The results of species richness patterns showed that there was higher species richness of mammals in the mountainous regions than plain regions,that is species richness in the mountainous region of southern Anhui was higher than in Dabieshan,western Anhui,and species richness in the hilly region between Yangtze River and Huaihe River is higher than the plain region of northern Huaihe River. Cluster analysis of distribution units by species showed that the 425 units could be designated into 9,5,3 and 2 groups,where Jaccard similarity was 0.647,0.570,0.461 and 0.399. The result indicated the distribution of mammal species were relative to human activities and landform. Cluster analysis of distribution units by range types showed that the 425 units could be designated into 9,5,3 and 2 groups,when Chisquare was 1.561,1.759,2.521 and 3.509. In order to study the boundary between the Palearctic and Indomalayan (or Oriental) Regions in Anhui,we sorted all mammals species into 4 range types according to their ranges and origin. These range types were identified as: (1) Palearctic (species with ranges or major ranges in Palearctic),(2) Indomalayan (species with ranges or major ranges in Indomalayan),(3) Southeast-Asian (species with ranges extending to both sides of the boundary between the Palearctic and Indomalayan regions and that only in Southeast China,Korea,and Japan),and (4)Widely Distributed (species with wild ranges both in Palearctic and Indomalayan). All species of the 4 range types were analyzed into 9 groups. The approximate fauna boundary could be drawn along Yangtze River,and there was an evid nt tr nsit onal one, ith t e nor hern orde alon the orth rn sl pe of Dabieshan Mountain - Lu'an City - Shucheng County - Hefei City - Dingyuan County - Lai'an County, and southern border along the north of Dongzhi County - Guichi City - Qingyang County -Nanling County - the northern of Xuanzhou City - Guangde County.
