摘要
研究了一类具有阶段结构的非自治的捕食-食饵系统的渐近性质,得到了在适当条件下该系统的持久性,对应周期系统正周期解的存在性、唯一性以及全局渐近稳定性.
We study the amyptotic properties of the solution for a class of nonautonomous stage structured predator prey systems. It is shown that the system is permanent under some appropriate conditions, and sufficient conditions are established for existence uniqueness and stability of positive periodic solutions with respect to the corresponding periodic system.
