摘要
利用优势解析木资料,采用改进的 Chapman-Richards 模型,分别立地亚区拟合多形地位指数曲线。模型的拟合精度高,预测效果好,适用性强,可用于有林地立地质量评价。
In this paper,taking advantage of the data from the analyzed stems of dominant trees,adopting the improved Chapman-Richards model,each subzone's polymorphic site index curves are established respectively.It proves to be precise,suitable and good for forecasting.It can be used in site quality evaluation of forest land.
