讨论了一类具有3个成长阶段的捕食.被捕食模型.利用比较原理,得到了系统永久持续生存的充分条件,同时通过构造Lyapunov函数,给出了系统全局渐近稳定的充分条件.
A predator-prey model with three life stages is investigated. Sufficient conditions for permanence are derived by using comparable theorem. By constructing Lyapunov function, the conditions for global asymptotic stability of the system are presented.
