The changes of plant community characteristics and vegetation ecological quality in a degraded arte-misia frigida grassland monitoring sites under different management measures of enclosure and grazing from 2019 to 2023 were studied.The results showed,compared with grazing,enclosure was beneficial to the ecological restoration and development of degraded grassland,and could improve the grassland vegetation productivity and species diversity,the height,coverage and average density of vegetation community were also increased.Judging from the extent of the increase,enclosure had the greatest effect on community height,followed by average density,and had relatively less ef-fect on community coverage,productivity and species diversity.Enclosure has a significant positive effect on vegeta-tion quality restoration,the vegetation quality of enclosed monitoring sites was one grade better than that of grazing.
