宁夏地下水资源开发利用现状及存在的问题分析

Current Situation and Problems Analysis on Development and Utilization of Groundwater Resources in Ningxia

宁夏回族自治区位于我国西北内陆,水资源匮乏,地下水作为重要的供水水源,其供需矛盾日益突出。通过统计全区现有地下水水源地的允许开采量及实际开采量,分析其开发利用情况,结果表明,现状开采条件下,统计的全区34个水源地中,有2个超采,其中石嘴山市第一水源地超采严重。对全区地下水超采区尽心统计,超采区达5个,其中银川市有1个,石嘴山市有4个,超采量高达5 432万m^3。

The Ningxia Hui Autonomous Region is located in the northwest of China,where there is a lack of water resources,groundwater acts as an important water source,and the contradiction between supply and demand of groundwater becoming increasingly prominent. Base on the statistics of allowable exploitation quantity and actual exploitation amount,its development and utilization condition were analyzed. The results showed that,under the condition of the current mining condition,in the region＇s 34 groundwater sources,2 were overdraft,and the situation of the first water source in Shizuishan is more serious. Moreover,Statistical result of the region＇s excess exploitation place show that the overdraft area amounted to 5,Yinchuan city has 1 and Shizuishan city has 4,the overexploitation is up to 54 320 thousand m-3.
