摘　　要：团聚体是土壤结构的基本单元,对土壤系统功能至关重要,其稳定性显著影响土壤结构与质量,深入研究团聚体的稳定性对更好地改良土壤结构和合理利用土地资源具有重要意义.比较分析了近年来土壤团聚体稳定性研究的主要方法,总结了团聚体稳定性不同表征和评价指标.通过梳理发现,尽管目前报道了大量团聚体稳定性的研究方法和评价指标,但是各种研究方法优劣参半,衍生出的评价指标尚未统一化、规范化,导致其结果往往可比性较差.由此提出了该领域今后研究方向:(1)加强土壤团聚体稳定评价研究;(2)探索土壤团聚体微结构研究新方法;(3)建立统一的土壤团聚体稳定性评价标准.Aggregate is the basic unit of soil structure,which is essential for the function of soil system.Its stability significantly affects the structure and quality of soil.Study of the stability of aggregates is of great significance for better improving soil structure and rational utilization of land resources.The main methods for soil aggregate stability research in recent years were compared and analyzed.Different kinds of characterization and evaluation for aggregate stability were summarized.Although a large number of research methods and evaluation indexes of soil aggregate stability have been reported,the advantages and disadvantages of various research methods are mixed,and the derived evaluation indicators have not been unified and standardized,resulting in poor comparability of their results.Therefore,future research directions in this field are proposed as follows:(1)strengthen research on the stability evaluation of soil aggregate;(2)explore new methods for the quantitative study of soil aggregates microstructure;(3)establish a unified evaluation standard for soil aggregate stability.
