Forest resources are one of the most important resources which men are survival of. We studied sustainable development tactics of regional forest resources . Volume model, describing the growing process of a tree, was built to establish the relationship between the age of grown up and the age of grow stagnation; also 1-D dynamic discrete model was established, considering the characteristic of number of trees in different ages in the condition that there is only a single kind of tree in the forest firstly; then multidimensional dynamic discrete model was formulated, providing the best felling policy that can meet lumber demand and have better age of stand structure. The simulation results show that the age of stand structure finally reach steadiness in one million hectares. Regional forest achieve sustainable development.
