广西藏酋猴种群数量、分布及威胁因素的分析

Survey on Population,Distribution and Threatening Factors of Tibetan Macaques(Macaca thibetana) in Guangxi,China

2013年4月至2014年11月,采用访问法、样带法与红外相机技术相结合,对广西境内的藏酋猴Macaca thibetana种群资源进行调查,结果表明:广西藏酋猴种群为27个,共(542±69)只,主要集中在桂东北片区的猫儿山、花坪和千家洞3个国家级自然保护区内,个体数量占广西藏酋猴总数的90.2%;九万山、大瑶山国家级自然保护区和龙滩自然保护区均仅发现1个猴群;原有藏酋猴分布记录的恭城县和荔浦县内并未发现猴群分布。红外相机监测发现猫儿山和花坪国家级自然保护区各增加1个猴群的记录,同时增加九万山和大瑶山国家级自然保护区藏酋猴的分布记录。栖息地破碎化、频繁的人类活动和盗猎行为可能是影响广西藏酋猴种群动态变化的重要因素。

The population size of Tibetan macaque （Macaca thibetana ）was estimated based on interviews, the field survey and camera traps from April 2013 to November 2014 in Guangxi.
