| Abstract: | Using the upper-lower solution method of reaction-diffusion systems, a class of multi-species cooperating model is studied and the conditions for the existence of globally stable positive constant equilibria are got. Also a class of multi-species competitive model is studied and the conditions for the permanence of the solutions are got. |
