森林生态系统中粗木质残体研究进展

Research Progress on Coarse Woody Debris in Forest Ecosystems

摘要:

粗木质残体通常是指森林生态系统中自然死亡或由于人为干扰形成的具有一定粗头直径的枯立木、倒地尚未分解和处于分解中的树干(倒木)、大枯枝和树桩，是森林生态系统重要的结构性和功能性单元，具有养分循环、碳库储存、群落更新以及为其他有机体提供生境等重要功能。本研究综述了国内外近年来关于粗木质残体在成因、分类、分布、生态功能等方面的研究进展，并对未来研究进行了展望，以期为粗木质残体研究提供参考。

Abstract:

Coarse woody debris usually refers to dead standing trees with a certain coarse head diameter, tree trunks(fallen trees),large dead branches and stumps that have not yet decomposed and are in decomposition formed by natural death or human disturbance in the forest ecosystem, which are important structural and functional units of the forest ecosystem, and have important functions such as nutrient cycling, carbon pool storage, community regeneration and providing habitat for other organisms. In this paper, we summarize the research progress on the genesis, classification, distribution and ecological function of coarse wood residues at home and abroad in recent years, and look forward to future research, in order to provide reference for the study of coarse wood debris.
