摘要
侧柏(Platycladus orientalis Franco,英文名为Oriental arborvitae)为喜暖旱中生乔木。侧柏林在群落分类上属于温性针叶林植被型、侧柏林群系组、侧柏林群系。侧柏是我国主要造林树种之一,广泛分布于全国各地,作为中心分布区之一的山东省。
Oriental arborvitae stand is the major community type in Mount Qianfo of Jinan. From mathematical analysis, it is found that major factors influencing its growth are stand density, soil water and soil depth. Their significance for four growth indices, i.e., height, dbh, basal diameter and standing stock are sequenced according to their values of standard regression coefficients. Optimal regression models of the four growth indices are founded using multiple step regression analysis. It quantitatively reveals the relationship between stand growth and environmental factors and provides theoretical and tcchnological guidance for the maintenance and development of forests.
