With the continuous advancement of green port construction,management requirements for coastal wetland protection and intensive sea use are becoming increasingly stringent at the national level,the systematic integration of the ecological sea use concept into port planning remains inadequate.In view of above problems,we explore the integration of the ecological sea use concept throughout the entire process of port planning and construction,proposes its active incorporation into key aspects of overall port planning such as spatial selection,overall layout planning,and coordination of construction environmental factors.Taking the Dongjiakou port area of the Qingdao Port master plan as an example,we focus on applying the ecological sea use concept during the port planning stage while ensuring the rationality of the port area plan and meeting development needs.Key measures include avoiding environmentally sensitive areas,implementing land-sea coordination and intensive sea use strategies,and optimizing the design of the port area layout,tidal channels,and ecological revetment structures.These efforts aim to achieve a balance between development and ecological conservation.
