Amendment on The Life Table and Relevant Datum Indicators of Giant Panda

The life table of the giant panda was suggested by WEI Fu-Wen in 1989,who mainly based on the skull specimen collected in field and the result of age determination through incisor sections of known age panda specimen.However,in a review of recent literature.We noted 3 errors in analyses,all of which may lead to erroneous inferences (Harris et al.,1993),Therefore.According to the data on the age structures of wild giant pandas in Mingshan and Qinglai Mountains,and the age structure derived from the analysis on the skull specimen as well as the stable age structure in the giant panda populations in the two mountains,the proportions of the giant panda in different classes are calculated by using the relative equation of distribution density function on the ages of animal populations:f(x)=βe-βx (Hou et al.,1998).Then,the life table of the giant panda and its relevant numerical indexes were amended through synthesizing the research data and the main conclusions as follows:The mean life expectancy:3.995 years.After a half year of living.The mean life span increase to (10.36±1.15) years.The net reproductive rate (R0):1.05734.The mean time of per generation (T):12.156 years.The intrinsic rate of natural increase (rm):0.00459033.The finite rate of increase (λ):1.00460040.
