摘要
研究了一类带阶段结构的食饵—捕食模型的渐近性态 ,建立了种群一致持续生存和灭绝的条件 ,通过构造V函数证明了正平衡点的全局稳定性 .
The asymptotic behavior of a strengthen type predator prey mcdel with stage structure is studied. And the sufficient conditions for the predator population extinct and uniform persistent are obtained. Moreover, the global asymptotic stability of the positive equilibrium is found by constructing suitable Lyapunov functions.
