具有阶段结构非自治食饵——捕食者模型的研究

Study on a Predator-prey Model With Nonautonomous Stage-Structure

本文研究了一类非自治具有阶段结构的食饵———捕食者模型的解的最终有界性,持久性,并证明了周期系统的正周期解的存在、唯一性以及全局渐近稳定性.

In this paper,a predator-prey model with Nonautonomous stage-structure is discussed.We prove that the solutions of the model are ultimately bounded and persistent.Also the existence,uniqueness and the global asymptotic stability of the positive periodic solution are studied.
