| 摘 要： | 森林粗木质物残体（CWD）在保持森林生态系统的完整性方面发挥着重要的生态功能，影响着系统内外相关的生物和非生物过程，不仅为微生物、节肢动物、鸟类以及哺乳动物提供栖息环境，也是生态系统中重要的碳库和养分库，而且在减少土壤侵蚀和森林水文生态方面具重要的作用．文章总结了CWD的研究历史及状况，系统地阐述了CWD的形成和来源、贮量、分解、碳元素和营养元素的贮藏功能以及CWD对森林的更新作用、对生物多样性的维持和水文生态功能等．对今后CWD研究的重点及方向提出了建议．

| Abstract: | Woody debris(WD) including coarse woody debris(CWD) and fine woody debris(FWD),is an essential structural and functional component of many ecosystems.CWD plays critical ecological roles in maintaining the integrity of forest ecosystem and influences the biological and non-biological process within forest ecosystem.They not only provide habitats for organisms such as microorganism,amphibians,arthropods,birds,small mammals and so on,but also serve as carbon and nutrient pools.Furthermore,CWD can prevent from ... |
