讨论了一类具有αi类功能性反应函数和反馈控制的捕食链模型,得到了系统永久持续生存的充分条件;通过构造Lyapunov函数,给出了系统全局渐近稳定的充分条件.最后建立模型说明所得结果的可行性.
A class of food-chain model with αi-type functional response and feedback controls is investigated.Sufficient conditions are obtained for the permanence of the model.Moreover,by constructing Lyapunov function,some conditions for global asymptotic stability of the system are derived.An example satisfying the conditions of the main results is given.
