一、宁夏水资源供需的五大矛盾近年来,宁夏经济社会持续快速发展,水资源供需面临的矛盾日益突出,主要表现在五个方面:资源性缺水严重。全区平均每年可利用水资源总量为51.73亿立方米,其中,当地可用水资源总量11.73亿立方米;黄委会分配给宁夏的黄河可耗水指标为40亿立方米。宁夏人均可耗水量893立方米,分别为黄河流域和全国平均值的二分之一和五分之二,远低于国际上公认的重度缺水区人均1000立方米的标准。
I. The Five Conflicts between Supply and Demand of Water Resources in Ningxia In recent years, the economy and society in Ningxia have maintained a sustained and rapid development. The contradiction between supply and demand of water resources has become increasingly prominent. There are mainly five aspects: the serious shortage of water resources. The average annual total available water resources in the region is 5.173 billion cubic meters, of which 1.173 billion cubic meters of water is available locally. The Yellow River Water Consumption Indicator allocated by the Yellow River Committee to Ningxia is 4 billion cubic meters. Ningxia per capita consumption of 893 cubic meters of water, respectively, the Yellow River and the national average of one-half and two-fifths, well below the internationally recognized severe water-deficit per capita 1,000 cubic meters standard.
