The New Concept of Fifth Generation Port and Navigation Engineering

Abstract

This paper puts forward the concept of port and navigation engineering of the fifth generation. Starting from the concept of port, it points out that port has gone through the change from the first generation port to the fourth generation port, and now it has entered the stage of the fifth generation port. The main functions of the fifth generation port include the functions of the previous four generations, while it also focuses on the combination of port city and port town, and its main characteristics are efficiency, ecology and low carbon. Then it puts forward the concept of ecological port and navigation in narrow sense and broad sense. In the narrow sense, the ecological port and navigation refers to the ecological port of the fifth generation port above the third and fourth generation ports and the ecological channel centered on the ecological port. In the broad sense, ecological port and navigation refers to the port and navigation system that combines ecological port, ecological channel, ecological port city and ecological village. The fifth generation port and navigation engineering is the port and navigation engineering corresponding to the fifth generation port, ecology is its most important feature, which is the new promotion of port and navigation engineering concept.
