摘　　要：川金丝猴Rhinopithecus roxellana是我国特有的濒危物种。通过对全世界785只圈养川金丝猴的年龄分布、繁殖率、性比进行统计分析,编制圈养川金丝猴种群的生命表,绘制死亡曲线及存活曲线,计算川金丝猴的内禀增长能力。结果显示:圈养川金丝猴的寿命期望值较长,死亡率低,种群数量波动小,具有相对稳定的生态学特征;净增殖率、内禀增长率和周限增长率分别为2.674 6、0.095 28/年和1.100 0,说明圈养川金丝猴种群目前仍存在上升的空间,种群结构整体上相对稳定。The life table,mortality curve,survival curve,and innate increase capacity were estimated through analyzing the age structure,reproductive efficiency and sex ratio of 785 captive golden snub-nosed monkeys（ Rhinopithecus roxellana）from worldwide. The results showed that captive R. roxellana had long life expectancy,low mortality and small fluctuations of population numbers,and this suggested that captive R. roxellana had relatively stable ecological characteristics. Furthermore,the net reproductive rate,innate rate of increase and finite rate of increase were 2. 674 6,0. 095 28 / year and 1. 100 0,respectively. All of those factors indicated that captive R. roxellana was a relatively stable population up to date.
