Abstract

Management practices impact rangeland structure and function. Rangeland assessment help interpretation and judgment about theses practices. The most important factors that cause rangeland to be disturbed are GRAZING INTENSITY and LAND CULTIVATION. So for investigation of these practices effect in arid rangeland, one shrub community was selected in Rudshor Save region. In this community, five cases included: three GRAZING INTENSITY (heavy, moderate and weak), recently cultivated area and relict area that cultivated last years were investigated. Landscape function analysis (LFA) method was used to evaluate practices effects on soil surface characteristics and rangeland FUNCTIONAL ATTRIBUTES investigated. In this method for determination of three FUNCTIONAL ATTRIBUTES included: stability, infiltration and nutrient cycling 11 SOIL SURFACE INDICATORs included: soil surface cover (soil protection from erosion), perennial canopy/basal cover, litter (cover, origin, degree of decomposition), cryptogam cover, crust brokenness, type and severity of erosion, deposited material, soil surface roughness, soil surface resistance to distribution, slake test (soil stability test) and texture were used. Results showed that by increasing GRAZING INTENSITY, perennial vegetation cover and soil surface resistance reduced.Also breaking soil crust created bare soil. Finally rill, terraces and pedestal erosions increased.Rangeland cultivation reduced stability and increased its infiltration. In relict area because of reestablishing perennial vegetation, soil indicator and functional attribute were improved. We found that LFA method able to show changes of management effect at last consumption a few money and time shows the capability of this method.
