粗木质残体(CWD)是森林生态系统中重要的结构性与功能性单元。本文在对国内外CWD 研究历史进行简要回顾的基础上,对其生态功能及其分解过程进行了系统分析。指出了目前CWD 研究的热点及存在的问题,并建议加强对CWD生态服务功能的定量化研究,为其在维持生物多样性、生产力和其它生态过程方面的经营管理提供科学指导。参57。
Coarse woody debris (CWD) is an important structural and functional unit in forest ecosystems. Based on a brief review of the research history of CWD at home and abroad, this paper systematically analyzes its ecological function and its decomposition process. The current hot issues and existing problems of CWD research are pointed out. It is suggested to strengthen the quantitative study of CWD ecosystem services and provide scientific guidance for the management of biodiversity, productivity and other ecological processes.
