研究一类具有阶段结构和扩散的非自治捕食一食饵系统,其中食饵具有阶段结构,捕食者能在两斑块中扩散,通过构造合适的Liapunov函数,得到了该系统存在唯一一个全局渐近稳定的概周期解的充分条件.
This paper considers a kind of nonautonomous predator - prey model, in which preys are with stage structure and the predator with two patches. It is obtained that under some conditions the system has a unique globally asymptotically stable positive almost periodic solution by using Liapunov function.
