内蒙古交通网络结构特征与城镇空间关联研究

Spatial structure of traffic network and spatial interaction of cities and towns in Inner Mongolia

交通网络是反映城镇联系和结构的重要途径。文中基于内蒙古公路、铁路、航空的客运班次数据和复杂网络分析方法,在对交通网络结构解析的基础上,探讨分析城镇相互作用关系,提炼城镇关联模式。结果表明:1)交通网络下的内蒙古表现为核心城市和重要节点城镇指向性。2)公路网络具备空间邻近和属地特征,局部范围呈现带状集聚模式。铁路网络以呼包银-集通线为发展轴进行延伸扩展,航空网络以呼和浩特的对外联系为主。3)各个交通网络具有小世界效应,但关键性城镇节点影响作用有限,网络化发育不完善。4)公路、铁路、航空网络下的城镇联系模式分别凝练为单核-多点分散型、轴线型、轴-辐型,显示出内蒙古内外联系的空间组织形式。研究结果为内蒙古交通体系优化和区域布局完善提供科学参考。

In the paper,the passenger traffic data of highways,railways,and aviation of Inner Mongolia and complex network analysis methods were used to analyze the spatial structure of traffic network and spatial interaction among cities and towns in Inner Mongolia.The results show:the concentration effect of core cities and important node towns is significant.The highway network has the characteristics of spatial proximity and territoriality,and the local area presents a belt-like agglomeration pattern.The railway network takes Hohhot-Baotou-Yinchuan-Jining-Tongliao line as the development axis.The internal and external connections of Hohhot is the general form of aviation network.Each traffic network has a small-world effect,the impact of key urban nodes is limited,and network development is not perfect.“Single-core and multi-point”mode is a typical representative of highway network.“Axis-spoke”mode is a typical representative of railway network.“Hub-spoke”mode is a typical representative of air network.The research provides a scientific reference for the optimization of transportation system and improvement of regional layout in Inner Mongolia.
