Abstract:: Fencing and grazing are important factors in grassland ecosystem. Based on the investigation data, the influence of fencing and grazing on species composition, biomass, cover, density, shoot numbers and species diversity of aboveground vegetation had been examined in typical steppe on the Loess Plateau. Results showed that fencing and grazing had significant influence on vegetation structure. Compared with grazing, fencing significantly increased total cover and aboveground biomass, but significantly reduced the density of vegetation and shoot numbers. Fencing significantly increased grass biomass of aboveground vegetation, but significantly decreased forb biomass of aboveground vegetation. Fencing significantly reduced grass shoot numbers, but had no significant effects on forb shoot numbers. Fencing and grazing significantly affected species richness, Margalef index and Shannon-Wiener diversity index, but had no significant effect on Simpson index and Pielou index. Compared with grazing, fencing significantly reduced the species richness, Margalef index and Shannon-Wiener diversity index of aboveground vegetation.
