摘　　要：2007年8月至2008年7月,在广西崇左白头叶猴自然保护区选择一群白头叶猴全雄群作为观察对象,采用瞬时扫描取样法收集相关的行为数据,从中探讨群大小和组成对白头叶猴日活动节律和活动时间分配的影响。结果表明:白头叶猴全雄群的日活动节律表现为上午和下午的觅食高峰,中午进入长时间的休息期。全雄群一天中活动时间有48.7%用于休息,23.3%用于移动,18.5%用于觅食,用于玩耍、理毛和其他行为的时间较少,分别占日活动时间的7.2%、1.9%和0.4%。除用于玩耍时间外,它们用于其他活动的时间分配并未表现出明显的季节性差异。与雨季相比,旱季里全雄群花费更多的时间用于玩耍。分析表明,白头叶猴全雄群和两性群群大小和组成的差异明显影响着它们的活动时间分配。Behavioral data were collected from an all-male group of the white-headed langur（Trachypitheucs leucocephalus） between August 2007 and July 2008 at Guangxi Chongzuo White-headed Langur National Nature Reserve,Guangxi Province,China using the instantaneous scan sampling method.This study is to investigate influences of group size and composition on diurnal activity budgets of white-headed langurs.The results indicated that all-male group of white-headed langurs showed morning and afternoon feeding peaks,with a midday resting peak.Langurs spent ca.48.7% of their daytime resting,23.3% moving,18.5% feeding,7.2% playing,1.9% allgrooming,and 0.4% for other behaviors.There was no significant seasonal variation in most activity budgets,except for playing.They spent more time in playing in the dry season than in the rainy season.In addition the difference in group size and composition between all-male group and bisexual group influence their time budgets.
