阶段结构种群动力学模型
The Models of Stage-Structured Population Dynamics
【摘要】 详述了近年来对阶段结构种群动力学模型的一些研究成果 ,及这类系统的持续生存、正平衡点稳定性及全局渐近稳定的条件 ,并讨论了扩散、传染病、环境污染等的影响 .
【Abstract】 Models of stage structured population dynamics were summarized.Guarantee the permanence,stability and globally asymptotical stability of positive equilibrium were obtained.The influence of diffusion,polluted environment and disease were discussed.
