| 摘 要： | 基于一般可更新资源动态的微分方程模型,在适当假设下,应用经济学原理推导出了一个偏微分方程,该方程能够进一步推导出变分法中著名的Euler方程,但它不等价于Euler方程。用修改的Richard模型研究林分蓄积动态,对来自小兴安岭原始红松林的实测数据进行了拟合,得到很满意的结果。在此基础上引用了本文所得到的偏微分方程求解林分最优经营问题,对最优经营策略控制林分蓄积动态的生物学意义和经济学意义进行了解释。

| Abstract: | A partial differential equation which follows some condition is derived according to economic principle. This equation can derive the famous Euler's equation farther and is not equivalent to Eulcr's equation. Richard's equation is used to study the dynamic of forest stand, by which a data set from Korean pine stand in Xiaoxing'anling Mountain is fitted. The fitted equation is satisfactory and substitutes in the partial differential equation obtained in this paper to research the optimal management policy. Finally, the biological and economic meaning of controlling the volume of forest stand is explained according to the optimal policy. |
