چکیده
In this paper,it gave a detailed introduction about the classification process of land use in Guangzhou supported by RS and GIS software using the data of Landsat TM of 1997 and 2003. After being geometric corrected subset and enhanced, the images were classified into 9 classes as farmland, orchard, forest, disk-pond, urban and rural land, developing area, river, lake and unused land by using maximum likelihood classifier. The total classification accuracy was given at last. And then mathematic method was used to analyze the land use change by the conversion matrix, including the quantity changes, the speed changes, the space changes and the region difference. 1 *Corresponding author: E-mail:[email protected] Fax:+86-020-87685141
