草原生产者——消费者动力学模型的定性分析

Qualitative Analysis about the Dynamic Model of Steppe Producers and Herbivores

本文对草原生产者——消费者的二级系统的一般动力学模型进行了定性分析,得到非负解的整体存在性、零解的全局稳定性以及正平衡解的存在性。

In this paper,a model about the steppe producers and herbivores with the qualitative method was discussed and.gained the global existence, the stability of the triviol solution were gained In some conditions,it was proved that there was at least one positive solution for the equilibrium equation.
