摘要: 本文根据人工林密度效应规律,在改进唐守正研究员等提出的断面积生长模型的基础上,提出了一种新的断面积生长模型,并利用福建中心产区杉木标准地资料进行参数的拟合。模型的精度验证结果表明,改进后的断面积生长模型比原模型具有更高的精度。本文还提出了应用改进后的断面积生长模型分析间伐效应的方法。

Abstract: In this paper,according to the law of density effect of plantation.a new basal growth model was estab-lished based on improving the basal area growth model proposed by senior research fellow Tang shouzheng.Using the data collected from the sample plots of Chinese fir kernel growing area of Fuiian,the parameters of the new model were fitted.The precision test result of the model showed that the improved basal area model has higher precision than the former.It also inuvduced an approach to analyse tranrang effect by using the improved basal growth model.
