Abstract:: A field survey was conducted to investigate the vegetation community characteristics and species diversity of enclosure with the quadrat method in Hongsongwa Natural Reserve for 5 years from 2012 to 2015. The results showed that the dominant species of the plant community did not change significantly during the five years of enclosure, but with the increaseof enclosure age, the important values of the dominant species and other species in the fence changed. In particular, Sanguisorba officinalis， Artemisia tanacetifolia increased significantly, and Carex rigescens decreased most. The height, coverage and aboveground biomass of plant communities increased obviously (p<0.05). From the analysis of different economic groups, the proportion of excellent forages and medicinal plants increased, while the proportion of miscellaneous grass decreased. The plant community richness index, species diversity index and evenness index increased significantly (p<0.05) after five years of enclosure.
