Abstract: In recent years, there are many ecological environment problems happened in developing wetland environment. Because the combination of many development patterns and factors has cumulative effects on wetland environment, the environment assessment of simple element cannot meet the need of wetland protection and utilization. Therefore, it is necessary to emphasize the study on the cumulative effects of wetland environment. In this paper, the definition and content of wetland cumulative effects were developed, the spatial and temporal scope of these effects was identified, and the related study methods were reviewed. The deficiency of the current study was illustrated, and the directions for further study were put forward, including the path of environment cumulative effects, the long monitoring of the cumulative effects of wetland environment, and the construction of the prediction model of environment cumulative effects.
