Abstract： To investigate the impacts of grazing on ground-dwelling arthropod communities in typical grasslands，147 pitfalltraps were deployed acrossdiffrent grazing management sites in Abaga Banner，Xilin Gol League，Inner Mongolia. A total of 12 059 arthropod individuals were captured，which belonged to 2 classes， 12 orders，and 83 families.The dominant groups were Formicidae，Carabidae，and Acridoidea.The number ofarthropod species in the pasture of no grazing （O sheep unit hm-2⋅a-1） ，light grazing （O.34 sheep unit·hm-2⋅a-1） ， moderate grazing（O.69 sheep unit·hm-2⋅a-1） and heavy grazing（1.53 sheep unit·hm-2⋅a-1， ）were 50，66，60 and 6l families，respectively. The results indicated that grazing helped increase the number of arthropod species，abundance，and richness，but decrease evenness.Predatory arthropods exhibited higher diversity in lightly grazed grasslands and greater activitydensity in heavily grazed grassands，while herbivorous arthropods had the lowest diversity and activity density in no grazing grasslands. Correlation analysis revealed that arthropods in no grazing grasslands were more strongly associated with soil physicochemical properties. In conclusion，arthropods respond diferently to varying grazing intensities and can serve as bioindicators for grassland grazing management.
