| This research mainly through the study of ChangBai mountain region highway network distribution characteristics and spatial expansion and shorten time to study the features, such as urban areas and the changes of the network structure, and puts forward some Suggestions.Due to the highway is the region's primary towns connection means of transport, therefore, the study on the highway research static and dynamic characteristics, main uses the method of literature, matrix analysis, GIS spatial analysis method and topological analysis, etc. Using matrix analysis of urban network of clear, Using the method of topological analysis of urban network connection, GIS spatial analysis principle applies all data processing and analysis in the process of maps. In the study, mainly using dynamic traffic "quantity", which helps us understand the evolution of spatial structure of urban areas and the law of development.hrough this research can draw the following several aspects of the conclusion.Changbai mountain area highway, first of all, XiangXiang channel "to" basic level, with east-west and south-north in national highway, forming dentrites highway. Since the reform and development of changbai mountain region highway experienced two aspects, namely, the process of the expansion of space on highway time and distance shortened. To build a new highway to promote the highway spatial expansion, and improve the relationship between the town, but the little change. The development of network depends largely on time on the distance shortened. Along with the average speed in the cities, the people and between logistics is growing, and improve the connection between the town.Secondly, on the whole, the town of scale formation in changbai mountain area pyramid structure. And the size distribution of changbai mountain region close to first distribution. In the distribution of urban geographical position, due to reasons such as politics, economy, population and the town is northwest and southeastern than other regions centralization, Changbai mountain region in the town of network structure to grid type change spine type of process. According to the shortest path and the shortest time analysis of urban areas of changbai mountain, prudent results of changbai mountain region in baishan area clear town of some of the town, the central region to the surrounding areas, the clear, Compare changbai mountain region in 1998 and the contact intensity in 2007, we can draw the Yanji and TongHuaShi core position more prominent, and surrounding towns radial network forming. In the bus, the number of operation of contact with Yanji and TongHuaShi mainly concentrated, especially for the center of the strength of the subprime Yanji contact center position. On the whole, though Yanji core position to rise gradually, but the core status of tonghua decline.The last, the analysis of relations between road transport network and urban development, Derived form graphical analysis that the level of urbanization and the development of highway network is Positive relationship. Urban development and road transport development are mutually reinforcing. Urban development will always be evolving, the same to the Road Traffic and Spatial Structure, because it is a comprehensive characterization in the period of time urban geography, socio-economic, and related policies at all levels.The significance of this study is to clear link between the towns and urban network structure characteristics in Changbai Mountain region. However, because of the limitations for analytical methods and data collection in Changbai region, only analysis the characteristics of the road network, don't analysis the air, rail and other transportation facilities. It only analyzed demographic and economic indicators when studied the process of urban development and their characteristics. Therefore, as a whole can't reflect more comprehensive urban network characteristics.
