摘要

研究了一类具有一般传染率寄生虫宿主模型的全局性态.利用微分方程定性理论得到了宿主和寄生虫共同绝灭的条件;进一步得到了宿主和寄生虫共存即系统正平衡点存在的条件

证明了正平衡点只要存在一定是全局稳定的.

Abstract

The global qualitative behavior of a microparasite model with general incidence was studied.The extinction conditions of host and parasite are obtained by the method of the differential qualitative theory.Furthermore

the existence conditions of the positive equilibrium point of the system are derived.The conclusion

that the sufficient condition for global stability is the existence of the positive equilibrium point

is proved.
