| 摘 要： | 粪便咬节是大熊猫数量调查中最常用的指标。然而，大熊猫在主食竹叶的季节有时在粪便中未留下咬节而使数量调查难以进行。为此，本文对大熊猫粪便宽径与咬节平均长度的关系进行了初步探讨。结果表明，大熊猫粪便宽径呈正态分布，同一个体的含咬节粪便与全由竹叶组成的粪便在宽径上无显著差异。大熊猫咬节平均长度与粪便宽径存在显著的回归关系。在不考虑年龄的情况下，粪便咬节平均长度与粪便宽径的回归方程为:Y=0.38X十14.40。成体和亚成体组的粪便咬节平均长度与粪便宽径的回归方程为:Y=0.22 X+22.79。年龄对大熊猫粪便咬节平均长度与粪便宽径的回归关系有显著影响。

| Abstract: | A preliminary study on the correlation between fecal width and average length of bamboo stem fragments in feces of giant pandas was conducted in Fengtongzhai Nature Reserve. The distribution of fecal width of the giant panda is normal, and no significant difference was detected between bamboo-stem-fragment feces and leaf feces from the same individuals. Significant regression correlation exists between fecal width and average length of bamboo stem fragments in feces of the giant panda. Without age concerned, the regression equation between fecal with and average length of bamboo stem fragments is Y=0.38X+14.40. This regression equation was significantly different from that for the adult and subadult group (Y= 0.22 X + 22.79). The results reported here has important significance for future census of wild giant panda population. |
