摘　　要：根据熵权法确定评价指标权重,利用物元分析方法对湖泊富营养化进行综合评价,评价结果与属性识别理论方法、模糊隶属函数法进行对比,结果表明,利用物元分析法进行湖泊富营养化评价是可行的。Entropy weight is used to calculate the weight of evaluating indicators,then a matter element model is also adopted to evaluate the eutrophication of lakes.The results are compared with those of attribute identifying model and the fuzzy administering function, the results indicate that the matter element model is feasible for evaluating the eutrophication of lakes.
