摘要
为了给森林资源经营、管理提供指导,利用3块编号固定标准地调查资料,对常用的均匀分布、Meyer修正数据、累积分布曲线法等几种未来直径分布预估法进行了分析。结果表明,各种方法适应性都很强,其中以累积分布曲线法的精度最高,其精度是82.7%。
In order to provide guidance for management of forestry resources, analysis of prediction methods for stand future diameter distribution are conducted with the data from three sample plots. Results show that all the methods are effective in prediction, and , of them , the method of accumulated distribution curve resulted the highest precision of 82.7 %.
