摘　　要：研究一类具有脉冲效应的害虫管理系统,讨论了系统的灭绝性和持续性,给出了系统灭绝和持续生存的阈值条件,并对所得结论进行了数值模拟.A pest management system with impulsive effect is studied in this paper. The extinction and permanence of system is discussed, and the conditions of the extinction and permanence are given. Furthermore, those results obtained in this paper are confirmed by numerical simulation.

关 键 词：脉冲效应 灭绝 持续 全局渐近稳定
