摘要：

Taking the sub-basin region of water resource in the Liao River Basin as research area, land use data of the Liao River Basin in 1980 and 2000 were used to set up conversion matrix of each sub-basin region on GIS platform, and the temporal-spatial change characteristics of land use in the Liao River Basin was analyzed quantitatively. The results shows that farmland, woodland and grassland play a dominant role in the study area; During the period of 1980-2000, the main forms of land use conversion in the whole basin were the conversion from grassland and woodland to farmland, and in the Mainstream Liao River region and Huntai river region the conversion trend from farmland to construction land was obvious; The land use change in the West Liao River region and mainstream Liao River region made a significant contribution to the land use change of the Liao River Basin.
