| 摘 要： | 在先验信息下，确定动物总数和捕捉概率分别服从离散均匀分布和Beta分布，对捕捉与再捕捉试验推导了封闭总体中个体总数N的Bayes点估计与区间估计；另外，对多次重复的捕捉与再捕捉试验推导了个体总数Ⅳ的Bayes综合估计，最后对一个实例进行了分析。

| Abstract: | In this paper, Bayesian point estimate and interval estimate of animal number Nare obtained by means of prior information when animal number and capture probability obey discrete uniform distribution and Beta distribution; In addition, Bayesian synthetic estimate of population size N is induced basing on multiple capture-recapture, In the end, a real example is used to analyze the methods. |
