用动态淋洗试验，研究了不同pH的模拟酸雨对红壤中铝形态和性质的影响．结果表明，酸雨淋洗引起红壤中盐基离子的淋失和土壤铝的溶出．随着酸雨溶液pH的降低，盐基淋矢量和铝溶出量增加．酸雨淋洗影响土壤铝形态的转化，使红壤中交换态铝上升，吸附态羟基铝有所下降．这说明在酸雨长期作用下，羟基铝溶解，并转化为交换态铝和引起铝的溶出，使铝进入环境，危害生态系统．
With dynamic leaching test, the effects of simulated acid rain at different pH on the morphology and properties of aluminum in red soil were studied. The results showed that acid leaching caused the leaching of base-based ions in red soil and the dissolution of soil aluminum. As the pH of the acid rain solution decreased, the salt-base leaching vector and the aluminum leaching rate increased. The leaching of acid rain affected the transformation of soil aluminum forms, resulting in an increase of exchangeable aluminum in red soil and a decrease of the amount of adsorbed aluminum hydroxyaluminate. This shows that under the long-term action of acid rain, hydroxy aluminum dissolved, and transformed into exchangeable aluminum and lead to the dissolution of aluminum, the aluminum into the environment, endangering the ecosystem.
