【摘要】 讨论与生物资源管理相关的具有阶段结构且捕食者具有脉冲扰动的食饵一捕食者模型,得到了食饵灭绝周期解的全局吸引和系统持久的充分条件,也证明了系统的所有解的一致完全有界.通过数值模拟验证了所得理论结果的正确性.所得结论为现实的生物资源管理提供了可靠的策略依据。更多还原

【Abstract】 A delayed stage-structured predator-prey biological resource management model with impulsive on predator is considered.Sufficient conditions which guarantee the global attractivity of prey-extinction periodic solution and permanence of the system are obtained.Numerical results show that the obtained conclusions are accurate.The results provide reliable tactic basis for the practical biological resource management.更多还原
