Abstract: By studying on the time budgets of white-headed langur,presbytis leucocephalus,the interior and envionmental factors which caused the time budgets of the population were discussed.This factors changes the time budgets of the population might largely influence the energy requirment of the population and theanimal of each age-sex classes. The result of analysis showed that the time budgets reflected the comprehensive effects of the factors on the population.The difference of time budgets of northern and southern populations of white-headed langur in southwestern of Guangxi Province is due to the different of the geographical area and the protective conditions of vegetation According to the behavioral factors observed, movement correlated most significantly to rest. The structure of the group caused the differences of the time budgets in the agesex classes.

摘要: 通过白头叶猴活动时间分配的研究,探讨引起种群活动时间分配的内在和环境因素。这些因素通过群体及各性别年龄组能量的不同需求改变其活动时间分配。分析结果表明,动物活动时间分配反映各种因素对群体的综合作用。作者推测,在白头叶猴分布区的南北种群间,因地理位置及植被保护状况的差异可能有不同的活动时间分配。在所观察的几个行为因子中,运动和休息相关性最大。群体本身的结构也造成群内各性别年龄组间活动时间分配的差异。
