【摘要】 选取南方主要酸沉降区土壤作模拟酸雨淋溶实验，分析在酸雨作用下各土壤盐基离子的淋溶特性，硅、铝元素的释放规律及淋出液的ｐＨ 值变化特点。在此基础上，对土壤酸沉降的缓冲机制进行了探讨。更多还原

【Abstract】 By laboratory leaching experiments,the characteristics and mechanisms of cation release,Si and Al release and pH value of the leachate of some soil types collected from South China are analyzed,based on which the soil buffering mechanisms of acid precipitation are discussed.更多还原
