| 摘 要： | 采用变分法及最优控制理论就如何从空间和时间上合理安排与调控森林资源做了具体研究,得出了人工林的间伐强度和蓄积密度的最优控制策略及其连续变化的数学模型,其优点在于突破了以往仅给出离散状态下模型的局限性,从而为人工林的持续经营管理提供了理论依据。

| Abstract: | How to reasonably arrange and adjust forest resources in time and space was studied by the variation method and the optimal control theory. Optimal control tactics for thinning density and volume density of plantations and mathematical models with continuous variations were obtained. The limitation for given models only in scattered state in the past studies was broken through, which provides a theoretical basis for decision-making in sustainable management of planted forests. |
