模糊物元模型在评价区域水环境承载力中的应用

基于区域水环境承载力的模糊性以及评价指标的多样性，在分析湖州地区水环境承载力时，以模糊物元分析和层次分析法为基础，结合欧氏贴近度概念，用水环境代表事物，评价因素代表特征，建立了复合模糊物元矩阵，对水环境承载能力进行综合评价与排序。根据湖州地区的相关统计资料，建立了水环境承载力评价指标体系，分析了湖州近几年以及将来的水环境承载力变化趋势，得出该地区水环境承载能力与生态市目标还有一段距离，并与其它方法加以比较，进一步说明模糊物元分析法更具有可信度。

Application of Fuzzy Matter-Element Model to the Water Environmental Bearing Capacity

In order to evaluate the bearing capacity of water environment in Huzhou,this paper introduces fuzzy matter-element model and AHP method,combines with the concept of Euclid approach degree,regarding the water environment as the object of matter elements and the evaluation factors as character,and constructs the compound fuzzy matter element.Based on the stat datum of Huzhou,this paper constitutes the evaluation index system and analyzes the water environmental bearing capacity trend of Huzhou,then elicits that the water environmental bearing capacity of Huzhou still has a gap from that of the zoology city objective.Compared to other method,it can be concluded that the application of fuzzy matter-element model method for evaluating region water environment is feasible and reliable.
