基于区位几何要素的省域副中心城市铁路出行便捷性分析——以广东省湛江市为例

Convenience Analysis of Rail Travel in Sub-central City of Province Based on Location Geometric Elements: Taking Zhanjiang City in Guangdong Province for Example

采取实证研究的方法,选取邻近中心性、市内交通可达性、国内出行可达空间3个指标,探讨湛江市民基于铁路出行的便捷性。结果显示:(1)湛江站和湛江西站的邻近中心性表现出明显的"重心—边缘"模式。(2)湛江站的市内交通可达性高于湛江西站,且2个站点呈现不同的梯度空间分布格局。(3)省外出行可达空间在不同尺度上存在"区域趋同"与"城市分异"并存的现象,省内出行可达空间则出现了严重的"空间失衡"。

Taking empirical research methods, selecting three indicators of central adjacent, city transportation accessibility and domestic travel space, this paper discussed public convenience of rail travel in Zhanjiang, Guangdong Province. The results showed that the adjacent centricity of Zhanjiang railway station and Zhanjiang west railway station showed obvious ＂ gravity-edge＂ mode. The city traffic accessibility of Zhanjiang rail station is higher than that of Zhanjiang west rail station, and two railway passenger transportation sites presented different gradient space patterns of different quality. As traveling outside Guangdong Province on railway, citizens’ behaviors ap-peared coexistence phenomenon of u regional convergenceand u urban differentiationon different scales. Railway travel accessibility inside Guangdong Province existed serious spatial imbalances. The research would provide a reference for the livable city construction.
