摘　　要：应用光学显微镜和扫描电镜技术,对贺兰山岩羊(Pseudois nayaur)颈部、背部、腹侧部、腹下部、臀部、腿部、蹄部7个部位冬毛及夏毛形态特征进行观察与比较。结果表明:除过鳞片花纹类型及排列顺序表现出一致性外,贺兰山岩羊7个部位冬毛和夏毛在毛长度、毛伸直长度、卷曲度、毛细度、髓质细度、毛髓质指数上均存在一定差异。贺兰山岩羊上毛髓质指数较高,除蹄部外,其它6个部位保持在90%以上。躯干部毛长度和毛髓质指数显著高于腿部和蹄部(P<0.05),主要起到保温功能。腿部和蹄部杂波型鳞片比例最大,皮质发达,主要起到保护功能。这将为贺兰山岩羊的形态学及物种鉴定研究提供一些基础资料。We observed the hair of blue sheep（Pseudois nayaur） in Helan Mountains using optical microscopy and scanning electron microscopy to compare morphology characteristics among neck,back,veutro,abdomen,hip,leg and hoof both in winter and summer.Seven different parts had similarity and consistency in scale types and the order of scale type arrangement.While there was difference in hair curled length,hair uncurled length,crimp ratio,medullary diameter of hair,diameter of hair,and medullary index of hair.The medullary index of hair in blue sheep was high,in addition to the hoof,the other six parts remained above 90%.The hair length and hair medulla index of the trunk were significantly higher than those of the legs and hooves（P〈0.05）,and the hair of trunk had main function in heat preservation.Legs and hooves,owning the largest proportion of irregular wave scale and cortex,had main function in protection.
