以不同酸度的模拟酸雨对褐土进行室内淋洗土柱试验。结果表明，Ｃａ２＋Ｍｇ２＋和Ｋ＋的１０年淋失总量与酸雨的Ｈ＋浓度呈显著的正相关关系，Ｎａ＋对酸雨的酸度不敏感。４种盐基离子淋失数量的顺序为Ｃａ２＋＞Ｍｇ２＋＞Ｎａ＋＞Ｋ＋，不同处理的酸雨对盐基危害的顺序为ｐＨ２＞ｐＨ３＞ｐＨ４及ｐＨ５。电导率受酸雨酸度的影响及不同淋洗年份间的变化与盐基离子有相同的趋势，又有自身和特点。
Cinnamon soil was leached with soil samples by simulated acid rain with different acidity. The results showed that there was a significant positive correlation between total leaching amount of Ca2 + Mg2 + and K + and H + concentration of acid rain. Na + was not sensitive to acid rain. The sequence of leaching amount of the four kinds of salt ions was Ca2 +> Mg2 +> Na +> K +. The order of the acid rain affected by different treatments was pH2> pH3> pH4 and pH5. Conductivity by the acid rain acidity and changes in different leaching years with the same trend of salt-based ions, but also has its own and characteristics.
