Recognizing the function of a natural ecosystem and awareness aware of its potential require to knowledge of the characteristics and the soil and plant represents.Evaluation of important characteristic of soil and vegetation identify potential ability of rangeland and it is possible to determine the rangeland condition. The purpose of this study is Comparison and determine the function of soil surface indicators the ecological patches in both the eastern and western slopes, in Lishter rangelands of Kohgiluye and Buyerahmad province. In order to, in eastern and western slopes, 3 transects of 50 meter in the along slope, patches and inter patches in the area (5 repetitions) were established. Patches in western slopes including (Cousinia sp., Centaurea intricanta Boiss and Astragalus sieberi), inter patches including (bare soil, gravel) and also patches in eastern slopes including (Stachys byzantina C. Koch and Astragalus fasciculifolius Boiss) and inter patches (bare and litter). Landscape Function Analysis model were used to measure stability, infiltration and nutrient cycles using the 11 soil parameters. To compare, the western and eastern slopes the t-test was used. The results showed significance difference among stability, infiltration and nutrient cycling in both eastern and western slopes (p<0/05). Three indices in Cousinia sp. patches in eastern slope and Astragalus fasciculifolius patches in western slope compared to other patches in this study there were more.
