【摘要】：后套平原地下水资源分布不均,人口和经济集中于城镇,地表水漫灌导致了土壤盐渍化,对地区社会经济可持续发展造成了严重影响。因此,评价地下水可持续性已经成为该地区发展规划首先要解决的问题。地下水可持续性可以直观有效地反映一个地区地下水利用程度,对地下水资源管理具有重要参考价值。以后套平原地区地下水开采面临的问题为出发点来选择评价指标,利用综合评价方法计算了评价单元上的地下水可持续性水平。结果显示,黄河南岸和东北部地区可持续性最差,中部北部地区可持续较好,地下水资源的开发潜力较大的行政区位于杭锦后旗和五原县北部,而磴口县和乌拉特前旗大部分地区地下水可持续性差,荒漠化严重,不宜再继续发展耗水产业。
[Abstract]:The distribution of groundwater resources is uneven, the population and economy are concentrated in cities and towns, and the surface water irrigation results in soil salinization, which has a serious impact on the sustainable development of social economy in the region. Therefore, the evaluation of groundwater sustainability has become the first problem to be solved in the regional development planning. Groundwater sustainability can directly and effectively reflect the degree of groundwater utilization in a region and has important reference value for groundwater resources management. In the future, the problems of groundwater exploitation in plain area are selected as the starting point to select the evaluation index, and the sustainable level of groundwater on the evaluation unit is calculated by using the comprehensive evaluation method. The results show that the south and northeast of the Yellow River have the worst sustainability, and the central and northern regions have better sustainability, and the administrative regions with great potential for groundwater resources development are located in the northern part of Hangjin Houqi and Wuyuan County. However, the groundwater sustainability is poor and desertification is serious in most areas of Dengkou County and Ulat Qianqi, so it is not suitable to continue to develop water consumption industry.
