| Abstract: | To increase soil organic carbon content is critical for maintaining soil fertility and agricultural sustainable development and for mitigating increased greenhouse gases and the effects of global climate change.Soil aggregates are the main components of soil,and have significant effects on soil physical and chemical properties.The physical protection of soil organic carbon by soil aggregates is the important mechanism of soil carbon sequestration.This paper reviewed the organic carbon sequestration by soil aggregates,and introduced the classic and current methods in studying the mechanisms of carbon sequestration by soil aggregates.The main problems and further research trends in this study field were also discussed. |
