土壤结构是指土壤原生颗粒砂、粉土和粘粒排列成小块或团聚体的过程。现代定义承认土壤孔隙的重要性，将土壤结构称为固体和孔隙的大小，形状和排列，孔隙的连续性，保持和传输空气，水和溶解物质的能力，以及支持根系生长和发育的能力。土壤结构是土壤发育过程的物理表现。表层土壤结构也受到土壤管理的影响，包括添加有机质、耕作、动物和车辆交通。
Soil structure refers to the arrangement of the primary soil particles sand, silt and clay into peds or aggregates. A modern definition recognises the importance of soil pores by referring to soil structure as the size, shape and arrangement of solids and pores, the continuity of pores, their capacity to retain and transmit air, water and dissolved substances, and the ability to support vigorous root growth and development. Soil structure is a physical manifestation of the processes involved in soil development. Surface soil structure is also influenced by soil management through addition of organic matter, cultivation, and animal and vehicle traffic.
