特大城市铁路客运枢纽与城市功能互动关系——基于节点-场所模型的扩展分析

伴随高铁时代的来临和城市快速扩张,铁路客运枢纽地区与城市功能的一体化发展面临新的机遇与挑战.基于节点-场所模型进行扩展,描述交通流重构、场所功能重组,以及三类地区的发展趋势.应用模型进行实证研究,分析新建铁路客运枢纽与既有铁路客运枢纽、既有城市中心之间的关系,探讨铁路客运枢纽和城市中心实现节点与场所平衡的路径.提出通过客流培育与长途功能疏解提升既有铁路客运枢纽的场所功能,通过耦合与直达提升既有城市中心的节点功能,同时完善新建铁路客运枢纽的节点与场所功能,从而实现铁路客运枢纽和城市中心的节点-场所平衡.

Interaction between Railway Terminals and Urban Functionalities in Mega Cities: An Extended Analysis Based on the Node-Place Model

With the arrival of the high-speed rail era and rapid urban expansion, the integrated development of railway terminal areas and urban functionalities are faced with new opportunities and challenges. Based on the extension of the node-place model, this paper discusses the reconstruction of traffic flow, reorganiza-tion of functional places, and the development trend of three types of regions. The paper applies the model in the empirical study, which analyzes the relationships between new railway terminals, existing railway terminals and city centers, and further discusses how to balance node and place functionalities between rail-way terminals and city centers. The paper proposes to elevate the place functionalities of railway terminals through passenger growing and long-distance transport mitigation and to enhance the node functions of ex-isting city centers through integration and direct accessibility. Meanwhile, the paper emphasizes improving both the node and place functionalities of new railway terminals so as to realize the node-place balance be-tween railway terminals and city centers.
