摘要 研究一类具有Beddington功能反应和放养的Lotka-Volterra扩散系统。证明了系统正周期解的存在性,并通过构造适当的Lyapunov泛函,给出了正周期解全局稳定的充分条件。 Researches a Lotka-Volterra diffusion system with Beddington function response and stock. Proves the existence of positive periodic solution for the system, and by constructing appropriate Lyapunov function, provides sufficient conditions for the global stability of positive periodic solution.
