摘　　要：1998和2000年,用样线法对巴塘县矮岩羊种群进行了研究,共发现矮岩羊158只40个集群,平均集群大小为(3.95±1.92)只,集群的大小在春夏季之间没有显著差异(P=0.45>0.05,df=38);单因素方差分析显示,矮岩羊集群大小在不同的年份具有显著差异(P=0.0153<0.05,df=62);多种比较发现,2000年矮岩羊集群的大小与1997年具有极显著差异(P=0.0041<0.01,df=60).研究结果显示,矮岩羊集群大小有逐年减小的趋势,其原因可能与栖息地的破碎化和人类活动的不断增强有关.The dwarf blue sheep Pseudois schaeferi, currently listed as Endangered （A2d, B1 ＋ 2e） by IUCN （1996, 2000） and classified in China＇s list of protected species, only inhabits China and a little is known about its population. In 1998 and 2000, the population was surveyed in the line transect method, and 158 individuals and 40 groups dwarf blue sheep were found. An average group size was （3. 95±1.92）. The population Group size between Spring and Summer are no different（P= 0.45〉0.05 ,df = 38）. But ANVOA shows there was significant difference in group size from 1997 to 2000 （P=0.0153〈0.05,df=62）, multi-comparison analysis presented that the group size between 1997 and 2000 approached extremely significant different（P=0.0041（0.01 ,dr=60）. All the results indicate the group size of dwarf blue sheep is reducing year by year.
