In this paper,we investigate a discrete semi-ratio dependent predator-prey system with Holling IV type functional response.For general nonautonomous case,sufficient conditions which ensure the permanence and the global stability of the system are obtained.Meanwhile,we discuss the existence of the positive periodic solution and global stability of the system. 相似文献
