摘　　要：坡耕地是分布在坡面上、地面平整度差的一类旱作耕地,因受地形影响,存在水肥流失、土壤流失等问题。水土流失不仅导致有机碳流失,还消耗了坡耕地土壤碳库。而传统的农耕方式欠缺水土保持措施,进一步加剧了土壤侵蚀与碳流失。采取相应的侵蚀治理措施,是降低土壤碳流失风险的重要途径。为了解析有机碳在坡耕地土壤中的周转过程并揭示治理技术对土壤碳流失的影响,综述了近年来国内外关于土壤有机碳流失及其治理技术的相关研究,揭示了物理、化学对碳流失的直接作用以及微生物的间接作用。分析了不同技术措施的碳阻控、碳补充效应,并对微生物作用下的土壤有机碳周转机制、不同有机碳组的分子结构、不同技术的固碳效应研究进行了展望。Slope farmland,characterized by its distribution on slopes with uneven terrain,is a type of dryland farmland.The topography of these areas leads to issues such as water and fertilizer runoff and soil erosion.Soil erosion not only causes the loss of organic carbon but also depletes the soil carbon pool of sloping farmland.Traditional farming practices that lack soil and water conservation measures further intensify soil erosion and carbon loss.Therefore,implementing effective erosion control measures is crucial for mitigating the risk of soil carbon loss.To better understand the turnover process of organic carbon in the soil of sloping farmland and to assess the impact of remediation techniques on soil carbon loss,this review examines recent domestic and international research on soil organic carbon loss and its remediation techniques.The article highlights the direct effects of physical and chemical factors on carbon loss and the indirect effects of microorganisms.It also analyzes the carbon blocking and replenishment effects of various technological measures and anticipates future research on the soil organic carbon turnover mechanism under microbial action,the molecular structure of different organic carbon groups,and the carbon sequestration potential of different technologies.
