摘　　要：利用红外相机技术于2014年10月—2015年10月在贺兰山国家级自然保护区对岩羊(Pseudois nayaur)集群行为进行研究,探究岩羊集群类型与集群规模出现频次及其冷暖季间的变化规律。共观察到岩羊2771群次,总计4942只次,平均集群大小为(1.78±1.49)只,最大群20只,最小群1只。集群类型共6种,分别为单个雄性、单个雌性、母仔群、雄性混合群、雌性混合群和雌雄混合群,其中,单个雄性出现996次(35.94%);单个雌性出现675次(24.36%);母仔群322群(11.62%),790只次;雄性混合群243群(8.77%),703只次;雌性混合群129群(4.66%),323只次;雌雄混合群406群(14.65%),1455只次。总的来看,各类型集群出现频次存在显著差异(P<0.001),不同集群类型出现频次在冷暖季间也存在显著差异(P<0.001)。岩羊在冷暖季均以单个个体出现情况较多,集群大小在冷暖季间无显著差异,不同集群类型群平均大小和群大小在冷暖季间也均无显著差异。This study investigated group patterns of blue sheep(Pseudois nayaur)in Helan Mountains from October 2014 to October 2015 by using infrared camera technology.It explored the frequency and seasonal changes of group type and size of blue sheep.A total of 4,942 individuals belonging to 2,771 groups of blue sheep were observed.The average group size was 1.78±1.49,varying in between 1 and 20.There were 6 types of groups,which were solitary male,solitary female,ewe-lamb group,male group,female group and female-male group.Solitary male and solitary female accounted for 35.94%and 24.36%of the total groups.The rest were made up of ewe-lamb group,male group,female group and female-male group with the respective percentages of 11.62%,8.77%,4.66%and 14.65%.The frequency of occurrence differed significantly among group types(P<0.001).And the frequency of occurrence of different group types had significant seasonal discrepancies in cold and warm seasons(P<0.001).Blue sheep were mostly solitary in both cold and warm seasons.However,there was no significant difference in group size between the two seasons.In addition,the mean group size and group size of different group types were not significantly different between cold and warm seasons as well.
