提出了一种在斑块环境下具有脉冲控制的害虫管理传染病模型。利用小振幅摄动法、矩阵谱分析和持续生存理论,研究了脉冲系统的绝灭和持久的动力学行为,得到了系统的动力学阈值R0。证明了当R0为1时,系统的周期消灭虫害解是全局渐近稳定的。此外,通过对两斑块情形的讨论,分析了分散控制和脉冲控制对系统动力学行为的影响。给出了一些数值算例,以说明所得结果的有效性和系统的复杂性,如混沌特性。
An epidemic model for pest management with impulsive control over a patchy environment is proposed in this paper. We investigate the dynamical behaviors on extinction and permanence and obtain the threshold value R0 of dynamics for the impulsive system by utilizing a small amplitude perturbation method, matrix spectral analysis and persistence theory. We prove that the periodic pest-eradication solution of the system is globally asymptotically stable if R0 1. Furthermore, by discussion on the two-patch case, we analyze the effects of the dispersal and impulsive control on dynamical behaviors of the system. Some numerical examples are given to illustrate the effectiveness of the obtained results and to demonstrate the complexity such as chaotic characteristic of the system.
