Abstract：The giant panda was Chinese endemic endangered
species, and captivity was an important strategy for giant panda protection.
The fourth giant panda survey published by the state forestry administration
showed that the giant panda breeding protection work had gained gratifying achievements, and captive population scale developed rapidly.
To evaluate the relationship between the development of captive population and
the future growth trend, the survival curve of captive
giant panda more than 100 days old, life table, mortality curve, survival curve, and innate increase capacity
were estimated through analyzing the basic information of 990 captive giant pandas in the 2015 International
Studbook for Giant Panda. The results showed that, the number of survival giant
panda per year was more than 20 or even 30 from 2005, and more than 40 in 2013
and 2015. The captive giant panda had long life expectancy, low mortality
between the ages of 2 and 25, and the vast majority of captive individuals
could live to their biological age. All these findings suggested that the
captive giant panda has relatively stable characteristics in their natural
life; moreover, the net reproductive rate (R0),
innate increase capacity (rm)
and finite rate of increase (λ) were 2.248 4, 0.062 3 and 1.064
3, respectively. These results suggested
that the population of captive giant panda is a relatively stable, but still
has a large space for development.
