摘要
研究了一类具有阶段结构的食物链模型,分析了系统平衡点的稳定性,运用数值模拟展示了系统周期性振动,混沌等复杂的动力学行为,并分析了阶段结构对系统复杂行为的影响.
A class of food chain system with stage structure is studied. The stability of the equilibrium points is investigated, by using numerical simulations showing system periodic oscillation, chaos and so on complex dynamics behaviors, and has analyzed the stage structure to the system complex behavior influence.
