摘　　要：研究人口流动性对具有斑快结构的感染性疾病传播与扩散的影响,讨论了具有斑块结构感染性疾病SIS模型的全局稳定性,得到了该模型基本再生数的倍增效应．An SIS model for an infectious disease in population movement is formulated and analyzed. The model is used to assess the impact of observed difference in travel on the spread of the epidemic. The disease free equilibrium and endemic equilibrium are also discussed. The result show that infectious disease,and even more so when interconnected to other ones and forming a system,can have a multipier effect on the epidemic.

关 键 词：感染性疾病模型 基本再生数 全局稳定性 人口流动
