基于集对分析理论的水安全评价方法研究

针对当前水安全研究的热点问题，从集对分析理论出发，探讨了评价等级标准确定条件下的水安全评价方法。建立了待评地区（或区域）的水安全状态与不同水安全等级间的联系度表达式，依据水安全评价指标的实际值与各等级标准界限值的关系，确定了差异度系数的取值，计算了联系数，并据此进行了水安全状态的综合评价。实例的水安全综合评价及其对比分析说明了该方法的可行性。

Research on the Assessment Method of Water Security by Set Pair Analysis

In view of the current hot issue of water security research,from the set pair analysis theory,this paper discussed the assessment mothed of water security under the conditions of evaluation levels to be determined.It established connection degree formula between the area (or region) water security status and the different water security levels.Based on the relationship between the actual value of evaluation index of water security and various levels of the standard threshold,it determined the coefficient va...
