降雨是森林用水的主要来源。降雨量的大小及其分布是重要的，因为它们影响森林的水平衡，土壤侵蚀，并可能，地球化学循环。然而，我们对穿透雨水滴大小分布的了解不足，阻碍了在识别穿透雨输入和森林的生物地球化学和生理生态之间的直接和间接联系方面的进展。这篇评论提供了一个快照，我们目前的理解穿透雨滴粒径分布通过跟踪穿透雨滴粒径研究的历史发展，并检查穿透雨滴粒径的决定因素。本文还回顾了雨滴粒径研究的理论和方法，以巩固我们迄今为止对穿透雨雨滴粒径分布的集体认识。我们目前知识中的一些差距包括：（1）融雪对穿透雨滴大小的影响;（2）不同冠层物候期影响穿透雨滴大小的作用和程度;（3）穿透雨滴大小影响森林土壤化学和生物地球化学循环的程度。填补这些知识空白可能会导致降雨分配过程的更好概念化，以及穿透雨和土壤侵蚀，森林生态化学和植物生理生态学之间的因果关系之间的更明确的联系。WIREs Water 2017，4：e1225. doi：10.1002/wat2.1225
Throughfall is the dominant input of water to forests. Throughfall drop size and the distribution thereof are important because of their influence on the forest water balance, soil erosion, and, possibly, biogeochemical cycling. However, our inadequate understanding of throughfall drop size distributions has hampered progress in the identification of direct and indirect linkages between throughfall inputs and the biogeochemistry and physiological ecology of forests. This review provides a snapshot of our current understanding of throughfall drop size distributions by tracing the historical development of throughfall drop size studies and examining the determinants of throughfall drop size. The theory and methods of drop size studies also are reviewed to consolidate our collective knowledge of throughfall drop size distributions to date. Some of the gaps in our current knowledge, among many, include: (1) the effects of snowmelt on throughfall drop size; (2) the role and extent to which different canopy phenophases affect throughfall drop size; and (3) the extent to which throughfall drop size affects the chemistry of and biogeochemical cycling within forest soils. Closing these knowledge gaps will likely lead to the better conceptualization of rainfall partitioning processes and more definitive linkages between the cause‐and‐effect relationships between throughfall and soil erosion, forest biogeochemistry, and plant physiological ecology, for example.
