Study On The Port Group Hierarchy Layout Of Liaoning Province

With the continuous development of economic globalization, the international logistics trade becomes more and more frequently. The amount of goods is increasing every year, and many countries open up new routes. This brought about a period of great development of the port; the port has slowly transformed the simple role which is loading and unloading cargo into the role of active trade positions. Governments have also introduced policies to encourage the construction of port facilities. It will promote the economic development of the port and the hinterland. But conduct port construction will also bring some problems, such as ports redundant construction, port misalignment, ports scattered layout. So we need the hierarchical layout of the harbor.This article gives some overviews and summaries of the layout of ports and port-related theoretical knowledge, a clear understanding of the trends and characteristics of the port. Then regional port cluster layout, analysis of the various factors that affect the distribution the level layout analysis model combined with fuzzy clustering method of ports, establish the evaluation index system.Last article detailed description of the major coastal ports in Liaoning Province, and port-level layout model above establish fuzzy clustering instance validation. I select the port of Dalian, Liaoning Province, Yingkou Port, Jinzhou Port, Dandong Port, Panjin PortHuludao Port, Port Arthur, Zhuanghe port to give them hierarchical layout. And the result is that Dalian is the first level of the port, Yingkou and Jinzhou port of the second level, and the rest of the conclusion of the third-level port. The conclusion to other parts of the regional port cluster integration can provide a reference, but resources building ports provide the basis for Liaoning Province to implement coastal economic zone integration.
