园林植物形态特征与叶面积指数关系研究

Research on Relationship between Morphological Characteristics And Leaf Area Index of Landscape Plants

摘要:

摘要：作者研究了武汉市18种园林植物的形态特征与叶面积指数（LAI）的相关性，结果表明：树木整形方式对LAI无显著影响,且LAI与树高（H）和冠高（H'）呈正相关关系（多枝闭心形除外），与胸（基）径（D）呈负相关关系，与冠幅（C）的相关性没有明显规律。在4种植物类型中（乔木、灌木、常绿植物和落叶植物），LAI与H和H'呈正相关关系（灌木除外），与D和C呈负相关关系（常绿植物与灌木除外）。乔木和落叶植物的LAI分别高于灌木和常绿植物。

Abstract:

Abstracts:The influence of morphological characteristics (including 4 types of trim, Hight(H), Crown width(C), Crown hight(H') and Diameter at breast (or Base) height of 18 garden plants) on leaf area index (LAI) was studied in Wuhan City. The results showed that type of trim had no significant influence on LAI，and LAI were positively related with H and H'(except in the situation that tree stem formed closed heart), negtivly related with D, not obviously related to C. Among 4 different types of plants (tree, shrub, evergreen plant and deciduous plant), LAI showed positive correlation with H and H'(except shrub), and D and C showed inverse correlation (except evergreen plant and shrub). LAI of tree and deciduous plant were respectively higher than that of shrub and evergreen plant.
