摘要
为了阐明森林凋落物分解各方面的研究,本文针对森林凋落物分解的研究进展进行了阐述,主要包含凋落物(落叶层)的概念和研究历史、凋落物的分解过程与养分释放、凋落物分解的影响因子以及其在主/客场生境中的研究情况,对森林资源的可持续利用具有重要意义。随着全球气候变化日益受到人们的关注,目前关于CO_(2)排放和N沉降影响凋落物分解的报道越来越多,但是要想更好地应对这些变化,综合性、可广泛使用的凋落物分析预测技术与指标却尚未建立。面对今后外部环境和学科的发展,还需要更多的学者提出全面有效的措施。本文在总结森林凋落物研究进展的基础上,旨在为该领域的进一步探索奠定基础。
In order to clarify the research on various aspects of forest litter decomposition, this paper summarized the research progress of forest litter decomposition, mainly including the concept and research history of leaf litter, the decomposition process and nutrient release of litter, the influencing factors of litter decomposition, and the research on forest litter in the’home’/’away’habitat. The study is of certain significance to the sustainable use of forest resources. As global climate change is increasingly concerned by people, there are more and more reports about the impact of CO_(2)emission and N deposition on litter decomposition, but to better deal with these changes, the comprehensive and widely used technologies and indicators of litter analysis and prediction have not yet been established. Facing the development of the external environment and disciplines in the future, more comprehensive and effective measures need to be proposed. Based on summarizing the research progress of forest litter, this study aims to build a basis for further exploration in this field.
