Abstract: The systematic studies of rodents community in the eastern part of desert-steppe were carried out by using hierachal clustering method.By using Whittaker's index of similarity I=1-0.5Σ∣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.daurieus+C.erythrogenys commmaity; 7.C.aaurlcus+M .unguiculatus community; 8.0.daurica+M .ungulculatus community; Compared with the cluster result of correlative coefficient,this result was more able to represent the component characteristics and community structure of the rodents in this part.

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Whittaker相似性指数I=1-0.5Σ∣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。
