Abstract Soil fauna are important biological factors that affect litter decomposition and play an important role in the release of nutrients, such as carbon and nitrogen. This study focused on the role of soil fauna in litter decomposition. Field microcosm experiments were conducted to assess the influence of isopods (Porcellionidae and Armadillidiidae) on soil nutrients during the litter decomposition of Catalpa bungei (CL), Platanus acerifolia (PL), and Aesculus chinensis (AL). The litter mass loss and nutrients in different soil layers treated with various isopods were determined in three-month microcosm incubations. Results showed that the presence of isopods significantly increased (P

陆生等足动物对凋落物分解过程中土壤养分的影响

摘要 土壤动物群是影响凋落物分解的重要生物因子，在碳、氮等养分的释放中起重要作用。本研究侧重于土壤动物在凋落物分解中的作用。进行田间微观实验以评估等足类动物（Porcellionidae 和 Armadillidiidae）在楸树 (CL)、梧桐 (PL) 和七叶树 (AL) 凋落物分解过程中对土壤养分的影响。在三个月的微观孵化中确定了用各种等足类动物处理的不同土壤层的凋落物质量损失和养分。结果表明等足类动物的存在显着增加（P
