Abstract: Based on ArcGIS9.3 and accessibility analysis technology, this article analyses the evolution of accessibility pattern of land use for different function quantitatively in Huai′an City and comes to the conclusions: The first, with the expansion of urban space, the range of accessibility time is also expand correspondingly, the level of accessibility changed a little in the core of city but changed significantly in the edge of city, and the increase of the level of accessibility in the core city will lead the city to development concentration further, and the increase of the level of accessibility in periphery of the city will lead the urban development elements to spread. The second, there are the close relationship between spatial distribution of urban land use and the level of accessibility. The land use for main function concentrated in lower-cost accessibility time; the evolution of accessibility spatial pattern of main function land shows different characteristics; industrial land migrate gradually from lower-cost accessibility time in urban core area to higher-cost accessibility time in urban periphery; the residential land is distributed in the different accessibility time uniformly; the small public facilities land distribute in lower-cost accessibility time in urban core area mainly, but the public facilities land migrate gradually to higher-cost accessibility time in urban periphery. The third, on the basis of the results mentioned above, we summarize five factors which impact on the evolution of accessibility pattern of land use for different function, such as natural conditions, economic development, transportation guide, population growth and government regulation. The increase of accessibility level can guide the urban development elements to concentrate development; city government should take the effective measures to improve the accessibility level by planning and building the road network in the connection zone of the two city subdivision, and to guide the urban transition zone to development rapidly. Only in this way can the city subdivision turn into one city and effective use the city public resources.
