摘要
森林的林层划分、树高—胸径模型是进行森林资源调查、调整林分结构等管理活动的基础。本研究基于汉寿县境内的樟树固定样地,分析其林分的林冠结构,构建树高—胸径曲线。结果表明:该林分无分层现象,垂直结构单一;而拟合结果表明一元线性和二项式模型拟合效果最好。通过分析汉寿县樟树公益林的垂直结构,提供了可靠的樟树林林层树高—胸径模型,为该地区森林经营提供科学支撑。
Canopy stratification and height-diameter model is the basis of forest management activities.In this research,the data from fixed sample plot of Cinnamomum camphora forest were selected in Hanshou County of Hunan Province,aim to analyze canopy stratification and height-diameter fitting curve.The results showed there is no stratification in the stand,and the one-dimensional linear regression and binomial model fitted best.The vertical structure of C.camphora forest in Hanshou County was described.This study provides a reliable height-diameter model for the C.camphora forest and the scientific support for forest management in this area.
