摘要
本文根据Seymour的以树冠投影面积和树高预测单木胸径的回归方程,分别对357株樟树(Cinnamomum Camphora)、378株楠木(PhoebeBounei)优势木和亚优势木样木数据进行拟合,进而导出树冠充分郁闭时,樟树高在7-17,楠木高在5-15M范围内林分断面积—每公项株数相对密度,并根据树冠竞争因子探讨林分密度管理。
A simple model that predict dbh of individual trees from cioun projection and total height was fitted to data 357 of Camphos(Cinnamomum Camphosa)and 378 of Nanmu (Phoebe bouei) trees fos dominant and codominant.These equaations were used to delcsminc height dependent stocking cusves of basal area and trees pes ha, at heights.of 7-17 M fos Camphos and 5-15m fos Nanmu trees when csown somplete closure .The above seslts psovidc an appsoach to the silvicultusal prlblems of density management based on the csown competi tion factos (CCF)
