摘　　要：利用样方统计法,对内蒙古高原东南缘森林草原过渡地带森林、森林草甸、草甸草原和草原4种不同土地利用类型大型土壤动物群落结构进行了研究。共采集大型土壤动物2 394只,隶属于3门8纲22目(类)。由森林向草原过渡过程中,大型土壤动物群落组成变化较大,土壤动物个体数量和类群数呈递减趋势。统计分析表明,大型土壤动物类群数和密度-类群指数(DG)在不同土地利用类型之间存在显著差异(P<0.05);森林带大型土壤动物个体数量显著大于森林草甸、草原和草甸草原(P<0.05),多样性指数(H′)显著大于草原带,均匀度指数(J)在4个土地利用类型之间无显著差异(P>0.05)。森林具有最高的大型土壤动物个体数量、类群数、H′值和DG值,其次是森林草甸,草原带最低。Community structure of large size soil macrofauna were studied by quadrats statistical methods under four different land use types, including forest, forest-meadow, meadow-steppe and steppe in forest-steppe ecotone of Southeastern Inner Mongolia Plateau. There were 2 394 soil macrofauna individuals be-longing to 22 orders, 8 classes and 3 phylums, and there were large changes in community composition and an obvious decreasing trend in the number of individuals. Besides, there were groups of large size soil mac- rofauna in the transition process from forest zone to steppe zone. It showed a significant differences（P~ 0.05）in the number of groups and density-group index（DG）of large size soil macrofaun between different land use types. The number of macrofauna individuals in forest zone were significantly higher than that in forest meadow, meadow-steppe and steppe zone, and the diversity index （H＇） in forest zone was signifi-cantly greater than that in steppe zone. In contrast, there were no significant differences in evenness index （J） between four land use types. In short, the forest zone had the highest number of individuals, groups, H and DG values, followed by the forest-meadow zone, meadow-steppe zone and steppe zone.
