【摘要】 以三都县森林资源二类调查为基础，用层次分析和线性规划法对三都县的林种、树种和林龄结构进行优化调整研究。结果表明，调整后的林种树种结构与调整前比较，更适合三都实际；按优化调整确定的采伐方案进行采伐，不仅能实现越采越多、越采越好的经营目标，而且使林龄结构趋于法正状态。使林业逐步走上可持续发展的道路。此外，还对森林结构优化调整中的一些问题进行讨论更多还原

【Abstract】 On the basis of the forest management investigation, to adjust the structure of the forest kinds, species and age in Sandu county by means of analytical hierarchy process,it shows that the forest kinds and species structure after adjustment is fitter for the reality in Sandu county than before regulation.
