【Abstract】 The asymptotic behavior of a strengthen type predator prey mcdel with stage structure is studied. And the sufficient conditions for the predator population extinct and uniform persistent are obtained. Moreover, the global asymptotic stability of the positive equilibrium is found by constructing suitable Lyapunov functions.更多还原
