植物物质的分解是森林生态系统研究的重要组成部分，因为它在养分循环中起着至关重要的作用。不同树种的养分释放模式不同，这与凋落物数量性状和季节环境因子有关。凋落物的数量性状是分解的重要预测因子，分解速率随着森林生态系统中养分有效性的增加而增加。在生态系统水平上，凋落物数量性状通常与凋落物的物理和化学特性有关，例如，单位面积的叶片韧性和叶质量，以及木质素含量，单宁和总酚。因此，凋落物数量性状和分解的分析对于理解森林生态系统中的养分循环是非常重要的。通过研究凋落物数量性状在森林生态系统分解和养分循环中的作用，将为研究数量性状如何影响生态系统养分动态提供有价值的见解。这些知识将有助于今后的森林管理和养护做法。
Decomposition of plant material is an important component in the study of forest ecosystem because of its critical role in nutrient cycling. Different tree species has different nutrient release patterns, which are related to leaf litter quantitative traits and seasonal environmental factors. The quantitative traits of leaf litter are important predictors of decomposition and decomposition rates increase with greater nutrient availability in the forest ecosystems. At the ecosystem level, litter quantitative traits are most often related to the physical and chemical characteristics of the litter, for example, leaf toughness and leaf mass per unit area, and lignin content tannin and total phenolics. Thus, the analysis of litter quantitative traits and decomposition are highly important for the understanding of nutrient cycling in forest ecosystems. By studying the role of litter quantitative traits on decomposition and nutrient cycling in forest ecosystems will provide a valuable insight to how quantitative traits influence ecosystem nutrient dynamics. Such knowledge will contribute to future forest management and conservation practices.
