Abstract: This paper deals with the bat species and their distribution in Huizhou region, Anhui Province.There are nineteen species belong to nine genera and four families, of which three are new records in this province. Their hibernation was observed, the humidity of hibernating sites,the relation between temperature and depth of the caves were under consideration .The relation between air temperature and body temperature of bats was found as a linear regression equation,Y = 0.616x+ 6.922(where x represents the air temperature,Y represents the body temperature).The respondences of bats to flashlight, sound as well as touch in hibernant period were studied.The pre-hibernation period is about one month from the first ten-days of November to the first ten-days of December. Their hibernant period is about 3—4 months.The overwintering bats in residential area demand the range of air temperature from 0 ℃ to 10℃,the humidity is 60%; the overwintering bats in caves demand the range of air temperature from 10℃ to 16℃, the humidity is 92.5—96%,The higher the cave temperature,the higher humidity is demanded by bats,
