摘要
本文研究单种群阶段结构生育脉冲的数学模型,通过研究其频闪映射所确定的离散动力系统,我们获得了生育脉冲的系统存在周期解及其稳定的阈值,阐述了阈值的生物意义.
Birth pulese mathematical model of a single-species with Stage-structure is studied. By studying the discrete dynamical system determinded by stroboscopic map we obtain an exact periodic solutions of system with birth pulses and threshold for their stability. We give the biology meaning of the threshold.
