【Objective】To reveal the community characteristics and vegetation diversity of Seriphidium transiliense desert response to short-term enclosure,and provide the theoretical basis for the restoration and reconstruction of degraded sagebrush desert. 【Method】In this study,in order to discuss the effects of short-term enclosure on the characteristics and diversity of desert communities,the coverage,height,density and biomass of the community were studied by field monitoring method,and the diversity indexes of community vegetation were calculated.【Result】( 1) The community height,coverage and biomass increased significantly by 89. 7%,153. 9% and 130. 8%( P 0. 05),while the community density decreased significantly by19. 8%( P 0. 05).( 2) Compared with the enclosed area,the Simpson index and the Pielou index of the grazing area were significantly higher than those in the enclosure area( P 0. 05),the Shannon-Wiener index was slightly higher than that of the enclosure area,while the Margalef index was lower,but the difference was not significant( P 0. 05).【Conclusion】Enclosure has become the most effective measure to restore and reconstruct degraded grassland,and the biomass of grassland community can be increased by enclosure,but the species diversity index is low,and the grazing reduces richness index.
