山地城镇公交网络结构特征及空间机理研究

为挖掘山地城镇公交系统专项规划的科学原理,在城乡规划学和复杂性科学交叉领域,运用复杂网络分析原理和方法,选用重庆市主城区和成都市主城区分别为山地城镇和平原城镇对比样本,构建公交复杂网络模型,建立网络整体、局部和个体结构特征分析指标体系,揭示了公交网络在山地城镇空间形态约束下的“集聚-破碎”结构特征及其“地形阻隔”空间机理,为山地城镇公交系统专项规划与规划优化提供科学依据。

RESEARCH ON THE STRUCTURAL CHARACTERISTICS AND SPATIAL MECHANISM OF BUS NETWORK IN MOUNTAINOUS TOWNS

To explore the scientific principle of special planning of bus system in mountainous towns, complex network model of urban bus system have been constructed and evaluation index for analyzing the overall, local, and individual network structure characteristics has been set up in crossing fields of urban and rural planning and complex science, with adoption of the principle and method of complete network analysis, by selecting Chongqing and Chengdu as the comparative samples of mountainous towns and plain towns. "Agglomeration and fragmentation" structural features as well as "terrain barrier" composition mechanism of bus system complex network under the constraint of urban spatial form in mountainous area have been revealed, which provides scientific evidence for special planning and optimization of public transport system in mountainous towns.
