特大城市的多个中心区组成功能各异的中心体系,发挥了区域经济中心和服务辐射职能,轨道交通与其互动发展,形成相互作用,相互影响的关系。本文基于首尔中心体系的空间数据和演变拓展历程,结合城市轨道交通的发展过程,对首尔中心体系发展进行历史分期,理清首尔中心体系与轨道交通发展的内在关系。最后,结合国内外特大城市相关案例,归纳总结特大城市轨道交通发展与中心体系发展的互动特征,相互影响机制,以期对国内特大城市轨道交通规划与发展提供借鉴。 The metropolitan centers in various mega-cities form a central system with different functions, exerting the role of regional economic centers and service radiating functions and rail transit in their interaction and interaction and forming an interactive and mutually influential relationship. Based on the spatial data and evolution of Seoul Central System and the development process of urban rail transit, this article makes a historical installment of the development of central Seoul system and clarifies the relationship between central Seoul system and the development of rail transit. Finally, combining the relevant cases of mega-cities at home and abroad, this paper summarizes the interaction characteristics and interaction mechanisms between the metro development of metro cities and the development of mega-cities, with a view to providing reference for metro planning and development in mega-cities.
