摘要
本文对非线性密度制约的具HollingⅡ型功能反应的食饵—捕食系统进行了定性分析,给出了唯一正平衡点全局渐近稳定和存在唯一稳定极限环的充分条件,参数的变化是大范围的。
This paper presents the qualitative analysis of the prey-predator system with Holling's type ll functional response and the nonlinear dependence of the densities of predator and prey. The sufficient conditions for existing the only stable limit cycle and those in which the only positive equilibrium point is asymptotic stable over; large range, lare obtained the changing range of parameters is wide.
