The Bohai Rim region is exposed to environmental problems such as the degradation of ecological functions of estuarine and bay coastal wetlands，shoreline and beach erosion and human impact，siltation and pollution of the estuarine sea area，environmental deterioration of waterbody and bottom sediment，as well as land-based pollution. Through the practice of the coastal regulation and restoration project in the Bohai Sea area，this paper puts forward the coastal ecological restoration concept and preliminary work ideas suitable for similar projects，repair engineering measures，and expected repair effects by the analysis of induction and summarization. It is concluded that the purpose of restoring coastal types，controlling pollution，restoring wetland ecology，and enhancing regional hydrodynamic environment can be achieved through measures such as structure demolition，desilting，tidal creek dredging，vegetation restoration，and shoreline restoration. In this way，the goal of restoring coastal wetlands and shorelines can be achieved.
