摘要
以林分公顷株数和林分断面积作状态变量 ,采用林分价值生长量最大作最优指标函数 ,利用动态规划方法求算出湿地松材脂两用林最适经营密度 。
By using the stand density and the stand basal areas per hectare as the state variables,and by taking the maximum stand value increment as the optimal index function,the optimal stand management density of Pinus elliottii forest for timber and resin production was worked out by means of dynamic programming.And its corresponding equation was established.
