To a certain extent, terrain factors have effects on the formation and change of land use spatial pattern, especially in plateau region. We selected Panxian County in Guizhou Province as the study area, and used the geological information mapping theory, terrain distribution advantage index, terrain index gradient and land utilization comprehensive index to systematically and quantitatively analyze the spatial distribution and intrinsic evolution characteristics of land use of research area in the topographic gradient in the period from 2000 to 2010. The results showed that during the study period, in Panxian, cultivated land reduced greatly, forestland, grassland, construction land and water bodies increased a lot, change of unused land was not obvious; spatial distribution of different land use types and their changes under the influence of terrain factor had vertical distribution characteristics. Terrain advantage of low level terrain area of cultivated land enhanced, terrain advantage of water body significantly shrinked, in middle level terrain area, terrain advantage of forestland and grassland remained stable. In high level terrain area, distribution range of terrain advantage of forestland and grassland became wide, construction land and water body shrinked. The changes of land use map are given priority to stable type and precancerous change type, different types are the changes of cultivated land to forestland, grassland and construction land conversion as the main characteristic in different terrain areas. The comprehensive land use degree index increased first and then remained stable with the increase of terrain area. Adjustment of land use structure in the plateau region should take full consideration of terrain structure and the vertical gradient of land use structure, optimize the layout of different land use types in arrangement and coordination of adjust measures to local conditions, to realize appropriate arrange and sustainable utilization of land resource on the spatial structure.
