摘要：By using two-period(1980,2000)remote sensing images and with the support of GIS and RS, spatial pattern of land use change of Jilin province in recent 20 years is interpreted and extracted, and elucidated the human driving forces for the changes of cultivated 1and. Results showed that in the period 1 980 to 2000, the main trends of Jilin province's 1and use change were the transforming from grassland, woodland, and unused 1and to cultivated 1and.Among which, the transformed area from grassland to cultivated 1and was 35.01 percent of the tota1 transformed area. And the dynamic degree of grassland was the biggest. In the process of land use change, the intensity of human 1andscape has been enhanced. The spatial difference of 1and use change was obvious, and the change in western of Jilin province was very big. The transformed cultivated land from grassland and unused 1and mainly distributed in the northwest. The transformed area from woodland 1ocated in the edge region of woodland: the transformed urban from cultivated land distributed in the middle district where gathered many cities. In addition, part of grassland in the west as degraded to unused land. Population increase, economic development and macroscopic policy were the major driving forces for 1and use change of the studied area
