摘　　要：该文考虑了一类非局部时滞的SVIR反应扩散模型.通过构造合适的Lyapunov泛函,当基本再生数R_(0)>1时,证明了模型的正平衡点是全局吸引的,所得结果推广了一些已有的结果.In this paper,by using Lyapunov functional,we prove the global attractivity of the endemic equilibrium for a nonlocal delayed and diffusive SVIR model when R_(0)>1,which cover and improve some known results.

关 键 词：SVIR模型 空间异质 LYAPUNOV泛函 全局吸引性
