基于模糊四元联系数的区域水资源承载能力评价方法研究

Research on the evaluation method for regional water resources carrying capacity based on fuzzy four-element connection number

【目的】建立合理的区域水资源承载能力评价方法,为准确地评价特定区域水资源承载能力、制定和实施该地区发展规划提供参考。【方法】将集对分析理论引入水资源承载能力研究领域,利用四元联系数分析各评价指标之间的优劣关系,并通过各指标权重关系确定区域水资源承载能力所属等级,建立区域水资源承载能力评价的模糊四元联系数模型。【结果】应用所建立的基于模糊四元联系数的区域水资源承载能力评价方法,对安徽省淮北市的实际应用结果表明,淮北市当前水资源承载能力发展形势严峻,已趋近饱和,但随着经济的发展,总体状况会有所好转;所建立的评价方法计算过程合理可靠、简便快捷,计算结果与实际相符。【结论】基于模糊四元联系数的区域水资源承载能力评价方法,能较好地描述复杂系统内部要素之间的优劣差异变化情况。

[Objective] The study was to establish an reasonable evaluation method for regional water resources carrying capacity,so as to provide important decision basis for evaluating regional water resources carrying capacity accurately,making and applying the regional developing plans.[Method] The set pair analysis method was introduced into water resources carrying capacity research field,and four-element connection number was used to describe the differences between the evaluating indexes,and then the correspond...
