摘要
By soil sample collection, simulated acid rain experiment and sample analysis, the releasing characteristics and the transformation of aluminum in acid soils of south China are discussed in this paper. The results reveal that the leaching of acid rain induces release of aluminum from the soils. The amount of aluminum released from the soils increases with the decrease in pH value of the acid rain. Leaching of acid rain also causes transformation of aluminum forms in the soils. With the decreasing of pH value of the acid rain, The contents of hydroxy aluminum and organic aluminum decrease, whereas exchangeable aluminum in the soils increases.
