The vertical distribution and stoichiometry characteristics of soil organic carbon (SOC), total nitrogen (TN), total phosphorus (TP) of soil profiles along an altitude gradient were investigated in Luofu Mountain, Guangdong. A total of ten sites at different altitude gradients in Luofu Mountain were selected and soil genetic horizon samples were collected. Soil physic-chemical properties, such as bulk density, soil particle-size composition, pH, SOC, TN, TP, total iron oxides (Fe t ), free iron oxides (Fe d ), amorphous iron oxides(Fe o ), CEC, etc, were
