In order to explore the effects of moss crust on the growth of common grass and soil properties in alpine meadow， Elymus breviaristatus was used as a material. And the effects of moss inoculation on the growth and soil properties of E. breviaristatus were studied under indoor pot conditions with different moss inoculation rates （10 g·pot^-1， 15 g·pot^-1， 20 g·pot^-1 and no moss inoculation as a control）. The results showed that the inoculation of moss could promote the germination and growth of the plant. Under the condition of 10 g·pot^-1 inoculation， the germination rate， plant height， aboveground and underground biomass， and relative water content of plant were increased by 32.0%， 25.1%， 93.1%， 135.4% and 37.4%， respectively. The contents of soluble organic carbon， available nitrogen and microbial biomass carbon and nitrogen in soil increased to different degrees after moss inoculation. The activities of urease， sucrase， α-1， 4-glucosidase， β-1， 4-glucosidase， cellobiohydrolase and β-1， 4-xylosidase in soil increased by 69.2%， 372.5%， 197.2%， 110.1%， 44.2% and 105.6%， respectively. The effect was particularly obvious under the treatment of 15 g·pot^-1 inoculation. The correlation analysis showed that there was a significant correlation between the growth index and soil properties， and moss inoculation affected the growth of the plant by changing soil properties. Therefore， in the restoration of degraded alpine meadow， it can be considered to inoculate an appropriate amount of moss to improve soil fertility and to promote vegetation recovery， which provides a theoretical basis for the near-natural restoration measures of alpine meadow using moss.
