土壤聚集是导致土壤结构形成和稳定的关键生态系统过程，土壤结构由土壤团聚体和由此产生的孔隙空间基质组成。因此，它以多种方式显着改变植物根系和微生物的环境；因此，土壤结构提供了菌根运作和进化的基本环境。毫不奇怪，土壤聚集对于根系生长以及各种土壤特征和生态系统过程速率（例如碳储存和抗侵蚀性）都很重要（例如Jastrow等人，1998年；Six等人，2006年）。土壤的聚集是一个复杂的过程，受到一系列非生物因素（例如质地）的调节，并由植物和多个生物群及其相互作用介导；尽管存在这种复杂性，但植物根及其菌根共生体始终被发现是驱动土壤聚集的关键力量（Six et al., 2004；Rillig & Mummey, 2006；Leifheit et al., 2014）。植物和菌根真菌物种对土壤聚集的贡献分别不同（Reid & Goss, 1981; Angers & Caron, 1998; Eviner & Chapin, 2002; Rillig et al., 2002;
Soil aggregation is a key ecosystem process resulting in the formation and stabilization of soil structure, consisting of soil aggregates and the resulting matrix of pore spaces. As such, it significantly alters the environment of plant roots and microbes in a multitude of ways; thus, soil structure provides the basic setting in which mycorrhizas operate and have evolved. Not surprisingly, soil aggregation is important for root growth and for a wide range of soil features and ecosystem process rates, such as carbon storage and resistance to erosion (eg Jastrow et al., 1998; Six et al., 2006). The aggregation of soil is a complex process, regulated by a range of abiotic factors (eg texture) and mediated by plants and multiple biota groups and their interactions; in spite of this complexity, plant roots and their mycorrhizal symbionts are consistently found to be a crucial force in driving soil aggregation (Six et al., 2004; Rillig & Mummey, 2006; Leifheit et al., 2014). Plant and mycorrhizal fungal species, respectively, differ in their contribution to soil aggregation (Reid & Goss, 1981; Angers & Caron, 1998; Eviner & Chapin, 2002; Rillig et al., 2002;
