摘要：
We study a spatial susceptible-infected-susceptible(SIS) model in heterogeneous environments with vary advective rate. We establish the asymptotic stability of the unique disease-free equilibrium(DFE) when R-0 < 1, and the existence of the endemic equilibrium when R-0 > 1. Here R-0 is the basic reproduction number. We also discuss the effect of diffusion on the stability of the DFE.
