two-prey one-predator system with a special Holling-Ⅱ functional response is dis-cussed. That w-periodic solution of the predator extinction is global asymptotically stable is proved by some new methods. Furthermore, by the comparison theorem of impulsive dif-ferential equation, the sufficient conditions are derived for the permanence and the existence of periodic solution of the system.
