Permanence and Global Asymptotic Stability for the Three-Species Predator-Prey Patch System

利用微分不等式技巧及比较原理 ,研究了具有HollingⅡ类功能反应的非自治的 3种群捕食者 食饵扩散系统的持久性和全局渐近稳定性问题 ,建立了一些新的判据 。

By employing the method of differential inequalities and comparison principle, permanence and global asymptotic stablility for the system of three species predator prey diffusion system with Holling Ⅱ functional response are studied. Some new criteria are established. The system considered here is the case that the preys is diffusive in two paths.
