在阐述集对分析基本原理的基础上,在水资源安全领域引入了集对分析方法,运用熵权并结合总联系度值确定水资源安全等级。构建了包括经济状况、水资源条件、生活、生产和生态用水的3级评价指标体系,分析了水资源安全标准的制定特点和原则,并以河南省安阳市为例进行研究。结果表明,安阳市水资源安全等级较低,80%的评价结果属于极不安全或不安全等级。区域差异性明显,市区安全等级最高,为基本安全等级;内黄县最低,除2008年为安全等级,其余年份均为不安全等级。水资源安全具有相对稳定的发展趋势,但是全市水资源安全程度有所增强。水资源安全的影响因素与区域安全程度密切相关,提高区域水资源安全等级,必须从影响因素人手,全面改善用水的各个环节和因素。研究表明,集对分析方法和熵权理论相结合能够有效评价区域水资源安全。
Based on the basic principles of set pair analysis, this paper introduces a set pair analysis method in the field of water resources security, and uses the entropy weight and the total contact value to determine the level of water resources security. A 3-level evaluation index system including economic conditions, water resources conditions, living, production and ecological water use was constructed, and the characteristics and principles of water resources safety standards were analyzed. A case study was carried out in Anyang City, Henan Province. The results show that Anyang City, a lower level of water security, 80% of the evaluation results are extremely unsafe or unsafe levels. Regional differences are obvious, the highest level of urban safety, as the basic level of safety; Neihuang lowest, except in 2008 for the safety level, the rest of the year are unsafe levels. Water resources security has a relatively stable development trend, but the city’s water resources safety has been enhanced. The influencing factors of water resources security are closely related to the degree of regional security. To improve the level of regional water resources security, we must comprehensively improve the various links and factors of water use from the influencing factors. The research shows that the combination of set pair analysis method and entropy theory can effectively evaluate the regional water resources security.
