摘　　要：为了解白马雪山国家级自然保护区岩羊种群的基本情况和活动规律,采用固定样线法、访谈法,结合红外相机观测,对2011—2016年期间曲宗贡区域的岩羊种群数量、分布情况、海拔梯度、日活动规律等方面进行调查研究。结果表明:该区域的岩羊种群数量平均值为107±5.6只,存在一定的年间种群数量波动,同时种群的雌雄个体活动存在社群分离现象。岩羊主要活动区域包括姬妞沟、姬妮沟、达瓦粗、粗瓦粗等地。另外,岩羊全年活动的平均海拔为4380±20.5 m,全年活动海拔跨度637 m,表现出了一定的季节性迁移行为。不同活动时间段,日活动节律变化存在显著差异。In order to understand the basic situation and activity law of the Pseudois nayaur population in Baima Xueshan National Nature Reserve,the fixed sample line method,interview method and infrared camera observation were used to investigate the population number,distribution,altitude gradient and daily activity law in Quzonggong area from 2011 to 2016.The results showed that:the average population size of Pseudois nayaur in this area was 107±5.6,there was a certain annual population fluctuation,and there was a phenomenon of community separation between male and female individuals.The main activity areas of the sheep include Jiniugou,Jinigou,Dawachou and Dawachou.In addition,the average altitude of annual activities of Pseudois nayaur is 4380 ± 20.5 m,and the annual activity altitude span is 637 m,showing a certain seasonal migration behavior.There were significant differences in daily activity rhythm among different activity periods.
