摘　　要：通过访问调查和野外调查两种方法对曾经分布于西双版纳北白颊长臂猿种群进行调查和研究。结果表明,北白颊长臂猿曾分布于西双版纳州勐腊县磨憨(尚勇)、勐满、勐伴、勐腊、瑶区、关累(麻木树)等乡(镇)及管委会区域内,但从20世纪50年代以来北白颊长臂猿种群分布范围逐年缩小。60年代勐腊县有北白颊长臂猿约615只,80年代约有142只,2000年之后已不足10只,种群密度和数量都呈下降趋势,而本次调查中,西双版纳地区没有发现北白颊长臂猿野生种群的分布。致危因素主要有:生境破碎化、猎杀、林下经济的发展等。种群保护及恢复途径有:加强北白颊长臂猿栖息地保护及巡护监测力度,做好自然保护区跨境联合保护工作,加强生物廊道建设,调整产业结构,转换经济增长模式,开展北白颊长臂猿回归方面的科学研究等工作。After interview and field investigation in Xishuangbanna, Yunnan Province where Nomascus leucogenyswas found, it is concluded that N leucogenys population was once distributed in Mohan Town （Shangyong Village）,Mengman Town,Mengban Town,Mengla Town, Yaoqu Village, Guanlei Town （ Mamushu Village） in MenglaCounty, Xishuangbanna. Since the 1950s the distribution range of population has been narrowed dowoi year by year. In Mengla County, it was found there were about 615 N leucogenys in the 1960s, about 142 in the 1980s, and fewer than 10 after 2000, indicating the decline trend of the population density and nN leucogenys found in Xishuangbanna area. The major threats for N leucogenys population are ： habitat fragmenta-tion ,hunting, and development of the economy, etc. . Approaches of population protection and recover a e recom-mended ：to strenghen the protection and monitorng of habitat of N leucogenys ; to canr out cross-border joint pro-tection ;to speed up the constrjiction of the biological cooidor; to adjust the industrial strjicture and transform eco-nomic growth mode; and to launch scientific research to help N leucogenys return to nature etc..
