英文摘要Vegetation restoration has played a significant role in preventing soil erosion and enhancing soil carbon sequestration in the hilly regions of subtropical China. However, under long-term vegetation restoration, it remains unclear how soil organic carbon and nitrogen components synergistically change and whether their dynamics are consistent across different soil depths. This study investigates the soils of four major vegetation types in subtropical hilly regions: enclosed Masson pine forest (EMP), Masson pine forest (MP), slash pine forest (SP), and mixed broadleaf-conifer forest (MBC). Soil organic carbon (SOC) components, nitrogen components, and physicochemical properties were analyzed across different soil depths (0-100 cm) under these vegetation restoration types. Results showed that forest type significantly influenced SOC stability. The MBC exhibited the highest mineral-associated organic carbon (MAOC) content, indicating the highest SOC stability. Both the MBC and SP forests sequestered more iron-aluminum-bound organic carbon (FeOC) and less Ca-associated organic carbon (CaOC) compared to the other forest types. The dominance of FeOC over CaOC in these acidic soils highlights the critical role of iron-aluminum oxides in SOCSOC stabilization. Vegetation restoration significantly influenced the relationship between SOC and nitrogen components in the topsoil (0-20 cm), but this effect diminished in the subsoil (>20 cm). This study confirmed the depth-dependent impacts of long-term vegetation restoration on soil carbon stability and C/N stoichiometry in subtropical plantations. Targeted vegetation restoration strategies can improve SOC stability in subtropical plantations.
