景东无量山自然保护区黑长臂猿的数量与保护

无量山地处云南中部，为黑长臂猿（Ｈｙｌｏｂａｔｅｓｃｏｎｃｏｌｏｒ）的主要分布区之一。近年来国内外学者虽然对黑长臂猿进行了较多的行为，生态与保护研究，然而有关该地区黑长臂猿的数量估计却有很大差异（６６－３００群）如：蓝道英（１９８９）报道有６６－１４４群，Ｈａｉｍｏｆｆ等（１９８６）认为有２２５－２５０群，Ｂｌｅｉｓｃｈ等（１９９）也认为有较多的群体，达１６０－３００群之多，而Ｚｈａｎｇ等（１９９

POPULATION AND CONSERVATION OF BLACK-CRESTED GIBBONS ( Hylobates concolor jingdongensis ) IN WULIANG NATURE RESERVE, JINGDONG, YUNNAN

Population estimates of black crested gibbons in Wuliang Nature Reserve,Jingdong,Yunnan,China,with two techniques,average group density total area and average home rang forest coverage,produced quite similar results.The population was estimated around 115 groups in the Reserve.The paper also discussed the conservation problems of the Reserve.At present,the main threat to the gibbons is habitat fragmentation and population isolation.Thus,it is urgent to prohibit hunting and protect the habitat and forest corridors or habitat bridges.
