Firstly, on the basis of research background, the research content and map has been proposed, also, literature on the research field is reviewed, then, according to the principle of the index choice, the evaluation index system was established, and the corresponding weight of each index can be calculated by Analytic Hierarchy Process, still, the post evaluation model based on System Dynamics is proposed. Then, case study on Qilihai wetland protection and ecological restoration project in Tianjin is presented, according to Analytic Hierarchy Process, the value of the indexes is confirmed, based on the post evaluation model proposed, the case on Qilihai wetland protection and ecological restoration project is analyzed, which validates the method proposed is scientific and applicable. Finally, the dissertation is summarized and the future study is also proposed.
