The Study on the Urban Spatial Structure Change By High Resolution Remote Sensing Imagines—the Case of Shijiazhuang City

Urban spatial structure change is one of the most important parts of urban features, it comes from the process of the urbanization and has both inner filling and outward expansion. Under the support of high resolution remote sensing images and geographic information system (GIS), this article analyzes the urban spatial structure changes in the built-up area of Shijiazhuang city from 1994 to 2003. These analyses focus on the aspect of the urban land types and its area, the value of urban land assets and the density of land assets and its change rate, the various types of building area and the building floor area ratio (FAR), the urban population size(PS) and population density(PD) and its change rates. The study discloses the laws of urban spatial structure evolution in order to compile the master urban planning and administrate urban construction.
