Abstract: By the theory of periodic parabolic operators, Shauder estimates and bifurcation, the existence of positive periodic solutions for periodic prey-predator model with saturation is discussed. The necessary and sufficient conditions to coexistence of periodic system are obtained.

Key words: periodic , parabolic , operator;principal , eigenvalue;priori , estimates;bifurcation
