Abstract: In order to correctly evaluate wetland ecological benefit and restoration in the natural reserves of western Jilin Province, an index system of wetland ecological benefit assessment for nature reserves was established based on ecosystem service theory and catastrophe theory. Considering the diversity characteristics of ecological benefit, and consulting the research results of ecological benefit in study area in 2001, the analytic hierarchy process and entropy method were introduced to analyze the ecological benefit and restoration in 2005 and 2012. The results showed that the ecological benefit level was very high in Momoge Nature Reserve since 2005, high in Chaganhu and Xianghai nature reserves, and moderate in Dabusu Nature Reserve. This study showed that the assessment combining the catastrophe progression method with the analytic hierarchy process and entropy method could reveal the dynamics and the integrality of wetland ecological benefit, and accurately reflect the reality of the ecological restoration in study area. In recent years, some achievements in ecological protection and environmental remediation had been obtained in the west of Jilin Province, and the whole ecological benefit of the wetlands had been improved and enhanced by means of man-made effective interference.
