试论城市地貌环境与城市道路系统的关系*——以四川省几个城市为例

本文分析了城市地貌环境对城市道路系统的影响,认为地貌过程不仅影响了城市道路的建设和管理,而且是城市道路系统布局和发展的重要控制因素。以四川省几个城市为例,分析了山地城市、丘陵城市和平原城市道路系统的不同特点。

AN APPROACH TO THE RELATIONSHIP OF THE URBAN GEOMORPHOLOGICAL ENVIRONMENT AND URBAN ROAD SYSTEM-TAKING SEVERAL CITIES IN SICHUAN PROVINCE AS EXAMPLES

This paper analyses the influences of urban geomorphological environment on the urban road system and holds that the relief volume and dis seeted degree of surface and geomorphological processes change the construction cost of urban roads, and they control the layout of the urban road syste m in a certain extent.Taking several cities in Sichuan province as examples, the author analyses characters of urban road system in mountains, in hills and in plains, and approaches to the effects of various types of urban geomorphological environment in the forming and evolvement of the urban road system.General-ly speaking, in mountains and in hills, urban geomorphological environment has a great relief, more dissected surface and more active processes, so it gives clearly effects to the urban road system.In plains, urban geomorphological environment if favourable to the construction of roads, so the urban road system mainly reflects needs of urban traffic, transport and layout.
