Pinglu Canal starts from Pingtang River Estuary,a tributary of the Xijin hub reservoir in the upper and middle reaches of the Xijiang shipping trunk line,and ends at Beibu Gulf Port.It is a networking project that optimizes and enhances the national water transportation network and accelerates the construction of a national comprehensive three-dimensional transportation network.It is a landmark project for building a new land-sea channel in the western region and accelerating the construction of a strong transportation country.According to the deployment of National Comprehensive Three-dimensional Transportation Network Planning Outline,the overall plan for Beibu Gulf Port is currently being prepared,and it is necessary to comprehensively consider the spatial layout and plane layout of river-sea intermodal transportation hub of Pinglu Canal.This paper comprehensively considers the river-sea intermodal transportation volume of Pinglu Canal,the construction conditions and resource capacity of each port area in Beibu Gulf Port,as well as the utilization of existing port resources.Based on the principle of “nearby transportation and sufficient stock”,a river-sea intermodal transportation hub layout is proposed according to local conditions,with a plan for matching the capacity of large and small berths and efficient transportationorganization.At the same time,it also proposes to clarify the division of the navigation area of Fangchenggang,study the opening of Fangchenggang Water Transport and Port Dredging Channel (Huangcheng'ao Canal),and orderly promote the upgrading and renovation of existing docks,so as to provide technical support for the smooth operation of river-sea ntermodal transportation after the construction and operation of Pinglu Canal.
