In order to investigate the effect of grazing on the inherent Arthropod-Plant relationship, various adaptive intensity grazing management experiments were conducted on typical steppe in Inner Mongolia. At the community level, arthropod richness was higher in light and heavy grazing than in moderate grazing, but there was no significant difference between grazing and no grazing. Both arthropod communities and Coleoptera prefer to survive in relatively dry soil environments. The lower the plant biomass, cover age, and height, the higher the Coleoptera abundance, likely due to grazing shaping a more open feeding space for visual predators. However, dry soil and more open feeding space are accompanied by more intense grazing interference, and the stronger the direct interference, the lower the biomass of arthropods, especially Coleoptera. The direct disturbance of grazing to arthropods (involuntary feeding and trampling) may often be underestimated, these direct disturbances may mask the indirect disturbance of grazing to arthropods through plants, and grazing may cause arthropods to choose a more stable environment rather than a better one. This means that it is necessary to incorporate surface arthropod-related monitoring data into the sustainable development and utilization management system of grasslands.
