广西北部湾经济区水资源承载力评价方法初探

采用基于AHP的水资源承载力模糊物元模型对广西北部湾经济区水资源承载力进行评价。在分析北部湾经济区水资源承载力的基础上，将影响水资源承载力的主要评价指标组成模糊物元，以各项评价指标及其相应的模糊量值构造复合模糊物元，构建了北部湾经济区水资源承载力指标体系，运用层级分析法（AHP）确定各评价指标的权重，最后计算欧氏贴近度。结果表明：南宁市的欧氏贴近度大于Ⅲ级，说明其水资源承载力相对较低；钦州市、北海市，特别是防城港市的欧氏贴近度较小，水资源潜力较大。

Water resources bearing capacity evaluation method of Guangxi Beibu Gulf Economic Zone

Fuzzy matter-element model based on AHP was adopted to evaluate the water resources bearing capacity of Beibu Gulf Economic Zone.Based on analysis of the bearing capacity,main evaluation indexes constitute the fuzzy matter-elements;then all evaluation indexes and their corresponding fuzzy values constitute composite fuzzy matter-elements;the weighted factors of all indexes were determined by AHP method;Euclid approach degrees were calculated finally.The Euclid approach degree of Nanning City exceeds Grade I...
