摘要
研究了具有三个阶段 :幼年、成年、老年的阶段结构单种群生长模型 ,得到了该模型平衡点的稳定性的条件 。
In this paper,we consider a stage structure populations model with three lift stages, immature, mature and old. We obtain the conditions for stability of equilibrium and estabilish the sufficient conditions for the existence of a globally asymptotically stable of positive equilibrium of the model.
