摘要
讨论了一类非自治具有第三类功能性反应的两种群捕食──食饵系统,食饵种群可以在两个斑块间扩散,而捕食者在两个斑块间无障碍物,证明了在适当的条件下,系统是持续生存的;若系统是周期系统,则在适当条件下。
A nonautonomous prey-predator system with HollingⅢ funtional response is discussed in this paper,where the prey can diffuse between two patches of a heterogeneous environment with barrior,but for the predator,the diffusion does not involve a barrior between patches.It shows that under appropriate condition,the system is permanent,furthermore,sufficient conditions are derived that guarantee the existence of a unique positive periodic solution which is global asymptotic stability.
