The Evolvement Mechanism of Land Use and Urban Space Structure Along Rail Transit

Previous attempts to obtain the qualitative interpretation that rail transit affects the land use and urban space structure are lack of effective quantitative evaluation model. In this paper the evolvement mechanism of land use and urban space structure along rail transit can be proposed to objectively reflect the relationship and the complexity between rail transit and land use structure. Firstly, the land development intensity in suburb when rail transit opened in Beijing can be obtained. Then, the information entropy model can be used to evaluate the land use structure along the rail transit in three development stages that is 2003, 2007 and 2010 respectively. Finally, the land use structure along different type of rail transit station can be proposed. It shows that the passing by rail transit plays a significant role in space structure of suburb. Meanwhile, the residential, financial and official land development may be attracted along rail transit and industrial land repelled according to their information entropies. Especially the financial and official land development is closer from rail transit station, its intensity is higher and the scope of attraction is expanding.
