Abstract

This study focused on the Tetraena mongolica plant community,examining the effects of different grazing intensities light grazing(LG),moderate grazing(MG),heavy grazing(HG)and no grazing(NG)as the control,onplant species composition,species diversity,biomass,and population regeneration.1)As grazing intensity increased,the importance value of dominant species Tetraena mongolica in the community showed an upward trend.HG reduced the importance values of Cleistogenes songorica and Eragrostis pilosa in the herbaceous community,while increasing the importance values of Allium mongolicum and Peganum harmala.2)Compared to NG,grazing reduced the height,coverage,density and aboveground biomass of herbaceous communities.No significant changes in the height,density and aboveground biomass of shrub communities under grazing treatment,although the coverage showed a trend of initially increasing and then decreasing.3)Compared to the NG area,grazing significantly increased the Shannon-Wiener,Margalef and Simpson indices of the herbaceous community,while significantly reduced the Shannon-Wiener index of the shrub community.4)Aboveground biomass was positively correlated with the Shannon-Wiener and the Margalef indices in all areas.It was positively correlated with the Pielou index in NG,LG,and MG areas,but shows no correlation in the HG area.It was negatively correlated with the Simpson index.5)The density of seedlings of the Tetraena mongolica population was higher in the MG and HG areas compared to the NG area.In summary,the structure and function of Tetraena mongolica plant communities are affected by grazing behavior,with the herbaceous community showing a more significant response than the shrub community.Therefore,MG is beneficial for controlling the herbaceous community and protecting Tetraena mongolica populations.

Key words： Tetraena mongolica; grazing intensity; community characteristics; species diversity; biomass
