| 摘 要： | 在Jolly Seber法中 ,存活率为其核心参数之一。一些作者指出 ,采用Jolly Seber法估算标志重捕数据有时候会出现存活率大于 1的情形。本文就这一情形做了相应的分析 ,认为产生这一现象的原因为标志个体间不具有等捕性或等存活率所致。在设计标志重捕取样的野外调查中 ,应设法提高重捕率以增加估计精度

| Abstract: | The Survivorship estimation is one of the most important parameters in the Jolly Seber model. As it has been revealed by other authors, the value of the survival rate obtained by the Jolly-Seber estimation may exceed 1 in some cases. According to current analysis made on this problem, we found that it was due to fact that the unequal trappability and the unequal survival rate occur between the marked animals. In order to solve that problem, we should try to improve the recapture possibility to increase the estimating accuracy in the experimental design of capture recapture census. |
