高黎贡山赧亢白眉长臂猿(Hoolock hoolock)春秋季活动范围变化

以云南省高黎贡山国家级自然保护区赧亢片区为研究地点，对1雌1雄1幼组成的白眉长臂猿家群展开为期4个月的持续跟踪.春季获得7个全天跟踪数据，秋季获得5个全天的跟踪数据，有效跟踪时间达184.5个小时.白眉长臂猿有相对固定的夜栖区和取食区，春季活动区域面积仅占秋季活动区域面积的45.9%.春季白眉长臂猿的夜栖区和取食区集中在草果种植区内.秋季白眉长臂猿的夜栖区和取食区则不在草果种植区内，比较分散.人类草果种植没有影响白眉长臂猿分布，但秋季草果采收却干扰白眉长臂猿取食和夜栖. 该结果为白眉长臂猿的有效保护和食物的供给提供理论依据.

Seasonal Changes of Ranging area by Hoolock Gibbon (Hoolock hoolock) at Nankang,Mt. Gaoligong between Spring and Autumn

Nankang District of GaoliGong National Nature Reserves was taken as research place, and four-month duration tracing was carried out for the activity area of a Hoolock gibbon family group composed of a female, a male and a child. Seven full-day tracing data were obtained in spring, 5 full-day tracing data were obtained in autumn, and effective tracing duration achieved 184.5 hours. Gibbon had relatively fixed feeding area and roosting area, and activity region area of Hoolock gibbon in spring was only 45.9% of activity region area in autumn. The night roosting area and feeding area of Hoolock gibbon in spring were centered in the grass and fruit planting area. The night roosting area and feeding area of Hoolock gibbon in autumn were not centered in the grass and fruit planting area and are more scattered, which indicates that human strawberry cultivation does not affect distribution of Hoolock gibbon, but grass and fruit picking in autumn disturbs feeding and roosting of Hoolock gibbon.
