For the ecological port construction measures in the overall planning of Taipingwan port area of Dalian Port，we carry out qualitative and quantitative analyses and mathematical model experiments to demonstrate two aspects. It is proposed that in terms of the marine ecological protection around the port area，we may take the measure of optimizing the planning of the port boundary and navigation channels and carrying out boundary demonstration for the protection of the agricultural and fishery areas，tourism and recreation areas，harbor seals，and national-level aquatic germplasm resources；in terms of the marine ecological protection inside the port area，we may take measures such as protection of water bodies，tidal channel and sluice gate arrangement，ecological shore protection and greening rate control，receding to wetness，and construction of permeable structures. It provides support for the optimization and implementation of the overall planning and provides references for marine environmental protection measures in similar planning.
