通过对最大的大熊猫(Ailuropoda melanoleuca)圈养种群——中国保护大熊猫研究中心的圈养种群的研究,总结了圈养大熊猫的繁殖生物学特性,编制了大熊猫的生命表。大熊猫是季节性繁殖的动物,每年春季3~4月发情交配,8月(30.49%)和9月(48.88%)产仔,每胎平均产仔1.5只,圈养繁殖大熊猫的雌雄比为1.1:1。大熊猫的妊娠期和幼兽的初生体重变化很大,分别平均为139.8天和142.6g。性成熟的年龄,雌性是5.7±1.1岁,雄性是5.8±0.58岁。根据圈养大熊猫的生命表计算出圈养种群的净增长率R0为0.209,世代周期T为9.187年,内禀增长率r为-0.170,周期增长率λ为0.844。
REPRODUCTION AND LIFE TABLE OF CAPATIVE POPULATION OF GIANT PANDA (AILIROPODA MELANOLEUCA)
Giant panda is seasonal breeder and has marked mating season from March to April and birth season from August (30.4%) to September (48.88%),and on average produces a litter of 1.5 pups with a sex ratio (female : male) of 1.1∶1. Female (n=15) giant pandas were mature at the age of 5.7±1.1 years while the males (n=3) at 5.8±0.58 years. The study showed a wide range in gestation period and infant body weight and on average they were 139.8 days and 142.6 g. Life table constructed from the dead specimens on period from 1936 to 1999 of captive population of giant pandas revealed that the net reproductive rate (R0) was 0.209,the generation length (T) 9.187,the innate rate of change -0.170,and the fractional rate of length (λ) 0.844.
