宁夏水资源利用现况与水资源量变化规律分析

以为宁夏水资源合理开发利用提供理论保障为研究目的,利用宁夏2002~2007年水资源数据,在研究分析宁夏水资源开发利用现状的基础上,通过统计学理论和回归分析的方法研究了宁夏降水资源量、当地地表水资源量以及地下水资源量的变化规律。结果表明,宁夏水资源利用存在着结构性矛盾,农业耗水量过大,生态用水量不足。降水量变化具有周期性,变化周期为4~5 a,地下水资源量呈线性逐年减小,减小速率为0.51×108m3/a,地表水资源量受降水量影响较大,与降水量变化趋势基本一致。最后为宁夏水资源合理开发利用提出了几点建议。

Waters Resources Status and Change Law in Ningxia

For the purpose of offering theoretical support for the rational exploitation of water resources in Ningxia,collected water resources data from 2002~2007,and on the basis of analysis of water resources status,analyzed the change law of precipitation,surface water and groundwater with theory of statistics and regression analysis.After analysis,we came to the conclusion that agriculture cost too much water while ecological environment uses little water which is a structural contradiction in the process of wat...
