西南山地高密度城市的空间结构与交通系统互动关系研究

The Mutual Relationship Between Urban Spatial Structure and Transportation System in Southwest High-density Mountain Cities

西南山地城市地形地貌复杂、建设用地紧张、旧城人口密集。由于自然地理条件的限制,长期以来形成了高密度的城市发展模式。从高密度城市的概念出发,分析了西南山地城市的高密度发展特征及原因,研究了西南山地城市在高密度发展影响下,城市规模、密度、功能布局等因素对交通系统的影响,以及交通方式、交通可达性和交通设施等因素对空间结构的影响。在此基础上提出西南山地高密度城市的空间结构和交通系统之间的互动影响机制,试图揭示高密度城市的一些发展规律。

Southwest mountain cities are characterized by the complex topography, city construction land shortage, and large population and so on. Restricted by physiographic condition, the high density development mode is formed. Based on the concept of high density city, this paper analyzes the high density development characteristics of southwest mountain cities and the reasons for its formation. In the context of the high-density development of southwest mountain cities, this paper analyzes the inlfuence of city scale, density, functional layout and other factors on the transport system, and the influence of transportation means, accessibility and facilities and other factors on the urban spatial structure. And on this basis, the paper puts forward the interactive mechanism between the urban spatial structure and the transportation system in southwest high-density mountain cities, and attempts to reveal the development law of high density city.
