Permanence and Globally Asymptotical Stability of Periodic Predator-prey Systems with Holling Type Functional Response

The permanence and globally asymptotical stability for periodic predator-prey systems with Holling type functional response are discussed in this paper.By use of comparison principle,the sufficient conditions of the permanence of system were given.By means of constructing the Liapunov function,the globally asymptotical stability of periodic solution of system is obtained.
