Problems solved by technology

However, with the continuous upgrading of port functions and the complexity of factors affecting the division of hinterland, the fierce competition of ports puts forward more refined requirements for the definition of hinterland; the continuous improvement of multi-modal logistics systems such as road-rail combined transport and river-sea combined transport , also has a new and important impact on the division of the port hinterland; and the high concentration of ports in the port group area has led to the emergence of a competitive hinterland with complex competitive relations

Abstract

The invention discloses a port ventral region division method based on GIS technology. The method comprises the following steps: obtaining related index data of all ports in a target region; carrying out a PCA principal component analysis on the related index data, and calculating a port strength Aj of each port; constructing a grid analysis map layer and a multi-modal transport network analysis map layer in a road mode in the target region, and comprehensively obtaining a transport cost distance Dij from any region i to any port j; substituting the port strength Aj of each port and the transportation cost distance Dij from any region i to any port j into a Huff model which is based on an abdominal region division to obtain a probability that a cargo owner of region i selects to go to the port j under the condition of an optimal transportation cost; substituting the probability into a Cullinane competitive abdominal region model, and outputting an abdominal region division result of all ports. The method enables the realization of a refined and modernized port abdominal region division and the technical solution is highly practical and widely applied.

Description

technical field [0001] The invention relates to the technical field of port planning, in particular to a method for dividing the hinterland of a port based on GIS technology. Background technique [0002] Nowadays, as the gateway of regional trade import and export, the port group is the basic support and reshaping force of the regional and even national spatial structure, and plays an important role in promoting the development of regional economy. The development of port groups will inevitably bring about the competition of cargo sources among the ports in the region, which is essentially the competition in the economic hinterland. In this context, clarifying the development status, scope and competitive relationship of the hinterland of the port will provide important support for the strategic decision-making of port investors, and will also support the rational planning and construction of port groups, reduce vicious competition in ports, and optimize capital and social ...
