森林凋落物分解速率的影响因素研究进展
Research progress on the influencing factors of forest litter decomposition rate
摘要
Abstract
Litter is a crucial functional component in forest ecosystems.Its decomposition is not only a major pathway for material cycling and energy flow but also a key link in biogeochemical cycles.It profoundly impacts soil fertility,carbon storage and release,biodiversity,and other aspects,which plays a significant role in maintaining ecological balance.This paper systematically summarizes the main factors influencing litter decomposition,including quality features like chemical compositions and physical structures,etc.,of litter,changes in climate conditions,and the types and activities of soil decomposers,etc.Meanwhile,the paper thoroughly reviews recent research progress and hot topics in the field of litter decomposition both domestically and internationally.This has important theoretical and practical significance for enhancing forest ecosystem management,advancing material cycling research,and addressing global climate change.Future research should deepen understandings of topics such as home-field advantage,soil fauna roles,and photodegradation in various forest ecosystem contexts,and establish a systematic framework for studying decomposition mechanisms.Additionally,developing a long-term,fixed experimental network platform for different litter treatments(including addition and removal)against the backdrop of global climate change is crucial for revealing the mechanisms of litter decomposition on soil organic carbon transformation and stability.In the context of global climate change,this paper offers ecological insights and suggestions for further exploring the influencing factors and response mechanisms of litter decomposition processes.关键词
