摘要
本文以丝路经济带为研究对象,结合目前比较成熟的GIS软件分析技术,基于丝路沿带国家现有铁路网中的每个国家部分行政省会城市抽象为铁路网络中的节点,以2018年各国及省会城市间铁路网的加权平均旅行时间距离为度量指标,直观、准确地对整个丝路沿带现有铁路网的时间通达性及空间格局进行测算和分析。研究表明:(1)整个研究区时间通达性在空间分布上极不均衡,最优的主要集中在东欧和中南亚地区城市;最差主要集中在中亚、西南亚地区城市。(2)整个研究区在不考虑本国家内城市之间的相互影响下,时间通达性空间格局发生了较大变化,但是整体空间分布仍旧极不均衡。
In this paper,the Economic Belt of Silk Road as the research object,combined with the current more mature GIS software analysis technology,based on the Silk Road along the belt of the country ’s existing railway network,the administrative provincial capital in each country part is abstracted as a node in the railway networks,between countries and provincial capitals in2018 the weighted average travel time distance as a measure,the time accessibility and spatial pattern of the whole Silk Road along are accurately calculated and analyzed with the existing railway network. The results showthat:(1) The time accessibility of the whole study area is very uneven in spatial distribution,and the optimal concentration is mainly in the cities of Eastern Europe and Central Asia;the worst is mainly concentrated in the cities of Central Asia and West Asia.(2) The spatial pattern of time accessibility has changed greatly in the whole study area without taking into account the interaction between cities in their home countries,but the overall spatial distribution is still extremely uneven.
