Research on Spatial Structure of Urban Land Use Intensity based on GIS

Taking urban construction land of Acheng District in Harbin as the research object, by means of high-precision satellite image and large-scale field survey, adopting GIS and statistics, taking four spheres of urban land use structure as space limits and spatial distribution of capital density as an entry point, this paper quantitatively studies the spatial distribution law of land use intensity. The results show the spatial structure of land use intensity is consistent with the law of differential rent. Except that land use intensity of the outlying area in industrial land is higher than that of the transitional area, land use intensity of commercial land and residential land declines as the distance from urban center increases; Land use intensity of the district offices and the development history of every district are positively related; Land nature, location factors and administrative developing history are important driving forces of Acheng urban land spatial pattern.
