摘 要: 本文讨论了一类食饵为广义Logistic生长,捕食者为具有Holling(I)型功能反应的数学模型:其中v>-1,而r1,r2,T,c,k,x均为正常数.文中利用微分方程定性分析方法,给出了这类模型的正平衡点存在,和各种平衡点的稳定性条件和稳定区域. This paper deals with a prey-predator model where predator is a generalized logistic growth,prey is Holling (I) type functional curve: are positive constants. This paper offers a qualitative analysis method of differential equations. It gives the condition for the existence of positive balance point, the stability condition and field of each balance point of the model.
