摘要
本文总结了作者1987年10月至1989年3月多次对云南西南部地区黑长臂猿(Hylobates concolor)考察的结果。各种群均生活于海拔2,000～2,700米的中山山地湿性常绿阔叶林中,以无量山数量最多,约117～144群,哀牢山可能次之,邦骂山和永德大雪山十分稀少。被观察的猿群均属小群体,平均3.0±1.4只(N=12,范围=2～5),为一夫一妻制。经深入观察其中一群表明,日活动时间达576±30分钟(N=5,范围=615),其中鸣叫占3％;游走占14％;取食占33％;休息占50％;日行程平均795±153米(N=13,范围=600～1,100);家域约44～49公顷,平均每天利用7.4公顷。上述结果与其他种及其他研究者的结果作了比较。
This paper is the results of the survey and study on the black gibbons (Hylobates concolor) in Southwest Yunnan from October, 1987, to March, 1989. The gibbon population investigated in the mid-mountain humid evergreen broadleaf forest between 2,000 to 2,700 meters above sea level, was made up of 117 to 144 groups in Mt. Wuliang, and maybe next in Mt. Ailao, and few in Mt. Banma and Mt. Daxueshan. All the groups observed in these area were small, averaged 3.0±1.4 (N = 12, range = 2 ~ 5 ) in size, and seemed to be monogamous. According to the observations on one group in Mt. Wuliang, the total amount of their active time was about 576 ± 30 minutes (N = 5 , range = 540~ 615), among them 3% for calling (15.8), 14% for traveling (73.3), 33% for feeding (180.8) and 50% for resting (273.3). The average day range length was about 795 ± 153 meters (N = 13, range = 600~1,100), and home range was about 44-49 ha, in which 7.4 ha was utilized everyday. The results above have been compared with that of other species.
