Diverse topography and complex landforms occurred China, and the geographical distribution of animal exhibits significant differences across geographical regions. Based on literature research, the latest species diversity data, 692 species (belonging to 13 Orders, 56 Families and 246 Genera) of mammals in China were obtained. By using multivariate similarity clustering analysis (MSCA) method, zoogeographical distribution of mammals in China was analyzed according to 639 species (13 Orders, 49 Families, 215 Genera). The results showed that: 1) current zoogeographical distribution of mammals in China was categorized into 176 investigated geographical units (IGUs), and then merged into 63 basic geographic units (BGUs); 2) when taking the similarity coefficients values of 0.31, 0.25, and 0.15, the basic geographical units of mammals in China could be clustered into 10, 7 and 2 groups of BGUs, respectively. Consequently, a 3-level zoogeographical division, 2 Realms, 7 Regions, and 10 Sub-regions, of mammalian distribution of China was established. The result from this study suggested that the boundary between the Palaearctic and Oriental Realms within China in the World zoogeographical distribution Division should be seated in line with western Namjagbarwa Peak - Maqinggangri - northern Qinling Mountains - southern margin of Loess Plateau - Dabie Mountains - southern Huaihe River
area- middle and lower reaches of Yangtze River.

中国的地形复杂、地貌多样,动物的地理分布亦表现出明显的区域间差异。本研究通过新近文献调研,获知中国现生哺乳动物计692种(隶于13目56科246属);进而建立物种及其地理分布数据库。采用多元相似性聚类分析(multivariate similarity clustering analysis, MSCA)方法,探讨了中国哺乳动物的地理分布特征。结果表明:(1)中国的现生哺乳动物可划分为176个调查地理单元(investigated geographical unit, IGU),进而归并为63个基础地理单元(basic geographical unit, BGU);(2)当相似性系数取0.31、0.25和0.15时,上述63个BGU可分别归并为10个、7个和2个基础地理单元群;据此可对中国的哺乳动物地理分布作出2界7区10亚区的3级区划。本文建议,世界动物地理区划中古北界与东洋界在中国境内的分界线走向为:南迦巴瓦峰西部—玛卿岗日—秦岭北部—黄土高原南缘—大别山—淮河南—长江中下游一线。
