  • Abstract
    In this paper, we present a spatial version of the Holling-type II predation-diffusion model which contains some important factors, constant harvest rate on prey, noise on predator. From the numerical results, we know that noise can induce instability and enhance the oscillation of the species density. Our results show that the noise and harvest play a prominent role in the predation-diffusion model.
