基于模糊集对分析法的新疆水资源安全评价

Xinjiang water resources security evaluation based on fuzzy set pair analysis

根据区域水资源现状,选取18个评价指标,建立了包括水资源、经济社会、生态环境、供需4个准则层的区域水安全评价指标体系;通过熵权法确定指标权重,采用基于模糊集对分析的水资源安全评价方法,对2016年新疆水资源安全状况进行了评价。结果表明:新疆水资源整体的安全状况属于基本安全等级,空间分布上北疆优于南疆和东疆;评价结果与物元分析法和综合指数法评价结果总体上一致,评价结果具有合理性。

According to the current situation of regional water resources,18 evaluation indexes were selected and an evaluation index system of regional water security was established,which includes four criteria levels:water resources,economic society,ecological environment,supply and demand.The index weight was determined by entropy weight method,and the water resources security evaluation method based on fuzzy set pair analysis was used to evaluate the water resources security situation of Xinjiang in 2016.The evaluation results show that the overall security of water resources in Xinjiang belongs to the basic security level,and the spatial distribution of Northern Xinjiang is better than that of southern and eastern Xinjiang.The evaluation results are generally consistent with the results of matter-element analysis and comprehensive index method,and the evaluation results are reasonable.
