报告摘要：This paper is concerned with the dynamics of a waterborne pathogen model with spatial heterogeneity and general incidence rate. We first establish the wellposedness of this model. Then we clarify the relationship between the local basic reproduction number
and the basic reproduction number .
It could be seen thatplays an important role in determining the global dynamics of this model. In fact, we show that the disease-free equilibrium is globally asymptotically stable when 
. If 
, then the disease-free equilibrium is globally asymptotically stable under some assumptions. In addition, the phenomena of uniform persistence occurs when 
. We also consider the local and global stability of endemic equilibrium when all the parameters of this model are constant. In the case , we further establish the existence of traveling wave solutions of this model. Moreover, we provide an example and numerical simulations to support our theoretical results.
