用系数(Water Exploitation Index Plus,简称WEI+),以全国10个水资源一级区作为研究对象,计算2003—2012年各水资源一级区的水资源短缺情况。结果表明①WEI+指数最小的是西南诸河区,其均值为1.9%;WEI+指数最大的是海河区,其均值为130%;且南方4区的WEI+指数均小于北方6区,说明我国北方比南方面临更为严重的水资源短缺问题。②南方4区的WEI+指数在2003—2012年间波动不大,而北方6区的WEI+指数波动剧烈;大部分地区的WEI+指数均呈现出下降趋势,这说明区域的水资源短缺情况有所缓解。③WEI+指数与流域水利水电开发利用程度在空间上的分布规律基本类似,这说明WEI+指数能够有效反映区域的水资源短缺情况。

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.

Key words: water scarcity, Water Exploitation Index Plus(WEI+), first-grade districts of water resources, four basins in South China, six basins in North China
