新疆维吾尔自治区铁路路网扩张时空关系研究

Research on temporal-spatial relations of railway network expansion in Xinjiang

新疆维吾尔自治区是丝绸之路经济带三大通道的重要交汇地,是衔接亚太与欧洲的重要节点和枢纽,在丝绸之路经济带建设中发挥着重要的通道作用和桥头堡作用。但目前新疆地区铁路网密度整体较低,路网结构不够合理,南疆地区不少地方未通铁路,进出疆通道单一,这些短板不利于新时期新形势下丝绸之路经济带的建设。基于GIS技术,以不同时期新疆地区铁路网密度、人口密度和GDP密度为研究对象,分析路网发展与GDP、人口的时空关系,建立新疆地区铁路路网需求函数模型,对新疆在适应丝绸之路经济带核心区建设所需的路网密度和铁路建设量进行预测,为该地区铁路建设提供有效的决策支持。

Xinjiang,a meeting place for the three major thoroughfare of the Silk Road Economic Belt,is a vital node and hub linking the Asia Pacific region and Europe,which plays an important channel and bridgehead role in the construction of Silk Road Economic Belt.However,the low overall density of railway network in Xinjiang,the irrational railway network structure,no railway accessing to many parts of South Xinjiang and a single channel to Xinjiang are not conducive to the construction of the Silk Road Economic Belt in the new period and the new situation.Based on the railway network density,population density and GDP density from different periods in Xinjiang,the temporal-spatial relations among railway network development,GDP and population are analyzed.The demand function model of railway network in Xinjiang is established to predict the railway network density and railway construction needed by Xinjiang to adapt to the construction of the core area of the Silk Road Economic Belt,which can provide decision support for railway network construction in Xinjiang.
