本文根据动态规划基本原理,建立了按龄级分期进行森林收获调整的动态规划数学模型。并通过算例,介绍了模型的使用方法。将计算结果与线性规划进行比较,说明本方法是可行的,结论令人满意。本模型的主要特点是推算结果既是数值解,又是非数值解的动态关系式。这对处于动态变化中的森林资源收获调整是很有意义的。 According to the basic principle of dynamic programming, this paper establishes a dynamic programming mathematical model of forest harvest adjustment according to age-grade. And through an example, introduced the use of the model. Comparing the calculation results with the linear programming shows that this method is feasible and the conclusion is satisfying. The main characteristic of this model is that the result of the calculation is not only the numerical solution, but also the dynamic relation of non-numerical solution. This is of great significance to the dynamic adjustment of the harvest of forest resources.
