地下水资源承载力是衡量地区经济和社会可持续发展的重要指标之一.文章以银川平原为研究对象,耦合信息熵权法和模糊综合评价法计算银川平原地下水资源承载力,并对其进行时空分析.研究表明:银川平原2006～2014年地下水资源承载力呈先上升后下降趋势,平均值为0. 358,开发潜力较小,已出现地质环境问题.从空间上看各地区间存在差异,地下水资源承载力吴忠市最高,银川市和石嘴山市次之,但总体上仍处在较低水平.需在今后发展中加强对地下水开发利用的管理.%Carrying capacity of groundwater resources has been regarded as one of the significant indicators in measuring the regional sustainable development level. In this study, fuzzy comprehensive evaluation and information entropy were used to compute the carrying capacity of water resources in Yinchuan Plain. Temporal－spatial analysis was also conducted accordingly. The results showed that the overall carrying capacity of water resources in Yinchuan Plain presented a tread of increase first but decrease subsequently from 2006 to 2014 with an average value of 0. 358, and the exploitation potential was small with many geo－environment problems. From the spatial point of view, there were obvious differences among different regions in Yinchuan Plain. The groundwater carrying capacity of Wuzhong City was higher, but that of Yinchuan City and Shijingshan City was lower, so the overall level was still low. Therefore, it was necessary to strengthen the management of development and utilization of groundwater resources in the future.
