| Abstract: | 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. |
