Research On The Interaction Between Urban Expressway Network And Urban Spatial Form In Nanning City

Urban expressway network is an important carrier of urban construction and development.From the domestic and foreign urban expressway network construction history and the basic theory of urban spatial form we can know that there is an interaction of some kind of mutual influence and restriction between the structure of urban expressway network and urban spatial form.Studying this internal relation will be a positive guiding significance to the planning of urban expressway network,also will be very helpful to the urban construction and development.The paper starts with characteristics of urban expressway network,analyzing the applicability of different urban expressway network forms in different cities,then puts forward the view that there is mutual influence between the urban expressway network and the urban space form.Take urban expressway network of Nanning City for example,through the formation and evolution history of the urban express ring road in Nanning City,and the demonstration of the relationship between the land development near expressway and the urban express ring road in Nanning City,the paper analyse the role of the urban expressway network in urban development and urban morphology of Nanning City,then on this basis the paper analyse urban expressway network suitable for the evolution of urban spatial form in Nanning,finally the paper put forward a layout scheme of the urban expressway network which can adapt to and guide the new urban spatial form of Nanning.
