Abstract: Study of seasonal home range of Thibetan Monkey was conducted in southwest stop of Huangshan Mountain，Anhui Province(118°19′E， 30°29′N) for 182 days (October,1985, November，1987)．There were 23 individuals(♂11,♀12)of Yulinkeng Troop in October,1985,and by November,1987,there were 33(♂16,♀17)．The Yulinkeng Troops home range included evergreen， evergreen and deciduous broadleaved mixed forests，with an area of 6km²．
Region's utilization frequency was related to the food abundance (table 3,4). In our research，region A and B (with the area of 0.75km² ) were utilized frequently.C and D (1.5km²) usually，and E (3.75km² ) generally．
The home range size of this troop changed seasonally．The Autumn size Was 3.62km²
contented 55% of evergreen forest,the summer size 1.02km² 24% of evergreen forest，the spring and winter 2.75 and 2.5km^2,55% and 65% evergreen forests respectively(see Fig.3,4).The monkeys had the longest daily moving distance,2.18km in summer,the shortest one,1km in winter,and 1.2 and 1.8km in spring and autumn．
The Yulinkeng Troop had a home range larger than that of M.fuscata and M.mulatta (see table 6),showing a lower utilization of home range than the laters．It also showed that the Thibetan Monkeys selected their foods in very narrow range．They must move a long distance to find foods．We considered that the monkeys were not so adaptive to wide environments．It might beoneof the reasons why this species distributed in small habitat and few quantities．
The Yulinkeng Troops home range had the highest altitude of 1310m,below the height of 8OOm where there was the farming area，so the home range only had a height of 40Om.Compared w ith other troops，the Yulinkeng Troop had its speciality and without vertical migration．The monkey's summer food were mainly the leaves of deciduous broad-leaved trees．Lacking of these trees in their home range，the monkeys had to move a long distance to find enough food．It meant that thetroop was capable of adjusting itself to adapt envirement．We considered that the characteristic of the utilization of seasonal home range was a kind of life pattern of the Thibetan Monkey in adapting its environment.
