Trees can differ enormously in their crown architectural traits, such as the scaling relationships between tree height, crown width and stem diameter. Yet despite the importance of crown architecture in shaping the structure and function of terrestrial ecosystems, we lack a complete picture of what drives this incredible diversity in crown shapes. Using data from 374,888 globally distributed trees, we explore how climate, disturbance, competition, functional traits, and evolutionary history constrain the height and crown width scaling relationships of 1914 tree species. We find that variation in height-diameter scaling relationships is primarily controlled by water availability and light competition. Conversely, crown width is predominantly shaped by exposure to wind and fire, while also covarying with functional traits related to mechanical stability and photosynthesis. Additionally, we identify several plant lineages with highly distinctive stem and crown forms, such as the exceedingly slender dipterocarps of Southeast Asia, or the extremely wide crowns of legume trees in African savannas. Our study charts the global spectrum of tree crown architecture and pinpoints the processes that shape the 3D structure of woody ecosystems.
树木在树冠结构特征方面可能存在巨大差异，例如树高、树冠宽度和树干直径之间的比例关系。然而，尽管树冠结构对于塑造陆地生态系统的结构和功能至关重要，但我们仍缺乏对驱动树冠形状这种惊人多样性的因素的全面了解。利用来自全球374,888棵树木的数据，我们探究了气候、干扰、竞争、功能性状和进化历史如何限制1914种树木的高度和树冠宽度比例关系。我们发现，高度-直径比例关系的变化主要受水分供应和光照竞争控制。相反，树冠宽度主要受风灾和火灾影响，同时也与机械稳定性和光合作用相关的功能性状共同变化。此外，我们识别出了几个具有高度独特树干和树冠形态的植物谱系，比如东南亚极为细长的龙脑香科树木，或者非洲稀树草原上树冠极为宽阔的豆科树木。我们的研究描绘了全球树冠结构的图谱，并确定了塑造木本生态系统三维结构的过程。
