Pinglu Canal is a large river and sea combined transport，and it is an important part of the new western land and sea passage. Based on the analysis of the construction opportunity of Pingland Canal and the investigation of the current situation of Jiang-sea combined transport in the Beibu Gulf，this report comprehensively analyzes its strategic significance. The Pingland-land canal planning is conducive to the new pattern of river-sea combined transportation in Beibu Gulf，the coordinated and integrated development of Beibu Gulf region，the leapfrog development of coastal and port-adjacent industries，and the deep participation of Beibu Gulf region in the new western land-sea passage and the “Belt and Road” strategy. Beibu Gulf should seize the opportunity of the construction of Pinglu Canal，a new land-sea passageway in the west，plan the challenges and opportunities of the layout of the new pattern of Jiang-sea combined transport，and draw lessons from the typical cases of Jiang-sea combined transport at home and abroad to plan the layout of the new pattern of Beibu Gulf combined transport. Therefore，Beibu Gulf should adopt the “big opening” pattern，pay attention to the “big project” construction，do well in the “big supporting system”，promote the “big logistics” project，improve the connotation of “big service”，form the “big cooperation” mechanism and so on.
