摘要
讨论有放养的第 类功能性反应的捕食链非自治系统 ,应用比较定理和不动点定理及 V函数法 ,在一定条件下证明该系统存在唯一的全局渐近稳定的正周期解 .
In this paper a nonautonomous food chain system with Ⅱ type functional response and graze is considered.The existence,uniqueness and global asymptotic stability of a positive periodic solution for the system are proved by the comparison theorem,fixed point theorem and V-function method.
