摘要/Abstract

摘要： 土壤动物是驱动凋落物分解的重要生物因子, 在促进养分循环、维持土壤结构稳定及提高生态系统功能方面发挥着不可或缺的作用。然而, 由于土壤动物具有高多样性以及复杂的物种间相互作用, 其群落特征与凋落物分解速率的关系仍未被完全阐明。与此同时, 叶经济谱作为资源获取和利用策略的权衡, 可能直接或间接地影响土壤动物群落结构和功能。为探究不同土壤动物类群对凋落物分解的作用机制, 以及叶经济谱对土壤动物群落的潜在调控作用, 本研究在湖南八大公山亚热带森林选取了20种代表性植物的凋落物, 根据其核心功能性状构建了凋落叶经济谱; 并对其开展了为期13个月的分解实验, 利用3种不同孔径的网袋(0.07 mm、2 mm和5 mm), 探究土壤动物体型对凋落物分解的作用。结果表明: 共收集土壤动物28,786头, 隶属于11纲29目, 其中螨类和弹尾目为优势类群, 两者可占土壤动物总数的80%以上。凋落物种类显著影响了土壤动物密度和丰富度, 但对Shannon-Wiener多样性指数、Gini-Simpson指数和Pielou均匀度指数均无影响。凋落物性状形成的叶经济谱与土壤动物丰度和多样性均无相关性。土壤动物显著提高了凋落物分解速率, 其对分解的贡献可达45.28%。不同体型土壤动物对凋落物分解速率的贡献不同, 中型和小型土壤动物为28.31%。在所有体型动物均参与的情况下, 凋落物分解速率与土壤动物丰度和多样性均具有显著相关性。这些研究表明, 凋落物种类影响了土壤动物丰度; 土壤动物群落特征促进了凋落物分解和转化, 其类群不同程度地调节了凋落物的分解速率。本研究有助于深入理解土壤动物与凋落物分解之间的相互作用关系, 为森林生态系统养分循环、土壤生物多样性及森林生态系统管理和保护提供科学依据。

Abstract

Aims: Soil fauna are essential biological drivers of litter decomposition, playing an irreplaceable role in promoting nutrient cycling, maintaining soil structure stability, and enhancing ecosystem functions. However, due to the high diversity of soil fauna groups and their complex interspecific interactions, the relationship between their community characteristics and litter decomposition rates remains uncertain. Meanwhile, the leaf economics spectrum, which reflects the trade-off between resource acquisition and utilization strategies, may directly or indirectly affect the structure and functions of soil fauna communities. Here, we aim to explore the mechanisms by which different soil fauna groups affect litter decomposition and potential regulatory role of the leaf economics spectrum on soil fauna communities.

Methods: This study selected 20 representative plant litters from the subtropical Badagongshan region, Hunan, China. The leaf economics spectrum was constructed based on its core functional traits, and a 13-month litter decomposition experiment was conducted using mesh bags with three different mesh sizes (0.07 mm, 2 mm, and 5 mm) to investigate the effects of soil fauna body size on litter decomposition.

Results: The results showed that a total of 28,786 individuals were collected, belonging to 11 classes and 29 orders. Mites and Collembola were the dominant groups, accounting for over 80% of the total soil fauna. Litter species significantly affected soil fauna density and richness, but had no significant effects on the Shannon-Wiener diversity index, Gini-Simpson index, or Pielou evenness index. The leaf economics spectrum derived from litter traits was not correlated with soil fauna abundance or diversity. Soil fauna significantly increased the litter decomposition rates, contributing up to 45.28% of the total decomposition. Contributions varied across body size groups, with micro- and mesofauna accounting for 28.31% of the decomposition. When all body size groups of soil fauna were present, litter decomposition rates showed significant correlations with faunal abundance and diversity.

Conclusion: We demonstrated that litter species affect soil fauna abundance. The community characteristics of soil fauna promote litter decomposition and transformation. Different body size groups regulate decomposition rates to varying extents. This study contributes to a deeper understanding of the interaction between soil fauna and litter decomposition, and provides scientific evidence for forest ecosystem management aimed at enhancing nutrient cycling and conserving soil biodiversity.
