which are warming faster than the global average. Discriminating between particulate and mineral-associated organic carbon can constrain the uncertainty of projected changes in global soil organic carbon stocks. Yet carbon fractions are not considered when assessing the contribution of cold regions to land carbonclimate feedbacks. Here we synthesize field paired observations of particulate and mineral-associated organic carbon in the mineral layer。

We show that soil organic carbon in the first 30cm of mineral soil is dominated or co-dominated by particulate carbon in both permafrost and non-permafrost soils, positive land carbonclimate feedback.

with this vulnerability mediated by higher warming-induced losses of particulate carbon. The massive soil carbon accumulation in cold regions appears distributed predominantly in the more vulnerable particulate fraction rather than in the more persistent mineral-associated fraction, 附:英文原文 Title: Dominance of particulate organic carbon in top mineral soils in cold regions Author: Garca-Palacios,与较温和的生物群落相比,揭示了寒冷地区表层矿物土壤中颗粒有机碳的优势,土壤有机碳储量最大的地区是北极、亚北极和高山生物群落等寒冷地区。
