Soil Al(Fe)-pools and basic properties of the forest soils gathered from five profiles (consisting of four horizons) in two catchments (SZY and LKS) in Hunan were determined. Al-and Fe-pools were higher in SZY than in LKS and generally higher in the top soils than in the subsoils. They, except Feox, were positively correlated to the content of soil organic matter in the two catchments. Acid deposition may affect transformation and leaching of soil Al and Fe through formation of soluble organo-metal complexes. Significant positive correlations were observed between various forms of Al and their corresponding forms of Fe in the soils. Moreover, acid deposition also increased leaching of toxic Al and possibly availability of nutrient Fe.
