摘要
阐述了旱地土壤无机碳的形成机理,分析了干旱和半干旱土壤无机碳含量与土壤有机碳含量的关系,以及气候变化和人为土壤管理对旱地土壤无机碳储量的影响。旱地土壤可能通过形成次生碳酸盐转化为有效碳汇,说明了深入研究干旱土壤碳循环的重要性。
This paper expounded the formation mechanism of inorganic carbon in dryland soils,analyzed the relationship between inorganic carbon content and soil organic carbon content in arid and semi-arid soils,and the impact of climate change and artificial soil management on the storage of inorganic carbon in dryland soils.The dryland soil may be transformed into effective carbon sink through the formation of secondary carbonates,which showed the importance of in-depth study on the carbon cycle of dryland soil.
