土壤团聚体具有复杂的空间异质性和营养异质性，对土壤微生物群落生态和土壤地球化学具有重要的调控作用。然而，长期施肥处理下，不同土壤颗粒级中氮循环微生物的分类组成和功能属性如何仍然是未知的。在这里，我们研究了附着在不同大小的土壤颗粒上的微生物群落的组成和脲酶活性、硝化作用、N2 O产生和还原的代谢潜力（2000-250，250-53和2000 - 250）。
Soil aggregates, with complex spatial and nutritional heterogeneity, are clearly important for regulating microbial community ecology and biogeochemistry in soils. However, how the taxonomic composition and functional attributes of N-cycling-microbes within different soil particle-size fractions under a long-term fertilization treatment remains largely unknown. Here, we examined the composition and metabolic potential for urease activity, nitrification, N2O production and reduction of the microbial communities attached to different sized soil particles (2000-250, 250-53 and
