| Abstract: | This paper discusses the branching problems of the predater-pery systemwith thinning effect in the mathematical ecology, the total structure of the system in some parameters in probed. There exist at least 2or 3 limite cides in different parameter conditions, which is concluded by applying the Hopf branch theory and the borlering ring branch theory. |
