以新疆较为干旱的喀什区域为研究对象,将区域划分为8个分区,该区域地下水资源占据总水资源量的40%以上,是区域水资源的重要组成部分。选取11种地下水安全影响指标构建地下水安全指标体系,通过构建新疆喀什地区地下水安全评价指标体系,结合熵权云模型对区域地下水供水安全进行定量评估。评估结果表明:熵权云模型可综合考虑地下水安全评估的随机性和模糊性,评估结果和实际情况吻合度较高,喀什地下水供水安全综合评价值在0.094 5~0.252之间。区域地下水供水总体达到较安全的程度。研究成果对于地下水供水安全评估提供新的方法参考。
Taking the more arid Kashgar region in Xinjiang as the research object, the region is divided into eight sub-regions. The groundwater resources in this region occupy more than 40% of the total water resources, which is an important part of regional water resources. Eleven groundwater safety indicators were selected to construct the groundwater safety index system. The groundwater safety evaluation index system was established in Kashi, Xinjiang, and the entropy weight cloud model was used to quantitatively assess the groundwater safety. The evaluation results show that the entropy cloud model can comprehensively consider the randomness and fuzziness of groundwater safety assessment. The assessment results are in good agreement with the actual situation. The comprehensive assessment value of groundwater safety in Kashgar ranges from 0.094 5 to 0.252. The overall groundwater supply in the region has reached a relatively safe level. The research results provide a new method reference for the safety assessment of groundwater supply.
