N2 - Introduction Intensive land use and especially overgrazing in semi?arid grasslands results in degradation of steppe vegetation associated with changes in the amount ,composition ,and turnover of soil organic matter (SOM) . The concurrent degradation of soil structure and destruction of aggregation leads to enhanced soil erosion .The effectof intensive grazing on the amount and composition of SOM was assessed by comparison of grazed and ungrazed plots in Leymus chinensis and Stipa grandis dominated steppe types in Inner Mongolia ,China ID - orgprints39178 TI - Intensive grazing leads to degradation and spatial homogenization of topsoils in two major steppetypes in Inner Mongolia , P .R .
