| Abstract: | Some predator- prey systems of three species based on Volterm - model are studied in this paper. The stability and boundedness of solutions are investigated and the phase diagrams are described by theoretic analysis and numerical simulation. Some results are obtained with the system varying trends discussed under multi - condition. |

| Keywords: | nonlinear systems volterra- model equilibrium solution stability phase diagram |
