建立了三类具有不育控制的脉冲生育单种群模型。利用频闪映射给出了系统的周期解存在的充分条件;利用比较定理得到系统零解的全局渐近稳定性的充分条件;根据细致分析法得到系统解持续生存的充分条件。
In this paper, we propose contraception control single species models with impulsive Birth.Using the strobo-scopic map, we obtain the sufficient condition for periodic solution.Using comparison principle, the sufficient condition for globally asymptotically stable of zero solution is obtained.Lastly, the sufficient condition for persistence of system is obtained.
