摘　　要：土壤结构是土壤中各种过程进行的物理框架,土壤结构的定量化对土壤水、气、热和土壤生物、化学过程定量化研究具有重要意义。本文主要讨论了土壤结构研究的内容,介绍了土壤结构研究的主要方法,对分形理论、布尔模型和孔隙网络模型等在土壤结构中的应用作了简要的介绍,并且对未来土壤结构定量化研究进行了展望。Soil structure is the physical framework where all the soil processes occur. Quantification of soil structure is fundamental to the research on water movement, gas exchange, heat transfer, soil fauna activity, and soil chemical processes. Contents of the research were discussed, and major methods applicable to the study and applications of the fractal theory, Boolean model, and pore network model were briefly introduced. Besides, outlook of the study was presented.
