Aboveground tree architecture is neither fully deterministic nor random. It is likely the result of mechanisms that balance static requirements and light-capturing efficiency. Here, we used terrestrial laser scanning data to investigate the relationship between tree architecture, here addressed using the box-dimension ( ), and the architectural benefit-to-cost ratio, the light availability, and the growth of trees. We detected a clear relationship between and the benefit-to-cost ratio for the tested three temperate forest tree species ( L., L., and L.). In addition, we could also show that is positively related to the growth performance of several tropical tree species. Finally, we observed a negative relationship between the strength of competition enforced on red oak ( L.) trees and their We therefore argue that is a meaningful and integrative measure that describes the structural complexity of the aboveground compartments of a plant as well as its relation to structural efficiency (benefit-to-cost ratio), productivity, and growing conditions (competition or availability of light).
地上树木结构既不是完全由确定性因素决定，也不是随机的。它可能是平衡静态需求和采光效率的机制的结果。在此，我们使用地面激光扫描数据来研究树木结构（这里用盒维数（ ）表示）与结构效益成本比、光照可用性以及树木生长之间的关系。我们检测到在所测试的三种温带森林树种（ 属、 属和 属）中，盒维数（ ）与效益成本比之间存在明显关系。此外，我们还能够表明盒维数（ ）与几种热带树种的生长性能呈正相关。最后，我们观察到施加在红橡树（ 属）上的竞争强度与其盒维数（ ）之间存在负相关关系。因此，我们认为盒维数（ ）是一种有意义的综合度量，它描述了植物地上部分的结构复杂性及其与结构效率（效益成本比）、生产力和生长条件（竞争或光照可用性）的关系。
