我们认为树和冠的结构多样性可以而且应该被整合到整个植物的经济学谱中。生态学家发现，在进化过程中，某些功能性状组合比其他性状更可行，从而产生了一个性状权衡连续体，可以沿着几个变异轴进行总结，例如全球叶片经济谱和木材经济谱。然而，对于木本植物，树冠结构多样性也应该包括在最近引入的植物形态和功能全球谱中，目前只关注植物高度作为结构因素。最近在地面激光扫描（TLS）革命开启了以前所未有的细节定量描述树木三维结构的可能性。我们证明了基于TLS数据可以构建一个多维结构特征空间，该空间可以分解为几个描述性轴或谱。我们的结论是，基于全球木本植物的结构特征数据，现在是时候为木本植物开发一个结构经济谱了。我们提出了一些关于这个光谱上可能存在的结构特征的建议，以及这些特征如何帮助我们更好地理解树形-函数关系。</p>
<p>We argue that tree and crown structural diversity can and should be integrated in the whole-plant economics spectrum. Ecologists have found that certain functional trait combinations have been more viable than others during evolution, generating a trait trade-off continuum which can be summarized along a few axes of variation, such as the “worldwide leaf economics spectrum” and the “wood economics spectrum”. However, for woody plants the crown structural diversity should be included as well in the recently introduced “global spectrum of plant form and function”, which now merely focusses on plant height as structural factor. The recent revolution in terrestrial laser scanning (TLS) unlocks the possibility to describe the three dimensional structure of trees quantitatively with unprecedented detail. We demonstrate that based on TLS data, a multidimensional structural trait space can be constructed, which can be decomposed into a few descriptive axes or spectra. We conclude that the time has come to develop a “structural economics spectrum” for woody plants based on structural trait data across the globe. We make suggestions as to what structural features might lie on this spectrum and how these might help improve our understanding of tree form-function relationships.</p>
