Abstract: China has a comparatively rich chiroptera fauna comprising 6 families, 29 genera and 90 species, contituting approximately 10% of the total number of species of the order in the world. Five families are considered as belonging to the tropical and subtropical representatives. Of the bat species of China, 20% are primarily Palaearctic, 71% primarily Oriental, and 9 % are both Palae-arctic and Oriental. Approximately 17% are endemic, their distribution being mainly confined to China.By using the formula of the index of faunistic congruence (Wallin,1969)¹), i. e., I_a,b = √P_a→b ·P_b→2, the bat faunal composition in the seven zoogeographical regions of China are compared with one another as well as the bat fauna of China as a whole, and of individual regions seperately with that of Japan.The results show that ( 1 ) the index for the bat fauna of N. -E. China Region with that of Mongolian-Xinjiang Region is 52 indicating the close relationship between the two fauna; (2) the bat fauna of Qinhai-Xizang (Tibetan) Region is quite similar to that of Mongo-Xinijiang Region (I = 59) 5 (3) the bat fauna of C. China Region is more similar to that of S. China Region than any of the other regions (I=48); (4) the index of faunistic congruence of the bat fauna of N. China Region and that of S.-W. China Region with their adjacent zoogeographical regions show that these two regions constitute the transition of the bat fauna from "southern" (Oriental) to "northern" (Palaearctic) Realms;(5) the index of bat faunistic congruence of China with that of Japan is 41,while among the Chinese Zoo-geographical Regions, the bat fauna of N.-E. China Region is most similar to that of Japan, having an index of congruence of 52, higher than that of any other regions. This figure shows the close affinity of the bat faunas of N.-E. China and Japan.
