摘要
在捕食模型中,考虑食饵与捕食者的阶段性结构,并考虑一类带Beddington-DeAngelis功能性反应的阶段结构捕食种群的持久性,运用微分方程理论进行分析,得到了食饵种群和捕食者种群都持久发展的参数条件.
A stage-structured predator-prey system with Beddington-DeAngelis functional response is studied in this paper.The conditions of permanence of the both populations are obtained by using differential equation technical.
