[Objective]To study the response of plant community characteristics and species diversity of degraded temperate desert grasslands to reseeding,which provides a scientific basis for the restoration and management of degraded grasslands.[Methods]This study takes the degraded Seriphidium borotalense desert as a research object,and selects locally suitable plants(Seriphidium borotalense,Bassia prostrata,and Artemisia sieversiana)for reseeding,and monitors the quantitative characteristics of grassland vegetation in the field.[Results]Compared with the control site(CK),reseeding significantly increased the important value of Seriphidium borotalense,and significantly increased the biomass by 65.96%(P<0.05).Reseeding was beneficial for maintaining plant diversity,and significantly increased the patrick richness index by 52.83%(P<0.05).[Conclusion]Reseeding measures are beneficial for the restoring of degraded desert grassland vegetation communities,and maintaining of plant diversity.
