Our objective is to investigate its spatial dynamics, namely, the sharp criteria for persistence or extinction and the limiting behaviors of solutions with respect to advection rate. The main conclusions can be summarized as follows: (1) The existence/nonexistence, uniqueness and stability of nontrivial stationary solutions are obtained. To be specific: (3) The limiting behaviors of solutions with respect to advection rate are considered. It tells us that a sufficiently large directional motion will cause the species extinction in any situations. (4) The numerical simulations verify our theoretical proof and show that the advection rate has a great impact on the dynamic behaviors of species.
