Zusammenfassung:	The invention discloses a method for evaluating the state of a water ecosystem. The method comprises the following steps: acquiring ecological indexes of a target lake; obtaining the membership degree of each ecological index under different water ecosystem state classification standards; carrying out comprehensive evaluation by combining the weight corresponding to each ecological index, and obtaining the comprehensive membership degree of the target lake under different water ecosystem state classification standards; and according to the comprehensive membership degree of the target lake under different water ecosystem state classification standards, evaluating the water ecosystem state of the target lake. According to the method for evaluating the state of the water ecosystem, a clear ecosystem comprehensive evaluation index system is established through the processes of index classification, index weight analysis, fuzzy comprehensive evaluation and the like, the objectivity, systematicness, comprehensiven
