摘　　要：本文根据１９９３．８～１９９５．５的调查资料并采用了聚类分析对达坂城地区荒漠及农业区鼠类群落进行了分析研究，结果表明，该地区的鼠类可划分为３种群落，小林姬鼠＋褐家鼠＋小家鼠群落（Ａ）；小林姬鼠＋灰仓鼠群落（Ｂ）；红尾沙鼠＋五趾跳鼠群落（Ｃ）；群落的多样性指数以群落Ａ最高（１．４７９７），次为群落Ｂ（１．１５４６）；群落Ｃ的多样性最低（１．０４３４）。种的多样性和生态环境的差异有关，随着人类经济活动的增加，经营时间的不同，鼠类群落受到的影响程度也不一样。在荒漠向人工环境转化过程中生存于其中的鼠类也呈现有规律的演替现象。In this paper we have used of the cluster analysis method study on rodent communities structure in Dabancheng area from August ,1993 to May,1995 The result indicates that the rodent communities in this area could be divided into three types;1.A.sylva-ticus +R.norvegicus+M.musculus commknities (A); 2.A.sylvatius+C.migratorious community (B); 3.M.crythrourus+A.sibirica community (C).Species diversity indexes of different communities are different. The highest indexes have been found in community A(1.4797) the next is comminity B(1.1546),and the lowest in community C(1.0434).The indexes are related to the variation of the ecological environment ,in pace with increasing economic activities of human being and time difference of human activities the influence of different rodent communities is different.The desent change of artificial landscape and regular success have been come into being among rodent species in this area.
