Mountain City Interaction Between Transport And Land Use Study

The interaction between urban traffic system and land utilization has always been a hot research topic of urban geographers, urban planners and urban transport planners. In recent years, owing to development of economy day by day, the process of urbanization and mechanization accelerate continuously in China, especially more developed eastern coastal areas, the urban traffic problems are arising everyday, and more people pay attention to the interaction between urban traffic system and land utilization. Many experts and scholars have surveyed and explored details of above-mentioned problems and researched the interaction between urban traffic system and land utilization deeply in the quantitative and qualitative aspects. However, along with constant launching of China's western development strategy, similar problems of eastern areas emerge gradually in more and more western cities at the same time of the economy process. Though most of the Middle Western cities located in the first and second relief stages, are mainly on mountain highlands, the problems here have their own features, different from ones in eastern areas. Under such conditions, It appears very important to handle the highlands urban cities problems by deep study of the interaction between urban traffic system and land utilization.This paper takes the typical mountain city-Chongqing as sample to deeply study the urban traffic system and land utilization in main urban area of Chongqing. Firstly, analyze the dynamic changes between main urban area traffic system and land utilization, find out the more and more completeness of urban traffic system during constant development and the features of high density exploiture of land utilization. Then, represent the interaction between these two aspects respectively, on the one hand, the innovation of urban traffic modes accelerates the urban area extension, the development of urban traffic system plays a big role in the change of urban spatial relationship and land utilization in industry, business and resident etc. On the other hand, urban area scale, spatial relationship, overall plan and high density construction all affect the urban transport systems profoundly.Finally, based on the above problems and the contradictories between urban spatial relationship and traffic modes, between urban spatial pattern and backward road net, between less traffic land use and high density traffic, the paper proposes the strategy by using the "BRT+Light Rail" type TOD land exploitation mode to solve the urban problems in main urban area of Chongqing.
