Abstract: The dynamic change of land use in Yanji City was computed and analyzed by using the geometric correction, supervised classification and change detection statistical methods based on 3 Landsat TM/ETM+ images taken in 1991, 2001 and 2006. The results showed that, the area of residential land has increased significantly. On the contrary the area of agricultural land and grassland has decreased. The grain problem and the environment problems due to the changes of the land use would seriously affect the daily life and the ecological environment of Yanji City. The result of the study could provide a theoretical basis for the effective management and sustainable development of Yanji City.
