The evaluation of the effect of ecological restoration project is studied in this paper. Taking Qilihai wetland as a case, a comprehensive evaluation model based on System Dynamics (SD) is proposed. Firstly, the evaluation index system is established according to the actual situation of the wetland ecological restoration project, and the weight of each index can be calculated by Analytic Hierarchy Process (AHP). Then the simulation model based on SD is constructed, so the value of each evaluation index before and after the implementation of the project can be obtained. Finally, the comprehensive evaluation index before and after the project can be obtained with the weighted average method. The results show the model is effective and applicable
