摘要
本文讨论了具有连续时滞和Ⅲ类功能性反应的非自治扩散竞争系统。此系统有两个种群两个斑块。其中一个种群可以在两斑块中自由扩散,另一种群被限定在一斑块中不能扩散。给出了系统种群的持续生存,周期解存以及全局吸引的充分条件。
In this paper,a nonautonomous diffusion competition system with continuous time delay and Ⅱtype functional response is studied.There are two species and two patches in the system.One of the two species can diffuse between two patches,and the other is confined to one patch.Sufficient conditions are established that guarantees the persistence of species,the existence and global attractivity of a periodic solution of the system.
