东北地区港口腹地空间演变研究——基于考虑港口支持度的Huff模型

Study on Spatial Evolution of Port Hinterland in Northeast China——Based on Huff Model Considering Port Support

考虑港口功能的转变,文章引入港口支持度指标体系对Huff模型进行改进,对辽宁省港口群在东北三省的腹地范围进行定量划分,并运用Arcgis软件制成直接腹地与混合腹地地图分析腹地格局空间演变。结果表明:大连港的腹地范围在不断扩大,其余港口腹地范围在不断缩小。2017年大连港的直接腹地为吉林省全境、黑龙江省全境以及大连、铁岭、抚顺、本溪、沈阳;营口港在辽宁省内势能最高,直接腹地为营口、鞍山、辽阳三市;锦州港的直接腹地为辽西朝阳、阜新、锦州三市;丹东港、盘锦港、葫芦岛港直接腹地仅为港口所在城市本身。丹东港在通化、白山两市势能较高,盘锦在辽宁省北部城市有一定影响力。自然区位条件、交通可达性、港口城市经济因素是影响港口势能以及港口腹地空间演变的三个重要因素。

Considering the change of the port function,this paper introduces the port support index system to improve the Huff model,quantitatively divide the hinterland range of the Liaoning port group in the three northeastern provinces,and use Arcgis software to make direct hinterland and mixed hinterland maps to analyze the hinterland pattern space evolve.The results show that the hinterland of Dalian port is continuously expanding,and the hinterland of the remaining ports is continuously shrinking.In 2017,the direct hinterland of Dalian port is the whole territory of Jilin province and Heilongjiang province and Dalian,Tieling,Fushun,Benxi,Shenyang;Yingkou port has the highest potential energy in Liaoning province,and the direct hinterland is Yingkou,Anshan,and Liaoyang;The direct hinterland of China is Chaoyang,Fuxin and Jinzhou in western Liaoning;the direct hinterland of Dandong port,Panjin port and Huludao port is only the city where the port is located.Dandong port has higher potential in Tonghua and Baishan,and Panjin has a certain influence in the northern cities of Liaoning province.Natural location conditions,traffic accessibility,and port city economic factors are three important factors that affect the port potential and the spatial evolution of the port hinterland.
