Analysis of Urban Land Use Growth in Shijiazhuang City

Urban land use presents the social economic activities through the coverage of physical component filled in three-dimensional space. More analyses on urban land use often focus on the aspect of urban expansion or urban inner intensive utilization,and few pays any attention to a comprehensive analysis including area extension and intensity growth. To some extent,this im-pacts the objective understanding of urban land use. Under the support of high -resolution remote sensing images,adopting the studying index such as single land use change rate,comprehensive dynamic degree of land use,land use relative change rate,intensity growth index and so on,integrating land use alteration and land use intensi-ty change,this article analyzes the urban land use growth in the built-up area of Shijiazhuang city from 1994 to 2002. This paper found: The comprehensive analysis of the integrated land use alter-ation and intensity change is helpful to comprehend urban land use change correctly,and intensity growth index can integrate two aspects of urban land use change effectively. Arable land loss is continuing during the urbanization process in Shijiazhuang,and cropland is still the main way to meet urban development need,although land intensive use has been another important source for land use growth. As a whole,urban spatial organization is oriented to land intensive use in a way of circle pervasion,and urban land use trends to be more reasonable. Urban land use change dis-plays prominent difference in spatial dimension,and land use in central area develops more verti-cally,while other areas adopt the filling,outward expansion and urban renewal to achieve the growth of urban land use target. Land use change also represents location differences in land use type in a way that land use change in central area mainly centralizes on the type with advanced urban attribute such as commercial land,and the premier in other areas is the inferior quality type such as industrial land and so on.
