大木材是林地河流的重要物理成分，对河流形态有重要影响。它也是河流生态系统的关键组成部分。然而，大木材也是人类活动的风险来源，因为它可能会破坏基础设施，堵塞河道，并引发洪水。因此，大型木材及其流动性的分析和量化对于了解和管理河流中的木材是至关重要的。随着研究人员、河流管理者和利益相关者进行的大量与木材有关的研究的增加，记录常用和新可用的技术及其有效性也变得越来越重要。通过应用非常不同的方法获得了重要的数据和知识，并产生了代表不同环境的大量有价值的信息。本文从定性和定量两个方面对河流系统中大型木材动力学研究的最新进展进行了全面的定性和定量的总结，包括木材预算和木材力学。首先，介绍了一些关键的定义和概念。其次，回顾了在量化大型木材动态方面的进展；特别是，如何将测量和建模结合起来，以整合我们对大型木材如何在河流系统中移动和保留的理解。在整个过程中，我们提出了一个定量和综合的荟萃分析汇编从不同的研究和地理区域。最后，我们强调了具有特殊研究重要性的领域及其未来可能的发展轨迹，并考虑了一个特别未被研究的领域，以强调大型木材研究的未来挑战。
Large wood is an important physical component of woodland rivers and significantly influences river morphology. It is also a key component of stream ecosystems. However, large wood is also a source of risk for human activities as it may damage infrastructure, block river channels, and induce flooding. Therefore, the analysis and quantification of large wood and its mobility are crucial for understanding and managing wood in rivers. As the amount of large‐wood‐related studies by researchers, river managers, and stakeholders increases, documentation of commonly used and newly available techniques and their effectiveness has also become increasingly relevant as well. Important data and knowledge have been obtained from the application of very different approaches and have generated a significant body of valuable information representative of different environments. This review brings a comprehensive qualitative and quantitative summary of recent advances regarding the different processes involved in large wood dynamics in fluvial systems including wood budgeting and wood mechanics. First, some key definitions and concepts are introduced. Second, advances in quantifying large wood dynamics are reviewed; in particular, how measurements and modeling can be combined to integrate our understanding of how large wood moves through and is retained within river systems. Throughout, we present a quantitative and integrated meta‐analysis compiled from different studies and geographical regions. Finally, we conclude by highlighting areas of particular research importance and their likely future trajectories, and we consider a particularly underresearched area so as to stress the future challenges for large wood research.
