凋落物氮磷释放动态受土壤动物和环境条件的影响。本研究的目的是探讨土壤动物对三种类型生态系统（即，山地森林、生态交错带和干旱河谷）。2013年11月至2014年10月，使用两种不同网目尺寸（0.04和3 mm）的垃圾袋进行了田间试验。研究了长江上游山地森林中冷杉（Abies faxoniana）和白桦（Betula albosinensis）、过渡带中栎（Quercus baronii）和柏木（Cupressus chengiana）以及干旱河谷中柏木和三叶草（Campylotropis macrocarpa）凋落叶分解过程中氮、磷的释放速率。土壤动物对不同分解时期和不同生态系统类型的N、P释放有显著影响。全年土壤动物介导的N平均释放率在干旱河谷（15.6-37.3%）高于山地森林（0.5-6.4%）和生态交错带（-3.7-4.9%）。土壤动物对磷释放速率的影响在山地森林和干旱河谷都表现出来。此外，土壤动物的影响在不同的分解阶段可能有很大的不同。结果表明，土壤动物对凋落物分解过程中N、P释放有显著影响。由动物介导的氮释放速率可能对植物物种的影响更敏感（即，而土壤动物介导的磷释放速率可能受到局部环境因子的影响（例如，温度，在更大程度上。
The dynamics of litter nitrogen (N) and phosphorus (P) release could be affected by soil fauna and environmental conditions. The objective of the present study was to investigate the effects of soil fauna on the dynamics of N and P during foliar litter decomposition in three types of ecosystems (i.e., montane forest, ecotone, and dry valley) along an elevation gradient. A field experiment using litterbags with two different mesh sizes (0.04 and 3 mm) was conducted from November 2013 to October 2014. Nitrogen and P release rates in decomposing foliar litter from fir (Abies faxoniana) and birch (Betula albosinensis) in montane forest, oak (Quercus baronii) and cypress (Cupressus chengiana) in ecotone, and cypress and clovershrub (Campylotropis macrocarpa) in dry valley were investigated in the upper reaches of the Yangtze River. Soil fauna strongly affected N and P release across different decomposition periods and ecosystem types. The average release rate of N mediated by soil fauna across the entire year was higher in the dry valley (15.6–37.3%) than in the montane forest (0.5–6.4%) and the ecotone (− 3.7–4.9%). The effects of soil fauna on P release rate were manifest in both the montane forest and the dry valley. Moreover, the impacts of soil fauna can vary substantially among different decomposition periods. Our results indicated that soil fauna can significantly affect N and P release during litter decomposition. The N release rate mediated by fauna was likely to be more sensitive to the effects of plant species (i.e., initial litter chemical traits), while the P release rate mediated by soil fauna might be subject to the effects of local-scale environmental factors (e.g., temperature) to a greater extent .
