文摘

The source of erosion-induced soil carbon was identified via 13C and C/N ratio. We assess relative contributions of soil carbon from different land use types. The young forest dominates the supply of surface sedimentary carbon. Soil water content and pH affects the distribution pattern of deposited SOC.
