Abstract: Diversity of Coleopteran community in the desert steppe at different grazing rates were studied using baited pitfall traps. A total of 5 256 coleopteran individuals were captured and fell into 14 families,among which Carabidae,Silphidae,Scarabaeidae were dominant. The number of beetles was decreased by grazing intensity, Community diversity was the largest in heavily grazed grassland, and the smallest in lightly grazed grassland. Community dominance of contrast, Moderately grazed meadow, heavily grazed meadow, were significantly higher than lightly grazed meadow（P 0.01）.Different beetle species appeared at different time, The peaks of Individual numbers at different stocking rates were different. The dominance of different species in the same habitat was different by time. Plant cover, biomass, litter dry weight, soil organic matter,soil p H, soil moisture were the main factors which affect the beetle community.
