. In the paper, we investigate a three-species food chain model with diusion and ratio-dependent predation functional response. We mainly focus on the co-existence of the three species. For this coupled reaction-diusion system, we study the persistent property of the solution, the stability of the constant positive steady state solution, and the existence and non-existence of non-constant positive steady state solutions. Both the general stationary pattern and Turing pattern are observed as a result of diusion.,Our results also exhibit some interesting eect,of diusion,and functional responses on pattern formation. Key words: food chain model, diusion, ratio-dependent functional response, station-
