Abstract:

Soil organic carbon is an important index to measure soil fertility and plays an important role in promoting soil nutrient cycling and increasing nutrient availability. Soil aggregate is the important component of the soil and the minimum unit of soil structure, influenced by natural factors and human factors, its formation process is closely related to soil carbon process, thus research the relationship between soil aggregate and organic carbon and aggregate organic carbon influencing factors for the improvement of soil structure and soil quality is of great significance. Based on the literature summary, we clarified the relationship between soil aggregate and organic carbon, elaborated the influence of soil type, fertilization method, land utilization and reclamation of mining area on soil aggregate organic carbon, and discussed soil aggregate organic carbon from the perspectives of long-term positioning research of the biomass carbon and soil reclamation of the mining area, the results could provide a scientific basis for agricultural production.

Key words: soil organic carbon, soil fertility, soil nutrient cycle, soil aggregate, fertilization, land utilization, reclamation, biochar, structure
