摘　　要：针对湖泊水质评价中存在模糊性的特征,应用可变模糊集理论建立湖泊水质评价模型.模型以相对差异函数为基础,充分考虑评价指标的"优"与"劣"两方面,更具合理性.利用可变模糊集方法对杭州西湖、青海湖、巢湖以及滇池的水质进行评价,并对样本进行排序.实例表明该模型简单方便、有效可行,能较好地应用于生产实际.Considering the fuzzy feature in assessment, evaluation model based on variable fuzzy sets that can consider the good and bad character of indexes is established. The method is developed to evaluate water quality of lake in West Lake, Qinghai Lake, Chao Lake and Dianchi Lake, and the results show that new evaluation methods is feasible and can effectively evaluate water quality of level.

关 键 词：湖泊水质评价 可变模糊集 综合评判
