摘要
基于生物学和常微分方程的理论与方法,对一类具有阶段结构和脉冲投放的食饵-捕食系统进行了研究.通过脉冲比较定理,得到了系统食饵灭绝全局吸引的条件,以及系统持续发展的条件.
By using theories and methods of biology and ordinary differential equation,the predator-prey system with stage-structure and impulsive perturbations is established.By using the impulsive comparison theorem,sufficient conditions which guarantee the global attractivity of pest-extinction periodic solution and permanence of the system are obtained.
