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.
