摘　　要：本文应用系统聚类法,对内蒙古荒漠草原东段啮齿动物群落进行分类研究。应用Whit-taker相似性指数I=1-0.5∑|ai-bi| 作为聚类指标,初步将17个样地内所获5科18种啮齿动物划分为8个群落。经与相关系数的聚类结果比较,认为前者更能反映该段啮齿动物的组成特点和群落结构特征。The systematic studies of rodents community in the eastern part of desert-steppe were carried out by using hierachial clustering method. By using Whittaker's index of similarity I= 1-0.5∑ |ai-bi| as clustering index, 18 species of 5 families were classfied into 8 communities: 1. Meriones unguiculatus + Citellus dauricus community! 2. Meriones unguiculatus community) 3. M.unguiculatus + Allactaga sibirica community) 4. M.unguiculatus + Lagurus luteus + Ochotona daurica + A.sibirica community) 5. M.unguiculatus + C.dauricus + Dipus sagitta community) 6. M.unguiculatus+ C.dauricus + C.erythrogenys community) 7. C.dauricus + M. unguiculatus community; 8. O.daurica + M.unguiculatus community; Compared with the cluster result of correlative coetficient, this result was more ab-le to represent the component characteristics and community structure of the rodents in this part.
