摘要：通过分析城市空间结构的生长演化机制，研究城市空间结构与城市交通的互动关系。将城市空间结构的生长演化归纳为城市外部空间扩张和内部结构调整两个方面，指出二者均与城市交通的发展密切相关：外部空间扩张依赖于交通工具的改进和出行方式的转变，内部结构调整借助于相关区位交通条件的改变。论述了城市空间的生长演化与城市交通互动关系的核心是可达性，并由此论述城市交通发展和城市空间结构相互作用的机理。

Abstract：This paper explores the interaction between urban spatial structure and urban transportation by analyzing the evolution mechanism of urban spatial structure. With the evolution of urban spatial structure classified into external spatial expansion and internal structure adjustment, the paper reveals that the both parts are closely related with the development of urban transportation: the former depends on the renewal of means to travel and the change of travel modes, while the latter relies on the improvement of traffic conditions in related regions. The paper identifies accessibility as a key element that plays an important role in the interaction of spatial evolution and urban transportation, and further discusses the interaction mechanism.
