Analysis of the Optimization of Nanchang Urban Spatial Structure Relies on the Construction of Subway

With the development of urbanization and the expansion of urban scale,rail transit plays an important role in solving the urban traffic problems and changing the urban spatial structure.Based on the analysis of the theory that the interactive development of urban land use and rail transit build the urban spatial structure and according to the status and planning of Nanchang urban spatial structure,Nanchang will be built a new urban spatial layout relying on subway construction.Some suggestions of related issues also be put forward.
