| 摘 要： | 以太子山常见的阔叶树种枫香树、麻栎及红果冬青为研究对象,采用SPSS分析胸径(D)与基部直径(Di)、树高(H)与胸径(D)、冠径(Cw)与胸径(D)等之间相关关系,结果表明:测树因子间存在极显著相关关系,各树种距离地面不同高处基径与胸径均呈线性相关,其中以D-D0.50模型拟合效果最好;树高与胸径、冠径与胸径也均为线性相关。

| Abstract: | Three common broad-leaved trees(Liquidambar formosana,Quercus acutissima and Ilex rubra)in Taizi Mountain were studied with SPSS software to establish correlations diameter breast-high(DBH)and basal diameter of stem(Di),height(H)and diameter breast-high(DBH),crown diameter(Cw)and diameter breast-high(DBH).The results showed that tree-measurement factors were significantly correlated.All suitable regression models of D-D0.50 for three species were best,suitable models of H-D and Cw-D for three species were linears as well. |
