摘　　要：基于传统的逼近于理想解的技术,根据水环境质量的富营养化程度和待评价的水环境质量检测点(评价方案)的不理想(负理想)与理想(劣与优)这些典型的模糊概念,提出了基于模糊集合的逼近理想解法(TOPSISFS),并应用于水环境质量综合评价。TOPSISFS与模糊神经网络法、投影寻踪模型法、理想区间法相比,简单、有效,可广泛应用于多目标决策。According to the typical fuzzy concepts, such as eutrophication level of water environmental quality and the unideal （negative ideal） and ideal （superior and inferior） water quality stations （evaluation schemes）, a technique for order preference by similarity to ideal solution （TOPSIS） based on fuzzy set was presented and was used in the comprehensive assessment of water environmental quality. The result shows that the TOPSIS is more convenient and effectine than fuzzy neural network method, projection pursuit （PP） method and ideal interval method. It can be widely used for multi-objective decision.
