石家庄市城市边缘区扩展遥感分析研究

Remote Sensing Research on Urban Fringe Expansion in Shijiazhuang City

利用两期(2002年和2007年)的IKONOS、QuickBird、CBERS-02B为数据源,通过分析不同时期土地利用类型的变化过程,重点是城市边缘区的变化,进行城市边缘区扩展研究。研究内容主要为城市边缘区扩展中不同土地利用类型的动态变化,包括空间分布、类型、数量。研究表明,城市扩展的变化主要发生在城市边缘区,2002至2007年间,城市边缘区各种土地利用类型的数量有明显变化。主要是农业用地的减少,从61.94%减少到了53.07%,减少比例接近9%,转换为水域和其他用地、工业用地、居住用地。研究成果为石家庄城市规划建设提供了基础数据。

The remote sensing data source(2002 and 2007)used in this research is IKONOS、QuickBird and CBERS-02B data.On the base of dynamic investigation on land use,analyzed the changing of different land use type in different period,especially on urban fringe changing.We focus on the dynamic change of different type land use in urban fringe expansion,including distribution,type and quantity.Result shows that the main change of city expansion is occurred in urban fringe,from2002 to 2007,while changing is dominant by agricultural land whose decrease in area was almost 9%.It converted to water,industrial land,residential land or other land(mainly rural construction use land).The result can be taken as the basic data for urban planning and construction in Shijiazhuang city.
