%X The landscape condition of the sandy grassland in southeast of Ordos Plateau was analyzed based on the data from field investigation along two intercepting 5 km transects. Summary on frequency of the patches showed that small scale patches were prominent in this area, with 95% of total patches smaller than 50m and average dimension of patches 15m, while there were also a couple of large scale mobile sandy patches. Environmental heterogeneity dependent on spatial scales was revealed by semivarogram in the sampling area. The large fractal dimensions of percent coverage of bare ground, close to 2, indicated dominant small scale spatial variance. This result implies a relative stabilized landscape and also a desertified area.
