基于GIS的黑龙江省市域交通可达性分析

City in Transportation Accessibility Analysis Levels in Heilongjiang Province Based on GIS

针对城市公路交通网络建设问题,本文以黑龙江省为研究区,地级市为研究单元,采用加权平均旅行时间作为指标进行空间插值,对黑龙江省市域交通可达性进行分析。结果表明:黑龙江省的交通可达性以哈尔滨市、大庆市、绥化市为中心呈同心圆状向外逐渐降低,其中,哈尔滨市与大庆市的加权平均旅行时间下降幅度较大,大兴安岭地区的加权平均旅行时间最大。不同市域的经济发展与人口总数也影响着市域的交通可达性,在注重经济发展的同时,也应注意交通网络的合理拓建。

Aiming at the construction of urban highway traffic network. This paper takes Heilongjiang Province as the research area,prefectural cities as research units,spatial interpolation using weighted average travel time as an indicator,analysis of the accessibility of the city area of Heilongjiang province. The result shows that traffic accessibility in Heilongjiang Province gradually decreases with concentric radiation from Harbin,Daqing and Suihua as the center,among them the weighted average travel time in Harbin and Daqing has decreased more,Daxinganling has the largest weighted average travel time. The economic development and the total population of different cities also affect the traffic accessibility of the city,while paying attention to economic development,but also should pay attention to a reasonable extension built transport network.
