【摘要】 模糊物元分析能很好地解决不确定性和不相容问题,水库富营养化是一种多元复杂的模糊系统,在模糊物元理论的基础上,结合欧氏贴近度的概念,利用三标度层次分析法确定权重,建立了水库富营养化评价的模糊物元分析模型。将此模型用于广东省20个大型水库富营养化评价,并将评价结果与综合营养状态指数法和灰色聚类法评价结果进行比较,有19个水库评价结果的差异小于等于一个级别,评价方法简单,评价结果可靠,具有一定的实用性。更多还原

【Abstract】 In view of uncertainty and complexity of the index for the reservoir eutrophication,a fuzzy matter-element method is applied to resolve such problems.In this paper,the fuzzy matter-element analysis,which is combination with Euclid closeness degree and AHP,is used for the reservoir eutrophication evaluation.The fuzzy matter-element method,together with the synthesis index of nutrition state method and the grey clustering method,has been tested by the measured data of 20 large reservoirs in Guangdong province in 2006.It is found that the difference of assessment results among those three methods is very closed each other.It indicates that the fuzzy element-matter method is simple,reasonable and practical in reservoir eutrophication degree evaluation.更多还原
