Light availability at the forest floor affects many forest ecosystem processes, and is often quantified indirectly through easy‐to‐measure stand characteristics. We investigated how three such characteristics, basal area, canopy cover and canopy closure, were related to each other in structurally complex mixed forests. We also asked how well they can predict the light‐demand signature of the forest understorey (estimated as the mean Ellenberg indicator value for light [“EIVLIGHT”] and the proportion of “forest specialists” [“%FS”] within the plots). Furthermore, we asked whether accounting for the shade‐casting ability of individual canopy species could improve predictions of EIVLIGHT and %FS.

评估结构和成分的冠层特征，以预测半天然温带混交林中林下层的光需求特征
森林底层的光利用率影响许多森林生态系统过程，通常通过易于测量的林分特征间接量化。我们研究了在结构复杂的混交林中三种基本特征（基础面积，冠层覆盖和冠层闭合）如何相互关联。我们还询问了他们如何预测林下层的光需求特征（估计为光的平均Ellenberg指标值[“ EIV LIGHT ”]和样地内“森林专家”的比例[“％FS ”） ）。此外，我们询问考虑单个树冠树种的遮盖力是否可以改善对EIV LIGHT和％FS的预测。
