摘　　要：深入探讨铁路可达性与城市活力的协调发展关系,有助于城市群可持续发展和区域均衡发展。运用熵值法评估城市活力,并利用加权平均旅行时间来分析铁路可达性的时空演变特征,同时,应用耦合协调度模型和空间计量模型,研究城市群铁路可达性与城市活力的耦合协调关系及铁路可达性对城市活力系统的影响。研究结果表明,关中平原城市群的城市活力整体呈上升趋势,铁路可达性明显提升,形成了典型的“核心-边缘”空间格局,城市活力与铁路可达性的耦合协调度呈现出明显的地域差异,铁路可达性对当地及城市群的经济活力具有促进作用,但对周边地区的经济活力存在反向效应。此外,铁路可达性有助于提升本地及周边地区的社会活力,并对当地的环境活力产生正向影响。In-depth exploration into the coordinated development relationship between railway accessibility and urban vitality is conducive to the sustainable development of urban agglomerations and balanced regional development.This paper employs not only the entropy method to assess urban vitality but also the weighted average travel time to analyze the spatial-temporal evolution characteristics of railway accessibility.Meanwhile,the coupling coordination degree model and spatial econometric model are adopted to investigate the coupling and coordination relationship between railway accessibility and urban vitality in urban agglomerations,as well as the influence of railway accessibility on the urban vitality system.The results indicate that the urban vitality of the urban agglomeration in Guanzhong Plain exhibits an overall upward trend with significantly improved railway accessibility,which leads to a typical“core-periphery”spatial pattern.Additionally,there are notable regional differences in the coupling coordination degree between urban vitality and railway accessibility.Specifically,railway accessibility can promote the economic vitality of local areas and urban agglomerations,but it exerts a reverse effect on the economic vitality of surrounding regions.Furthermore,railway accessibility contributes to enhancing social vitality in both local and surrounding areas,having a positive effect on the environmental vitality of the local area.
