| Abstract: | In this paper,the stationary model for the universally fatal diseases and insect-pest of age-structured evenage pure forest is considered,and the existenee and uniqueness of the solution of the model are proved under certain conditions. Finally,the steady-state distribution of the stationary model is calculated. |
