摘要
柳杉针叶量与柳杉树高、胸径、树冠高度、树冠直径的相关分析，都呈极显著关系，但柳杉针叶重量与柳杉树冠直径取对数后关系更为密切，关系式为ｌｇＷ＝－０．０１９６９＋２．４３８２ｌｇＤ，ｒ＝０．９５６９，并以此建立柳杉树冠级数表。
Analysis on correlation between leaf weight and height,D.B.H.,crownheight, crown diameter of Cryptomeria fortunei demonstrated significant difference.But after taking logarithm of leaf weight and crown diameter, the relationshipshowed closer,the formula was lgw =-0. 01969 + 2.4382lgD,r=0. 9569.The crowngrade table was established on this basis.
