| 摘 要： | 小相岭山系现存大熊猫约34只，数量稀少，且受到人为活动干扰强度较大，基因交流困难，整个种群处于濒危境地．本文运用VORTEX模型对该山系未来100a内大熊猫种群动态进行了模拟．结果表明：尽管从年龄结构上看小相岭山系大熊猫属于稳定型种群，但在考虑竹子开花和森林火灾的情况下，其近亲繁殖系数将在90a后达到1．0，该种群将于80a后灭绝．因此，对该地大熊猫采取更为有效的保护措施已经迫在眉睫．

| Abstract: | Nowdays,there are only about 34 giant pandas distributed in the Xiaoxiangling Mountains.Due to the small population number and the disturbance caused by human activities,it's difficult for individual and genetic exchange.The whole population is on the verge of extinction.We use Vortex software(version 8.21) to carry on population viability analysis in attempt to model the dynamic of future 100 years.We find that the inbreeding coefficient of giant panda population in the Xiaoxiangling Mountains will reach 1... |
