摘　　要：我国省会城市多处于铁路枢纽,研究省会城市的铁路通达性,对于调整列车运行图方案、改善旅客出行体验、优化铁路网布局、指导远期线路规划建设都具有重要意义。对既有的城市通达性度量方法及其适用性进行分析,结合我国铁路网发展格局和态势,提出一种新的省会城市铁路通达性度量指标—省会城市铁路通达性指数;利用中国铁路客票发售和预订系统(简称:客票系统)历史数据,对2012~2021年我国省会城市的铁路通达性变化情况进行全面、深入的分析,探讨各时段省会城市铁路通达性变化的原因及趋势,精准识别在铁路通达性方面与相邻省会城市存在明显差距的省会城市,从线路规划建设和列车运行图调整方面提出改进建议。Most of China’s provincial capitals are located in railway hubs.The study of railway accessibility of provincial capitals is of great significance for adjusting train operation plans,improving passenger travel experience,optimizing railway network layout and guiding long-term route planning and construction.Based on the analysis of the existing urban accessibility measurement methods and their applicability,a new railway accessibility index for provincial capitals is proposed based on the development pattern and situation of China’s railway network.Using historical data from the passenger ticketing system,a comprehensive and in-depth analysis of the changes in railway accessibility of provincial capitals in China from 2012 to 2021 is conducted,the causes and trends of the changes in railway accessibility of provincial capitals in each period are explored.Meanwhile,the provincial capitals that have a significant gap with their ineighboring provincial capitals in railway accessibility can be accurately identified and suggerstions for improvement are put forward from the aspects of ralway line planning and construction as well as train diagram adjustment.
