土壤团聚体固碳的研究方法

Research methods of carbon sequestration by soil aggregates:A review

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.

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.
