摘　　要：介绍了熵和熵权的概念与性质,结合等效数值评价方法,对福州山仔水库富营养化进行综合评价,评价结果与物元分析模型、属性识别理论方法、模糊隶属函数法进行对比,结果表明,利用熵权等效数值法进行富营养化综合评价是可行的.Introducing the concept and character of entropy and entropy weight, the equivalent numerical method based on entropy weights was established, and applied the model for evaluating the eutrophication of Shanzi Reservoir comprehensively. Compared with the matter element model, the attribute identify model and the fuzzy administering function, the results indicate the equivalent numerical method based on entropy weights is viable for evaluating the eutrophication.

关 键 词：熵 熵权 等效数值法 富营养化 山仔水库
