【Abstract】 Up to now, China has recorded the existence of the Black Gibbon, White-browed G bbon and White-handed Gibbon. Black Gibbon had once distributed extensively in the tropical or tropical rain forests in Yunnan, Hainan Island and Guangsi. For various reasons, only about 30—40 Hainan Gibbons remain alive at present. During the early period of the century there were about 2000 distributed in the primeval forests of two thirds of counties on the island. Now they only occur at very isolated spots of Changjiang, Baisha and Qiongzhong counties. They are on the verge of extinction within an area of about 100—200 square kilometres.更多还原
