Abstract: Marine ecosystem is one of the most valuable resources and relied by more and more coastal residents. Mangrove, coral reef and seagrass bed, in particularly, have high biodiversity and productivity, provide places for spawning and breeding and protect coast from wind and wave erosion. Along with economic development and human being’s activity, these marine ecosystems have been destroyed and then the restoration is needed. In this paper, the characteristics of the 3 marine ecosystems are introduced. Eco-restoration contents, methods and problems of these 3 typical and fragile ecosystems are also reviewed. At last, an universal restoration model and measures are proposed and summarized. The restoration should be considered consistently in the future. This method can be used as reference for the restoration of similar marine ecosystems in other areas.
