摘要 本文基于综合害虫管理策略(IPM),对具有脉冲效应的 Lotka-Volterra 捕食与被捕食系统进 行了分析。证明了当脉冲周期小于某个临界值时,系统存在一个全局渐进稳定的害虫根除周期 解,否则系统是持续生存的,而且通过分析表明如果采取有效的化学控制策略,那么综合害虫管 理策略是最有效的。 A Lotka-Volterra predator-prey system concerning integrated pest management is proposed and analyzed. It is proved that there exists a globally asymptotically stable pest-eradication periodic solution when the impulsive period is less than some critical value. Otherwise, the system can be permanent. We obtain that our impulsive control strategy is more e?ective than the classical one if we take chemical control e?ciently.
