摘要: 以土壤动物为主导的碎屑食物链是凋落物生物化学降解的主要途径,也是实现森林生态系统碳和养分循环的关键环节。现有的研究结果已经清晰认识到:①气候环境是决定生态系统土壤动物多样性及其对凋落物分解贡献的首要因素;②凋落物质量明显调控了特定气候带内土壤动物与凋落物分解的相互作用关系;③全球气候与环境变化正在改变土壤动物多样性与凋落物特征,导致土壤动物对凋落物分解的作用更不明确。同时,当前土壤动物分类方法相对滞后、凋落物分解袋法等研究方法存在明显缺陷。今后应在不断完善研究方法的基础上,重点关注气候变化情境下凋落物质量变化与土壤动物群落演替的生态关联性,使得土壤动物参与的物质循环、能量流动与信息传递等关键过程更加清晰。

Abstract: Detritus food chain dominated by soil fauna is the main way of litter biochemical degradation, which also plays a key role in carbon and nutrients cycling in forest ecosystems. Existing studies clearly showed that:①climate is the primary factor controlling soil fauna biodiversity and their contributions to litter decomposition; ②litter quality dominates the interactions between soil fauna and litter decomposition in specific climate zone; ③global climate and environmental changes have been altering soil fauna biodiversity and litter quality, which in turn, make the interactions between soil fauna and litter decomposition more complicated. Moreover, current classification system for soil fauna is relatively backward and there are inevitable flaws litter-bag and other methods. Following the improvement of research methods, additional detailed works should focus on the ecological relationships between litter quality and soil fauna community succession and their responses to ongoing climate changes in the future. This may advance our understanding of material cycling, energy flowing, information transferring and other key ecological processes associated with soil fauna.

Key words: detritus food chain, material cycling, climate change, soil fauna community, litter decomposition
