| Abstract: | In this paper,the author consider the reaction-diffusion system with initial and boundary conditions modelling the behavior of the competing species with constant stocking and a small diffusion rates.The upper and lower solutions methods is used to study the growth and extinction behavior and work out the parameters environment. |
