The monitoring study of 104 sampling sites, 31 species belong to 13 families were conducted in Mongolian typical desert-steppe ecosystem, main desert-steppe rangeland communities dominated by Allium-polyrhizum Turcz. Ex Regel, Stipa tianschanica var. gobica (Roshev.) P.C. Kuo&Y.H. Sun, Agropyron cristatum (L) Gaertn., Cleistogenes songorica (Roshev.) Ohwi, under sustained grazing influence. The different grazing approaches effect steppe types ecosystem plant production and soil formation. Species abundance, species richness vegetation cover in order to identify changes in rangelands and sustainable grazing management system. Three years (July-August 2012-2014) biomass data were analyzed for the effect of the management system, livestock grazing and non grazing, aboveground net primary production and litter accumulation. Canopy cover of production units was increased by the non grazing intensity (P<0.005) in 2013, annual precipitation (20mm) was increased in June-July. Correspondingly, soil erison decreased 2013 and 2014 (P<0.005) 12%. In this study, basic characteristics of plant communities along the livestock grazing and non-grazing (fence) gradient were also analyzed. A relationship between ANPP and species richness growth function (R 2 =0.79, P <0.02); whereas on the grazing (non-fence) point the relationship takes the form of exponential decay (R 2 =0.12, P <0.01).

Our research area northern Khangai mountains refer to humid type and compose steppe vegetation of lower range.
