讨论了两斑块间脉冲扩散的单种群动力学模型,利用离散动力系统频闪映射理论,得到了种群持续生存的充分条件.结论31,1~了现实的生物种群动力学性质,也丰富了脉冲微分方程理论.
In this paper, we investigate the dynamical behaviors of a single population model with impulsive diffusion. The sufficient condition of system permanence is obtained by the discrete dynamical system determined by the stroboscopic map. Our results depict the dynamical property of the practical biological population, and enrich the theory of impulsive differential equation.
