太子山几种阔叶树种测树因子相关性分析

Correlation Analysis of Tree Measurement Factors of Several Broad-Leaved Tree Species in Taizi Mountain

摘要:

本文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-Di for three species were linear, suitable models of H-D and Cw-D for three species were linears as well.
