同龄林理想森林结构的探讨

本文利用多目标数学规划法提出了新的森林结构理论,克服了法正林、广义法正林和完全调整林的片面性以及目标林的模糊性等缺陷。论述了如何确定经营单位内多个树种的整体森林结构。结合江山娇林场的具体情况模拟了红松、落叶松、柞树的整体结构并求解。这种森林结构具有动态性、整体性、效益最大性、多样性等特点,同时便于森林结构在山头地块的具体落实。

PROBING INTO OPTIMAL FOREST STRUCTURE OF EVENAGED STANDS

In the article, a new theory of forest structure, which eliminates the shortcomings of normal forest, generalized forest and regulated forest, has been proposed by using multi-objectiye mathematical programming, At the same time, it has been discussed how to determine the whole forest structure of a specific forestry farm which has several tree species to manage. Taking jiang shanjiao Forestry Farm as an example, the whole structure of korean pine, toothed oak and larch is modified and solved. This kind of forest structure has the characteristics of dynamity, entirety, benefits-maximum and inflexity. Meanwhile, it is very easy to be located on the forest land.
