Abstract: Based on the land use data, land use maps and DEM data in 2014 and GIS technology, the topographic variation of land use in Beibei District was revealed via distribution index, Lorenz curves and Gini coefficient from the perspective of slope and elevation. It was shown that the distribution characteristics of regional land use type were closely linked to elevation and slope. Woodland and unused land advantages were mainly distributed in the area of high terrain level. The advantages of the construction land, arable land and garden land increased gradually with the decrease of terrain level. Slope showed significant influence on spatial distribution of all land use types. The area in the elevation of 300-400 m and slope of 6-15°was the mean area for urban expansion and arable land protection. The distribution of arable land and garden land on terrain was similar, but the construction land, woodland and other agricultural land exhibited regional differences. The distribution of land use type showed obvious hierarchy. Based on terrain advantage level, it increased as water layer, construction land layer, arable land layer, garden layer, and woodland layer. Combined with land use pattern, 5 functional regions in the study area were designed, namely, the core of water area, urban development area, modern agriculture development area, ecological agriculture development area and ecological barrier area, and corresponding land development suggestions were put forward.
