[Objective]The study aimed at assessing the state of lake health. [Method]Based on the concept of " healthy lakes" analyzed deeply, the fuzzy integrated evaluation was used to establish the evaluation index system of lake health,and the analytic hierarchy process (AHP) combined with expert evaluation method was used to determine the weight of each indicator. Afterwards,the health state of three typical lakes (Sanbaidang,Beimayang and Qiaobeidang) in Wujiang City were evaluated by the system,and the measures to develop and protect the lakes were put forward finally. [Result]The assessment results showed that Sanbaidang and Beimayang were in basic health,while Qiaobeidang was in subhealth. The indicator system and assessment method are suitable for the rivers in eastern plains of China. [Conclusion]The research could provide scientific references for the development,protection and restoration of lakes.
