摘要
Abstract
According to the trinity idea of habitat protected on "forest-bamboo-giant panda", a "forest - bamboo - giant panda" nonlinear dynamic model is established with due consideration for deforestation. The existence of periodic solutions of the dynamic model can be proved. A threshold value in deforestation is thus obtained. That is, when the intensity of deforestation is beyond a given threshold, the giant panda population will be almost extinct even though some forest still remains. When the intensity of deforestation is within a given threshold, an ecological balance among "Forest-bamboo-giant panda" will keep for them to continue to exist.关键词
