| 摘 要： | 地下水资源作为水资源的重要组成部分，对社会经济的健康发展具有重要的意义。以陕西省某典型灌区为研究对象，在建立TOPSIS模型过程中，以熵权对评价指标进行客观赋权，并引入“垂直距离”来代替常规TOPSIS模型中欧氏距离来改进TOPSIS模型，对灌区地下水资源承载力进行评价，结果表明，各分灌区地下水资源承载力存在差异，但总体上该灌区的地下水资源承载力潜力较小，并提出了提高地下水资源承载力的措施。研究成果对该地区地下水资源可持续利用具有重要意义。

| Abstract: | As a very important part of the water resources, the groundwater resources have important significance for the social and economic development. In this paper, a typical irrigation region in Shanxi is chosen as research object. In the process of establishing TOPSIS model, the evaluation index is weight determined objectively by entropy weight,then it improves the TOPSIS model by introducing the concept of “vertical dimension” to taking the place of the euclidean distance in the traditional TOPSIS model, afterward it uses the improved TOPSIS model to evaluate the groundwater resources carrying capacity, the results show that, there are differences in the groundwater resources carrying capacity of each subarea ,but the whole irrigation region has a less potential ,and it puts forward some measures of increasing the groundwater resources carrying capacity.The achievements has important significance for sustainable utilization of groundwater resources in this area. |
