摘要
对具有三个年龄阶段单种群自食阻滞模型,讨论了其正解性、平衡点、及平衡点的稳定性,得到平衡点存在和稳定的充分条件.
This paper discussed the retarders＇ models for single species with three life history stages and cannibalism. The properties of stationary, its equilibrium point and stability were analyzed. The sufficiency of the existence of the positive stationary solution and its stability were obtained.
