Abstract: Soil aggregates are the basic unit of soil structure. As an important part of soil, soil aggregates play an important role in the key ecological functions of soil (nutrient turnover, microbial activity and erosion resistance, etc.). This paper systematically summarizes the relationship between forest soil aggregates and the main ecological functions of soil. From the perspectives of physics, chemistry and biology, it sorts out vegetation (vegetation type, stand structure, plant fine roots, etc.), soil properties (porosity, bulk density, soil texture, iron and aluminum ions, etc.), soil microorganisms and other factors on soil aggregates, and put forward the deficiencies in existing research and possible future research trends. This has important theoretical and practical significance for in-depth understanding of the ecological function of forest soil aggregates and its impact mechanism, and for improving the ecological service function of forest soil aggregates.
