摘要
对一个具有HollingⅣ类功能性的非自治扩散捕食系统进行了研究,得到了系统一致持久生存的充分条件;并且当系统是周期系统时,得到了系统周期解存在的唯一、全局渐近稳定的充分条件.
The persistence for a nonautonomous prey-predator system with HollingⅣ functional response and diffusion is considered in this paper, and sufficient conditions for the persistence of the system are obtained. Also, when the system is periodic, some sufficient conditions for the existence and asymptotic stability of a periodic solution of the system is given.
