摘　　要：为应对我国城镇化进程中城市建设逐渐由平原转向山区的发展趋势,探讨城市建设总体层面不同地貌下山地城镇道路规划的关键问题,并提出契合地貌特征的山地城镇道路系统综合设计方法。通过对西南山地地貌形态进行梳理,将其划分为槽谷、岭脊、沟梁、丘状四大类型。以山地地貌特征为依据,探讨顺应现状地貌条件的城市总体层面道路系统规划设计方法,并提出槽谷地貌应分离带状枝杈式布局的干路职能、岭脊地貌应调节立体圈层式布局的出行分布、沟梁地貌应强化蛇形曲尺式布局的系统联系、丘状地貌应疏解自由格网式布局的中心拥堵四种与地貌特征相对应的城镇路网结构组织模式。选取西南山地典型城镇规划案例,从路网结构与城市形态的呼应、交通组织与城市功能的协调、道路布线与城市景观、生态系统的营造等方面提出契合地貌特征的山地城镇道路系统综合规划策略。The paper discusses the focus of road planning in different mountainous towns from the general view and proposes comprehensive design methods for the road systems in mountainous towns corresponding to the processing of urbanization and sustainable development in a country with great pressure in space and resources. First of all, the paper divides the common landforms in the southwest mountainous regions into four types, trough valley, ridge, ravine and hill, and then presents each type g being causes, distribution and characteristics. Secondly, based on the classification of typical topographic features, the paper briefly present some road system planning methods for mountainous cities, which are overlapped functions of stripped and forked arrangement and skeleton roads in trough valley cities, three-dimensional circled layout and uneven city trip distribution in ridge cities, snake-zigzagging lay- out and weak systemic and overall connection in ravine cities, free-gridded layout and traffic jams at central sections in hill cities. Last but not least, taking comprehensive planning design strategy traffic organization, coordinate with the eco-system creation. the cases of mountainous cities in south-west China, the paper puts up a in the following interacting aspects, road structure plan, line selection, city structure construction, function organization, landscape shaping and
