【Abstract】 Comparing the present giant panda (Ailuropoda melanoleuca) with the three kinds of fossil giant pandas(Ailurarctos lufengensis, A. microta, A. m. baconi and A. m. wulingshanesis), the paper has come to the conclusion that the change in body size is like this: smallest (A. microta)---biggest(A. m. baconi)---smaller (A. m. ) and the cause of this change has been analysed. From internal and external factors we can see that the giant panda is in danger. We must conserve the habitat of giant panda and fully exploit potentialities in breeding and rearing pandas in captivity in order to postpone the extinction speed.更多还原
