摘要
从2007年3月9日至4月14日，调查了高黎贡山赧亢的白眉长臂猿的食性和时间分配，旨在为该物种的栖息地保护和食物资源的管理提供指导。观察时，将白眉长臂猿的行为分为取食、移动、休息3种活动类型，利用瞬时扫描取样法取样记录，并记录取食种类及部位。白眉长臂猿春季取食植物种类共有10种，其中果实类植物3种，果汁类植物1种，嫩叶类植物6种。相对其它灵长类而言，其春季的食物多样性较低。白眉长臂猿移动、休息和取食的时间分配分别为33％、35％和32％，较叶猴属动物休息少，移动多。赧亢的白眉长臂猿1天中有3个觅食高峰期，9：00～10：00为第1个觅食高峰；11：00～13：00为第2个觅食高峰；16：00～17：00为第3个觅食高峰。而孟加拉国Lawachara的白眉长臂猿仅在早上有两次觅食高峰。这种差异可能是不同区域的白眉长臂猿对环境的适应结果。
From March 3rd to April 14th 2007, an investigation of the diet and time budget of hoolock gibbon Hoolock hoolock was conducted at Nankang in Gaoligongshan Mountains. The result of this study could provide a clue for habitat protection and food resource management for this species. When observing in the field, the behaviors of hoolock gibbon were classified into feeding, moving and resting. Scanning samples method was applied when recording their behaviors. Meanwhile food and their feeding part were recorded. Hoolock gibbon fed 10 botanic species in spring, including three fruit species, one juice species and six young leaves .species. Comparing with other primates, the diversity of food species was less. The time budget percentage of feeding, moving and resting in hoolock gibbon was 33% , 35% and 32% respectively, which was lower percentage in resting and greater in moving than Presbyti.s. Hoolock gibbon had 3 feeding peaks during a day at Nankang, 9：00 to 10：00 was the first feeding peak, 11：00 to 13：00 was the second, and 16：00 to 17：00 was the third. However, the hoolock gibbon in Lawachara of Bangladesh only had 2 peaks limited in morning during a day. The feeding peaks differentiation of hoolock gibbon in different areas might be the results of adapting to the different environment.
