摘　　要：赤腹松鼠剥食树皮的行为对林木危害严重,根据野外长期的观察和研究发现,赤腹松鼠在剥落树皮上遗留下来的上门齿齿印间距具有个体差异,可以用作个体识别的依据.对2003年监测样地内赤腹松鼠在剥落树皮上的齿印间距测量记录,并统计分析以估计赤腹松鼠的个体数量.结果表明:种群数量与危害率的相关系数为0.876,P=0.01,表现出很强的正相关关系;显示在较小面积内,该方法可以用来估计赤腹松鼠的个体数量.同时对该方法的基本条件和局限进行了讨论.A survey method for Callosciueus erythraeus population size was developed. Because different individuals of C. erythraeus have different upper tooth dental marks, its dental marks were studied using the peeled tree barks by C. erythraeus, and these data were analyzed by one-way ANOVA and multiple comparison to estimate the population size of C. erythraeus in 2003. The result indicates that the method can be used to estimate the population size of C. erythraeus in relatively small area. Fig 2, Tab 4, Ref 10
