中文摘要：
研究脉冲捕获捕食者与食饵具阶段结构的捕食-食饵模型.利用频闪映射理论,得到食饵灭绝的周期解是全局吸引的;运用时滞脉冲微分方程理论,证明了此系统是持久的.本文的结论为生态保护提供了可靠的策略依据.
英文摘要：
In this work,we investigate a predator-prey model with impulsive capturing predators and stage structure on prey.Using the theory of stroboscopic map,we obtain the prey-extinction periodic solution is globally attractive.By the theory on the delay and impulsive differential equation,we prove that the investigated system is permanent.Our results provide reliable strategy basis for the zoological protection.
