森林粗木质残体分解因素的研究进展
A Review Decomposition Factors of Forest Coarse Woody Debris
摘要
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 in-fluence its decomposition process.In this review,the concept of CWD was introduced.Factors that influ-ence the decomposition of CWD were divided into three parts.The effects of environmental changes,de-composers,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 de-composition 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 pro-vided an outlook for future research to improve the global carbon cycle model and provide a theoretical ba-sis for ecological protection in global climate change.关键词
