摘　　要：研究具有时滞和扩散的Beddington-DeAngelis功能性反应的捕食-食饵模型,利用重和度理论探讨了此模型在周期情形下周期解的存在性.　In this paper,a non-autonomous dispersal-delay predator-prey system with Beddington-DeAngelis functional response is studied.By using the coincidence degree theory,a set of easily verifiable sufficient conditions are derived for the existence of positive periodic solutions of the proposed model.
