森林凋落物分解影响因素的研究进展

Research Progress of Influencing Factors Affecting Forest Litter Decomposition

凋落物是森林生态系统中重要的环节之一,作为连接地上部分和地下部分的纽带,对森林的生态功能不言而喻。而凋落物的分解是森林的枯枝落叶分解的养分回归土壤、补充土壤养分的过程。研究凋落物的分解及其影响因素可以掌握促进凋落物的因子,从而快速释放养分,起到保肥作用。关于影响森林凋落物的影响因素已经展开一系列的研究,但是尚缺乏系统总结,该研究归纳总结国内外相关文献,综述了影响森林凋落物的因素,分别为大气氮沉降、气候变化、自然灾害、人类干扰等因子,分析目前研究的不足并提出展望,以期为有效利用森林凋落物、提高森林生态功能提供参考依据。今后除了在以上方面进行研究之外,可在各因素之间的交互作用对凋落物分解的影响等加强研究。

The litter is one of the important links in the forest ecosystem,and as a link connecting the ground and underground parts,it is self-evident for the ecological function of the forest.The decomposition of the litter is the process of the decomposed nutrients of the forest returning to the soil to supplement the sudden nutrients.Research on litter decomposition and its influencing factors can master the factors that promote litter,thus quickly release nutrients and play fertilizer preservation.A series of studies have been conducted on the influencing factors affecting the forest litter,but there is still a systematic summary.This study summarized the relevant literature at home and abroad,and summarized the influencing factors affecting the forest litter,which were atmospheric nitrogen depression Reduction,climate change,natural disasters,human interference and other factors,analyze the deficiencies of the current research and put forward prospects,in order to provide a research basis for the future effective use of forest litter,and improve the function of forest ecology.In addition to the above aspects,the influence of the interaction between various factors on the litter decomposition could be strengthened.
