| 摘 要： | 本文将湖泊富营养化的所有评价参数对于每一富营养评价等级的隶属度视为评价参数论域■2{x1,x2,…,xm}上的一个模糊子集。并通过计算和比较这些模糊子集的模糊度大小给出湖泊富营养化状态的评价等级判断。该方法应用于全国16个主要湖泊库的富营养评价结果,与用统计评分法作出的评价结果基本一致。

| Abstract: | In this paper, the subordinating degree of all assessment parameters of eutro-phication of lake to each eutrophication assessment grade is taken as a fuzzy set of the discourse field Ω of assessment parameters. The assessment grade of eutrophication state of lake is given by calculation and comparison of the fuzzy degree values of these fuzzy sets. This method has been applied to the eutrophi-cation assessment of 16 main lakes and the results comciue with that of the statistical method. |
