Driving Force Analysis of Land Use Chang of Beijing Urban Areas in the Past 20 Years
Based on LandsatTM remote sensing data of 1989,2000 and 2008 of Beijing six urban areas and with the technology of GIS,the paper displays the range,speed and direction of the land use change in the past 20 years and conducts the driving force analysis.The result shows that the urban area in Beijing develops rapidly which decreases the farming land area and water areas,while the area of the forest and grassland at the edge of the urban area changes slightly.
