摘要
树冠叶面积与树干材积的关系,反映着林木叶部光合产物的供应与干部材积生长需要之间的供需关系,表现为叶面积与林木生长指标、尤其是与材积的关系。对这些关系的分析研究,有助于了解林木材积形成过程及其与环境条件的协调程度。
The relationship between leaf area of crown(L. A. C.) and growth indices in a poplar plantation had been investigated from 1983 to 1986. The leaf area of crown and the volume increment raise with the increasing of water supply. The leaf area of crown is highly correlated with height(H), diameter(D), volume(V) and D^2H of the tree. The heighest correlation is presented between leaf area of crown and volume (D^2H). Some related problems were discussed in this paper.
