ABSTRACT

In this study, the accessibility value of ports is obtained by using GIS cost-weighted distance method through Arcgis10.8 software; Secondly, construct a scientific and objective port competitiveness evaluation system, and use the original research data of 2012, 2016 and 2020, through SPSS factor analysis, calculate the comprehensive influence of the main ports in Jiangsu province in different years; Then, the shortest transportation distance between port and city is obtained through GIS network analysis; Thirdly, on the basis of comprehensive consideration of the industrial output value and permanent population of the city where the port is located and the industrial output value and permanent population of the potential city, combined with the optimal transportation distance of the port to the potential city, the correlation degree between the port and the city is calculated; Then, based on the introduction of Gaussian Plume Model, a Gaussian Plume Model suitable for port range division in Jiangsu Province is constructed; Finally, the scope evolution of port cities in Jiangsu province is analyzed, and the corresponding improvement suggestions are put forward.
