Abstract: The vegetation community characteristics in desert steppe region in different grazing patterns were investigated. The results indicated that the height and density of Stipa tianschanica var. klemenzii were highest in all-day grazing region and its coverage was the highest in contrast region. The height of Cleistogenes mutica was the highest in contrast region, and its coverage and density were highest in the night-grazing region. The height and density of Leymus secalinus were higher in the day-grazing region and its coverage was the highest in contrast region. The overground biomass in night-grazing region was lower in July, August and September.
