摘要:

土壤有机碳是衡量土壤肥力的重要指标,对于促进土壤养分循环、增加养分有效性有重要作用。土壤团聚体是土壤的重要组成部分,是组成土壤结构的最小单元,受到自然因素和人为因素的影响,其形成转化过程与土壤固碳过程息息相关,因而研究团聚体和有机碳的关系及团聚体有机碳影响因素对于土壤结构的改善和土壤质量的提升具有重要意义。本文通过对文献的总结,明晰了土壤团聚体和有机碳的关系,阐述了土壤类型、施肥方式、土地利用和矿区复垦对土壤团聚体有机碳的影响,并从生物质炭的长期定位研究和复垦矿区的土壤修复两方面对土壤团聚体有机碳的研究进行展望,研究结果可为合理的农业生产提供科学依据。

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
