增加土壤有机碳含量对维持土壤肥力和农业可持续发展,缓解温室气体增加和全球气候变化的影响具有重要意义.土壤团聚体是土壤的重要组成部分,影响着土壤的各种物理化学性质.土壤团聚体对土壤有机碳的物理保护是土壤碳固定的重要机制.本文综述了土壤团聚体对有机碳的固定作用,土壤团聚体固碳机制研究的经典方法和现代常规方法,并且针对研究中存在的问题探讨了今后的发展趋势. Increasing soil organic carbon content is of great significance to maintain the soil fertility and sustainable development of agriculture, and to mitigate the impact of increased greenhouse gases and global climate change.Soil aggregates are an important part of the soil and affect the physicochemical properties of the soil.Soils The physical protection of soil organic carbon by aggregates is an important mechanism of soil carbon fixation.In this paper, the classical methods and modern routine methods of immobilizing soil aggregates on organic carbon and carbon fixation of soil aggregates are reviewed, The issue of the future development trend.
