报告摘要：We are concerned with several reaction-diffusion SIS epidemic models in advective heterogeneous environments, and investigate the combined effect of spatial heterogeneity and individual dispersal on dynamics of infected diseases.Threshold- type results on the global dynamics in terms of the basic reproduction number are established. We further investigate the effects of diffusion, advection and mechanism on asymptotic profiles of the endemic equilibrium. The individuals concentrate at the downstream end when the advection rate tends to infinity. As the diffusion rate of the infected individuals tends to zero, the density of the infected may vanish on the habitat. The results may provide some implications on disease control and prediction.
