摘要
自2012年12月~2013年12月,利用红外相机技术及样线法首次对额仁淖尔苏木的盘羊生存现状进行研究。结果表明：该种群由3只成体（2♂1♀）2只亚成体（1♂1♀）和1只幼体（1♂）组成;平均每台红外相机的拍摄率为38%;以拍摄率作为衡量盘羊活动频率的标准,冬季盘羊的活动频率达到高峰,春季和夏季较为稳定,秋季降到最低。盘羊对水源点的利用强度占2%,肉食性野生动物占21%,家畜占77%;盘羊对隐蔽度的要求较高,占总生境的59%。
We used infrared camera-traps and transect survey to study the population of argali （ Ovis ammon） in the E＇ren Nao＇er region of Inner Mongolia, China for the first time from Decem- ber2012 to December 2013. The population consisted of 3 adults （2 ♂ 1 ♀ ）, two sub adults （1 ♂; 1 2 ） and a juvenile male. 38% of camera-trap photographs included images of Argali. Based on the frequency of argali photographs, argali had the highest frequency of activities in win- ter, the frequency of activities in summer was the same as spring, and the lowest frequency was in autumn. Two percent of photographs showed argali at water sources as compared to 21% for carnivores and 77% for livestock. Argali preferentially used habitats with cover, where the camer- a-trap capture rate was 59%.
