In view of the adjustment of the general layout of Taipingwan port area of Dalian Port，we optimize the scheme by qualitative and quantitative analysis and comparative study method according to the macro environment change and the development requirements in the new period. The total area，sea area，occupied natural shoreline，and number of berths are reduced，while the capacity，greening rate，and the wharf shoreline are increased，which significantly reduces the impact on the ecological environment and improves the degree of wharf specialization.
