摘　　要：利用扫描电镜技术对狼头部和背部针毛的表面超微结构进行了观察和比较研究。结果表明,狼的头部针毛和背部针毛近似为梭形,2种针毛对应的典型部位之间在鳞片类型、游离缘平滑度、高度、密度等因素上存在一定差异。其中头部针毛和背部针毛的近根部分之间的高度、密度差异极显著;主体部分之间、近梢部分之间的高度差异不显著,而主体部分之间的密度差异极显著,近梢部分之间的密度差异不显著。这将为狼的形态学及分类学研究提供一定的参考。Surface uhrastructures of head needle hair and back needle hair of Canis lupus were observed and studied by scanning electron microscopy （SEM）. The results showed that the shape of the two kinds of needle hairs were fusiform. There were certain differences in the type of squama, the smooth degree of dissociated edge of squama, the height of squama and the density of squama between corresponding typical parts of the two kinds of needle hairs. First, there were highly significant differences in height and density between the near root part of head needle hair and the near root part of back needle hair. Second, there were no significant differences in height between the two main parts and between the two near ending parts. But while density showed highly significant differences between the two main parts, it showed no significant difference between the two near ending parts. The results can provide certain basic data for morphological and taxonomic research of Canis lupus.
