摘要： 土壤微食物网是碎屑食物网中与土壤生态过程密切相关的一部分,通过取食资源基质直接或间接地参与养分循环过程,影响陆地生态系统功能.本文从土壤微食物网的组成、结构和生态功能等方面综述了近年来土壤微食物网的研究进展.通过对土壤微食物网的能量通道及营养级联效应的介绍,阐述了土壤微食物网在碳(C)、氮(N)转化、凋落物分解和植物生长等方面的重要作用.针对目前的研究现状,提出未来土壤生态学研究应与高通量测序及稳定同位素技术相结合;通过构建模型进一步加强对土壤食物网结构和功能的研究,从而深入揭示地下生态过程及其对地上植物生长的反馈作用机理.

Abstract: Soil micro-food web, as a part of the detritus food webs, directly or indirectly participates in nutrient cycling by feeding on substrate and microorganisms and consequently influences the functions of terrestrial ecosystems. Here, we reviewed the research progress of soil micro-food web in recent years by focusing on its composition, structure and ecological function in soil ecosystem. The important roles of soil micro-food web in driving carbon (C) and nitrogen (N) transformation, organic matter decomposition and plant growth were reviewed through the description of energy channel and trophic cascade effects of soil micro-food web. At last, the research perspectives were put forward. Future researches should be combined with high-throughput sequencing and stable isotope techniques for better understanding the belowground ecological process and their feedback mechanisms to plant growth through modeling analysis.
