摘要:
 森林中的粗木质残体（CWD）不仅是生态系统重要的碳和养分储存库，同时也在森林更新、养分循环以及维持生物多样性等方面起到重要的作用。其结构性质随着环境和时间的变化而发生改变，有诸多因素影响其分解过程。为此，概述CWD的概念，将影响其分解的因子分为三大部分，探讨环境变化、分解者以及木材特性对CWD分解的影响以及作用机制。结果表明，在全球尺度上，气候因子是影响分解的主要原因，而局域尺度上则取决于分解者群落和木材特性。土壤动物通常在分解早期通过破碎CWD来促进分解，而微生物群落则在CWD分解的全过程中产生积极（或消极）影响。此外，木质素、萜类、酚类等化合物含量越高的木材分解越缓慢。最后对未来研究进行展望，以期在全球气候变化的环境下，能够完善全球碳循环模型并为生态环境保护提供理论依据。
Abstract:
 Coarse woody debris (CWD) in forests is not only an important store of carbon and nutrients for ecosystems but also plays an essential role in forest regeneration,nutrient cycling,and maintenance of biodiversity.The structural properties of CWD change with the environment and time,and many factors influence its decomposition process.In this review,the concept of CWD was introduced.Factors that influence the decomposition of CWD were divided into three parts.The effects of environmental changes,decomposers,and wood traits on CWD decomposition and the mechanisms of action were discussed.It was thought that climatic factors mainly affected CWD decomposition on a large scale,while at the local scale,CWD decomposition depended on the decomposer community and wood traits.Soil animals promoted decomposition by breaking CWD in the early stages of decomposition,and microbial community positively (or negatively) influenced throughout the CWD decomposition process.In addition,the higher the content of wood compounds such as lignin,terpenoid,and phenol,the slower the CWD decomposed.Finally,we provided an outlook for future research to improve the global carbon cycle model and provide a theoretical basis for ecological protection in global climate change.
