Abstract:: The enclosed pasture has an important role in the important measures of controlling grassland degradation and grassland vegetation ecosystem diversity protection. In this study, different grass types (typical grassland, wetland meadows, grassland desertification) were taken as the objects in the natural protection area of Hui river. The vegetation biomass, height, coverage, plant density and plant species diversity of inside and outside of enclosure in different typical region had surveyed and researched. The results show that: the typical grassland, wetland meadows, grassland desertification biomass fence rose up to 20.4%, 88.8%, -29.9%, relatively highly increased by 5.2%, 91.9%, -36.3%, respectively, and the vegetation coverage increased by 64.5%, 43.4%, -17.5%, respectively, plant density increased by -14.0%, 135.5%, 72.5%; The gramineous, leguminosae, compositae plants in outside of enclosure had increased due to graing. The community similarity grass in different types of inside and outside of enclosure is not big, the community species composition changed a lot. Through the analysis of enclosure of biological diversity variation rules and the influencing factors, theoretical support way was put forward to protect the natural ecological system.
