Abstract: As the economic center in the north,the overall economic growth of Tianjin is swift and violent,especially the marine industry in Binhai New Area.Therefore,Tianjin local government has developed series of policies and plans related to ocean environment.Although these policies have made some sense to the pollution of the marine environment,due to the nearly enclosed sea of Bohai Bay and Tianjin is located in the western,exchange ability and pollutant diffusion ability of seawater in Tianjin area are extremely low.Therefore,the development of marine economy is inhibited by the marine environmental pollution heavily.It is necessary to enhance marine environmental protection efforts and marine ecological environment restoration technology.In this paper,the present situation environmental pollution of Bohai Bay Tianjin area was discussed,and then the pollution sources and type were analyzed.From the laws and policies which can be used in Tianjin area,we suggested a suitable management.Final,on the basis of existing restoration techniques,we discussed the restoration methods for marine environment in the Bohai Bay Tianjin area.
