Abstract:: The different oxidizability of soil organic carbon influcences soil quality and carbon. The objective of this study was to determine the change in soil oxidizable organic carbon fractions (F₁, F₂, F₃, F₄) at different elevation gradients in riparian wetland of Three Gorges Reservoir Area. The results showed that oxidizable organic carbon fraction F₁ and F₁/TOC (total organic carbon) were the highest among the sample sites. Although readily oxidizable carbon and F₂, F₃, and F₄ in riparian zone were lower than those in the control upland, F₁ had no significant difference between the sites of 155～165 m and the control upland. In riparian zone, readily oxidizable carbon and F₁ were higher in the sites of 155～165 m than those in the other sites, whereas there was no significant difference for F₂, F₃, and F₄ among sites. Soil readily oxidizable carbon and oxidizable organic carbon fractions showed the significantly positive relationship with soil total organic carbon, whereas F₃ and F₄ showed the significant positive relationship with total nitrogen. Liability index followed the order: 155～165 m > 145～165 m > 165～175 m, indicating that the lability of carbon followed the same order in riparian zone of Three Gorges Reservoir Area.
