| 摘 要： | 研究了我国南方酸沉降区主要土壤类型在模拟酸雨影响下，土壤中铝离子释放及铝形态转化的特点。结果表明，酸雨淋洗造成土壤中铝离子释放，酸雨pH值越低，铝离子释放量越大；酸雨淋洗还造成土壤中铝形态发生变化，酸雨pH越低，土壤中羟基态铝和腐殖质铝含量愈低，交换态铝含量越高，土壤中铝对植物和生态系统的危害性也越大。

| Abstract: | 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. |
