土壤团聚体与有机碳固定关系研究进展

         

摘要

Carbon sequestration in soil is one of the path that nature sequestrates carbon .It is crucial in maintaining the productivity of soil as well as in stabilizing the global climate .Soil aggregates constitute an important part of the soil .It is an organo‐mineral complex that affects a wide variety of physical and chemical properties of the soil . Therefore ,soil aggregates and organic carbon are closely related .Abundant data and information on the related subject have been accumulated in recent years .With the advanced methodologies ,studies are aimed to understand the underlining mechanism of the carbon sequestration .This article reviews the available methods to retrieve organic carbon from soil aggregates ,the relationship between soil aggregates and organic carbon ,and the sequestration of organic carbon in aggregates .Prospect of future development on the research are discussed with an anticipation of an increased interest in this field of study in the near future .%土壤固碳是目前认可的固碳措施之一,对稳定土壤生产力和应对全球气候变化具有积极效应。土壤团聚体是土壤的重要组成部分,也是一种特殊的有机‐无机复合体,影响着土壤的各种物理和化学性质,因此土壤团聚体和有机碳是不可分割的,目前土壤团聚体中有机碳方面已经积累了大量的研究,随着现代研究方法的发展,已经深入到不同方式下的固碳机理研究。本研究通过大量阅读文献和查阅资料,在综合各方面研究的基础上,探讨了团聚体中有机碳的分离方法、团聚体与有机碳的关系、团聚体有机碳固定的途径和方法,并进行了相关展望,以期为团聚体中有机碳的研究提供理论和方法上的支持,促进农业和固碳减排技术可持续发展。
