Abstract：Based on GIS spatial and temporal analysis model, geo-information atlas theory were used in this paper. Land use data were extracted from spatial data of three periods（1987, 1997, 2007）in Tongbai-Dabie mountainous area. Land use change atlas and arising/declining atlas from 1987 to 2007 were established. Land use changes characteristic were analyzed, and land use changes were predicted. Results indicate that land use changes significantly during the past 20 years. The area of farmland decreased, and forest land and construction land increased. Grassland and unused land increased firstly, then decreased, vice verse water land decreased firstly, then increased. From the spatial series, mutual transformation between farmland and forest land was obvious in the whole research area. Farmland and forest land transfered to construction land in the nearby of town. Waters transfered to farmland and forest land in the nearby of waters. In arising/declining atlas, the largest expanding atlas was forest land, with an increase of 5904.06km2, accounting for 61.31% in expanding atlas, mainly from farmland and water land. And the largest shrinking atlas was farmland, with a decrese of 6394.71km2, accounting for 66.41% in shrinking atlas, mainly transforming into forest land and construction land. In the future, farmland and forest land will continue to be chief land use type.
