摘　　要：针对湖泊水质富营养化评价中各等级之间的模糊性,在充分考虑水质各污染因素权重大小的基础上,运用模糊综合评判方法建立了湖泊水质富营养化评价模型.并研究了我国5个主要湖泊的富营养化状况,和其它方法比较,取得了满意的结果.为湖泊水质富营养化评价提供了一种准确的、有效的决策方法.In the light of the fuzzy characteristic among grades of water quality nutrition evaluation in lakes and on the basis of fully considering the weights of water quality pollution factors, the water quality nutrition evaluation model of lakes was established by applying the fuzzy, composite assessment. The nutrition levels of five major lakes in our country were studied with a more satisfactory result compared with other methods. Thus, an accurate and effective decision method has been provided for water quality nutrition evaluation of lakes.
