基于集对分析与可变模糊集理论的区域水资源承载力评价

Evaluation of Regional Water Resources Carrying Capacity Based on Set Pair Analysis and Variable Fuzzy Set

在建立由水资源承载支撑力、水资源承载压力和水资源承载调控力3个子系统共15个指标组成的水资源承载力评价指标体系及其评价标准的基础上,提出用集对分析方法构造可变模糊集的相对差异度函数,建立集对分析-可变模糊综合评价模型。应用所建模型对2017年亳州市水资源承载力进行评价,得出综合评价等级为3级,属于超载,水资源开发利用已达到一定规模。研究结论与实际情况相符,验证了模型的适用性。

The evaluation index system of water resources carrying capacity which consists of bearing ability system, bearing pressure system, regulation ability system of water resources and 15 indexes were established, then the evaluation criteria were determined. On this basis, a method was presented to establish the relative diversity degree function of variable fuzzy set using set pair analysis method, which combined with fuzzy comprehensive evaluation can form a new model, named the integrated model of set pair analysis and fuzzy comprehensive evaluation. Its application to the water resources carrying capacity evaluation in Bozhou City in 2017 shows that the comprehensive assessment grade is 3 grade, reaching the over load level. The water resources development and utilization have reached a certain scale. The results coincides with the actual situation, which validates the applicability of the model.
