Abstract: A dynamic regional forest management model has been developed to ensure the sustainable forest practice in a regional forest. The model was composed of two models; 1) a forest planning model, 2) a dynamic growth model. The forest planning model makes a forest working plan, considering economical conditions as well as forest growth. In the model, a working kind by the forest age and working priority order based on the forest growth are allocated to the each compartment. According to the priority order, working compartments are then temporarily
selected with the working history of the compartment considered. Finally, real working compartments are determined under the given amount of forest investment. The dynamic grov.th and yield model enables the user to simulate and project the development process of stands under various working kinds, intensities and cycles. Under the planned working kinds and intensities, this model estimates the produced volume and predicts the stand growth to the next plan year. Using the developed model. an optimum working and investment level for the regional forest can be established. The model would be suitable for the regional forest planning and the decision-making in the forest subsidy or support policy
