Land use changes profoundly affect the equilibrium of soil organic carbon (SOC) sequestration and greenhouse gas emissions. With current global climatic changes, it is vital to understand influence ecological restoration conservation management on dynamics SOC under different land uses, especially in erosion-endangered Loess soils. Therefore, we investigated through a suit labile fractions, namely: light fraction C (LFOC), heavy (HFOC), coarse particulate (CPOC), fine (FPOC), dissolved (DOC), from two forests i.e., Robinia pseudoacacia (RP) Platycladus orientalis (PO), with ages, comparison farmland (FL). The STN contents significantly increased over 42 years RP forest where CPOC FPOC were higher than FL. Moreover, total its studied types, correlated CaCO3, pH, contents, indicating their key roles sequestration. results reported here vegetation ages provide better understanding alterations at stages restoration. Our findings suggest that long-term natural could be an effective approach for soil.
