摘要
2010年1～2月,采用访问与实地调查相结合的方法,对云南无量山国家级自然保护区的西部黑冠长臂猿景东亚种进行第二次全面的群体数量与分布调查。结果表明:无量山现有长臂猿87群;东坡的群体数量多于西坡,南段多于北段;有15群长臂猿生活在无量山自然保护区外;无量山长臂猿群体的海拔分布范围为1900～2800m;经度分布范围为100°30′～100°50′E,纬度分布范围为24°17′～24°45′N;无量山自然保护区内的长臂猿群体分布密度为0.24群/hm2;近10年来,无量山长臂猿的群体数量在下降。
From January to February,2010,the populations and distribution of the western black crested gibbons（Nomascus concolor jingdongensis）living in Wuliang Shan National Nature Reserve were surveyed for a second time by interview and fieldwork.The results showed that 87 groups of gibbons lived in Wuliang Shan.More groups were distributed along the east slope than the west slope,the south section was more than the north section.Fifteen groups lived outside of Wuliang Shan Nature Reserve.An altitude of 1900~2800 m and longitude 100°30＇~100°50＇,as well as latitude 24°17＇~24°45＇ were the ranges of the groups＇ distributions.The distribution density of gibbon groups was 0.24/100 hm2 in Wuliang Shan Nature Reserve.The number of gibbon groups has decreased in the last ten years.
