The construction of logistics parks in port areas will help to expand and improve port functions,providing robust support for industrial agglomeration and urban development.Through sorting out the current development status of logistics parks behind major ports in the country,it is found that some parks have problems such as unclear positioning,inadequate infrastructure,and ineffective coordination with port functions.Through the analysis of the causes of these problem,the key difficulties and countermeasures of the planning and layout of port logistics parks are identified.The basic methods of planning and layout are proposed from three aspects:park positioning,site selection,scale,and functional layout.Park positioning should be integrated with port development,industrial layout,and urban planning to achieve integrated development of port,industry,and park.The site selection should fully consider transportation conditions such as highways,waterways,and railways,with the aim of promoting multimodal transportation as the starting point.The functional layout should focus on the movement of goods in and out of the port,and consider factors such as surrounding relationships,transportation connections,and site conditions.The research results provide a reference basis for the planning and construction of port logistics parks,and take the logistics park in Xuwei Port Area of Lianyungang as an example.
