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 transporta-tion 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 “regional convergence”and “urban differentiation”on different scales .Railway travel accessibility inside Guangdong Province existed serious spatial imbalances .The research would provide a ref-erence for the livable city construction .
