The Research Impaction Of Highway To Spatial Form And Spatial Structure Of City

Since the reform and opening up, China's rapid economic development, urbanization and modernization drive has been accelerated. City spatial form and spatial structure has undergone major changes. This rapid expansion of urban reform and opening up the opportunity, with China as the basic spatial extent of the central city to study in the context of city highways and summarize their morphology evolution was investigated highway on the impact of city spatial structure and layout of the land continuity. Hope that the "era of post-highway" city planning opportunities and challenges facing the intention to make a number of exploration.First, the history of Nanjing city form changes, for example, summarized the highway on the dynamic changes of city form. Then, through various cities in Hunan province's city construction land area of a mathematical model to analyze the morphological changes and land by the highway impact of structural adjustment, and summarizes the role of highway law. Finally, summarize the results of research on the "highway after the period of" city building of development proposals.On a city highway and city economic development in the region of great influence on city land use change has some impact, but this effect with other types of roads were different. Restricted mainly to the combined effect of force and attraction. Only on the highway and other roads connecting the city's location and the entrance was attracted to its direction of expansion of city land in other regions are not much gravity. The great advantage of the traffic interchange will help reduce the transaction costs of buyers and sellers against traffic advantage with market advantage, will translate into a good flow and economic advantages, bringing huge economic benefits. Near the highway junction is mainly in the industrial park land development trend of suburbanization trend in residential areas, shopping centers and distribution centers trends.Greatly reducing the Metropolitan Expressway built within the cities of the temporal and spatial distance, on the one hand, the market is strong, time-sensitive, high efficiency of the agricultural industry to bring greater opportunities for development, the corresponding change significantly the structure of land use, resulting garden, woodland increased reduction of arable land, agricultural land use structure has been optimized. On the other hand, industrial land has greatly increased. The enormous highway traffic and economic advantages to help reduce the transaction costs of buyers and sellers, plus transportation advantages into market advantage will be good for the circulation and economic advantages, making the commercial area along the sharply increased, especially in the vicinity of Interchange, forming a circle the size of business, bringing huge economic benefits, and good prospects for development.Highway as a city transport system, an integral part of the significant impact the city's planning and construction of internal transport and city space structure. Therefore, the analysis of highway within the context of city spatial form and spatial changes in the structure of great significance.
