In this paper,the classification process of land use in Guangzhou was described by using Landsat TM data between 1997 and 2003.After being geometrically corrected,subseted 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 also reported in this paper.A mathematic method was used to analyze the change of land use by the conversion matrix of land use from 1997 to 2003,including the change-amount,the change-rate,the change-transition and the regional difference.Two important results were obtained by this research: (1) There was no significant change on land use of Guangzhou during 1997~2003;(2) a distinct difference was found on spatial distributing of land use of Guangzhou from 1997 to 2003.
