摘　　要：土壤有机碳与土壤团聚体是评价土壤质量的重要指标,两者相互作用。土壤有机碳促进土壤团聚体的形成、土壤团聚体保护和固存土壤有机碳。回顾了近年来土壤有机碳与土壤团聚体的相关研究,分别梳理了土壤有机碳和土壤团聚体对土壤质量的意义以及影响因素,阐述了土壤有机碳与土壤团聚体间相互作用的机制。合理的施肥、耕作等农田管理措施能调控土壤微生物,改变土壤有机质物质的分解和有机碳固存及分解速率;同时影响土壤团聚体的结构和稳定性。土壤有机碳通过土壤有机和无机胶结作用、植物根系与菌丝作用以及有机物填充作用促进土壤团聚体的形成;反之,土壤团聚体通过将土壤有机碳进行包裹,减少土壤有机碳矿化,以实现对土壤有机碳的物理保护。综上,对未来提高土壤有机碳含量与增强土壤团聚体稳定性的研究重点进行了探讨,以期为提高土壤质量提供参考。Soil organic carbon and soil aggregates are important indexes for evaluating soil quality,and they interact with each other.Soil organic carbon promotes the formation of soil aggregates,and soil aggregates protect and sequester soil organic carbon.In this paper,the relevant studies on soil organic carbon and soil aggregates in recent years were reviewed,the significance and influencing factors of soil organic carbon and soil aggregates on soil quality were sorted out,and the interaction mechanism between soil organic carbon and soil aggregates was expounded.Reasonable fertilization,tillage and other farmland management measures could regulate soil microorganisms,change the decomposition of soil organic matter and the rate of organic carbon sequestration and decomposition.It also could affect the structure and stability of soil aggregates.Soil organic carbon promoted the formation of soil aggregates through soil organic and inorganic cementation,plant roots and mycelia and organic matter flling.On the contrary,soil aggregates could reduce soil organic carbon mineralization by wrapping soil organic carbon,so as to achieve physical protection of soil organic carbon.In summary,the research focus of increasing soil organic carbon content and enhancing soil aggregate stability in the future was discussed,in order to provide a reference for improving soil quality.
