| 摘 要： | 对内蒙古草原主要植被类型荒漠草原、典型草原、草甸草原土壤动物区系分布、群落特征进行了研究．结果表明：该地区不同草原土壤动物大类群水平优势类群基本一致．土壤动物密度及生物量以荒漠草原较低，而典型草原较高，草甸草原则以低密度和高生物量显示了其土壤动物分布的特殊性．内蒙古草原地带不同植被类型土壤动物群落在类群组成上显示较强的同源性和在较低分类阶元上的分异性．

| Abstract: | The community structures of soil animals in different steppetypes were studied.The dominant groups of soil animal were similar in different steppetypes.The densities and biomasses of soil animal in desert were lower than that in typical steppe.In meadow,lower density and higher biomass of macrofauna fully showed its special feature of the conmmunity structure.The main difference of soil animal community structures in different steppetypes were that they had different species of soil animals. |
