摘　　要：交通运输工具深刻地影响着土地空间结构演化。在机动化出行方式由道路交通向轨道交通转变、城市功能区由中心城区向大都市区转变的背景下,本文以城市化历程较长、空间结构形态同我国特大城市接近的布宜诺斯艾利斯为实证对象,研究了不同制式轨道交通在空间结构演进中的作用。轨道交通对空间结构的影响主要体现在三个方面:一是有力地支撑了城市空间拓展;二是促成了“带”形城市走廊的形成;三是支撑了中心区居住人口密度的降低和商业、商务人口密度的提升。The means of transportation profoundly affect the evolution of the spatial structure of the land.In the con⁃text of the transformation of motorized travel mode from road traffic to rail transit,and the transformation of urban functional areas from central urban areas to metropolitan areas,this paper used Buenos Aires,which had a long ur⁃banization process and a spatial structure similar to that of China's megacities,as an empirical object,and studied the role of different rail transit systems in the evolution of spatial structure.The impact of rail transit on the spatial structure is mainly reflected in three aspects:the first is to strongly support the expansion of urban space;the second is to promote the formation of a"belt"-shaped urban corridor;the third is to support the reduction of residential popu⁃lation density and the increase of commercial and commercial population density in the central area.
