根据“大熊猫、主食竹和林木”三位一体栖息地保护理念，建立了一个描述“大熊猫、主食竹和林木”的非线性动力学模型，并且考虑了森林砍伐的影响．能够证明这个动力学模型存在周期解．获得了一个森林采伐的阈值，当采伐强度超过给定的阈值之外时，即使仍然有残余的森林，大熊猫种群将最终趋于绝灭．当采伐强度在给定的阈值之内时，在大熊猫、主食竹和林木的生态系统中保持一种生态平衡，大熊猫、主食竹和林木三者持续生存．

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.
