摘要: 土壤动物作为土壤生态系统的重要组成部分,是调控土壤碳循环的重要环节。然而,目前土壤动物对土壤碳循环的影响尚不明晰,且缺乏系统总结。基于此,本文结合近年国内外土壤动物相关研究,总结了土壤动物对枯落物分解过程、土壤碳碳库稳定性、植物和微生物调节、土壤呼吸的影响。提出未来研究从区域上应更加关注低纬度地区,研究手段上应强化野外实验与室内模拟实验的结合,研究内容上应加强相关机理研究、深化土壤动物呼吸及其对碳的净固存方面,研究方向上应结合全球热点问题,以期深入了解土壤动物对土壤碳循环的影响。

Abstract: As an important component of belowground ecosystem, soil fauna plays a vital role in regulating soil carbon cycling. However, previous studies provided limited scope for the effects of soil fauna on soil carbon cycling. Based on the analysis of recent literatures, we presented an integrated overview to summarize the effects of soil fauna on litter decomposition, soil carbon stock, the regulation of plants and microorganisms, and soil respiration. To better understand theimpacts of soil fauna on soil carbon cycling, future research should be strengthened in the following aspects: more attention to the lower-latitude areas; the combination of field experiment and lab simulation test should be strengthened as for the research methods; the mechanism such as soil fauna respiration and the effects of fauna on net carbon sequestration should be deepened regarding the research contents; and global hot issues should be combined regarding the research fields.
