摘要
研究一类具食饵避难所的阶段结构捕食-食饵模型.通过详细分析模型的动力学行为,获得较小容量的避难所不影响种群的动力学行为,而较大容量的避难所有稳定性作用并且随着避难所容量的增大,可能导致种群灭绝.给出两个例子证明所获得的结论.
A stage-structured predator-prey model incorporating a prey refuge is investigated.By detail analyzing the dynamic behaviors of the model,we show that small refuge has no influence on the dynamic behaviors of the model and large refuge has the stabilize effect and increasing the amount of refuge can lead to population outbreaks.Two examples are carried out to illustrate the validity of our results.
