摘要

微团聚体是土壤团粒结构的基本组成单元

较大团聚体具有更强的稳定性

其形成与稳定对于土壤有机碳的长期吸存起着决定性作用。目前关于微团聚体形成与稳定性的研究多专注于农业土壤

红壤侵蚀地植被恢复后土壤团聚体稳定性、有机碳分布及微生物群落特征研究也主要集中在大团聚体上

而土壤微团聚体的动态变化及其主要影响因素尚不明确

对于其内在机制更缺乏了解。通过总结土壤微团聚体的形成过程及稳定性

综述了凋落物、根系和菌根对土壤微团聚体形成与稳定的影响

阐述了土壤微团聚体内微生物群落、化学结合态有机碳及有机碳结构是土壤有机碳稳定的重要机制

并提出了未来微团聚体研究方向

以期揭示红壤侵蚀退化地森林恢复过程中微团聚体形成和稳定的生物化学机制

从而为深入阐明有机质—土壤团聚结构—微生物—化学耦合作用和森林土壤碳吸存机制提供参考。

Abstract

Microaggregates are the basic unit of soil aggregate structure and have stronger stability than large aggregates. Their formation and stability play a decisive role in the long-term sequestration of soil organic carbon. Current studies on the formation and stability of microaggregates mainly focus on agricultural soils. Studies on soil aggregate stability

organic carbon distribution and microbial community characteristics after vegetation restoration in red eroded soil are also mainly concentrated on macroaggregates. However

the dynamic changes and their main influencing factors of soil microaggregates remain unclear

and the internal mechanism is still lack of understanding. In this paper

the formation process and stability of soil microaggregates were summarized

and the effects of litter

roots and mycorrhizal on the formation and stability of soil microaggregates were reviewed. It was expounded that microbial community

chemical combined organic carbon and organic carbon structure in soil microaggregates were important mechanisms for soil organic carbon stability

and the research direction of microaggregates in the later stage was put forward

in order to reveal the biochemical mechanism of the formation and stability of microaggregate in the forest restoration process of red eroded soil

and to provide a reference for further clarifying the coupling effect of organic matter

soil aggregate structure microbe and chemistry

and the mechanism of forest soil carbon sequestration.
