| 摘 要： | 通过对浙江省东北部杭州至宁波地区两个红壤剖面的模拟酸雨淋溶实验研究表明，随着时间的延续，盐基离子的淋失浓度会在某一时期出现一个峰值。该峰值的出现与酸雨的ｐＨ值并不简单相关，Ａｌ＾３＋的淋失浓度只是在酸雨ｐＨ值＝２．５左右才显增高并在淋出液ｐＨ＝４．０时有一个阈值，经ｐＨ＝２．５－３．０模拟酸雨１０余年降水量的淋溶，红壤中淋出液的ｐＨ值下降不超过０．８。

| Abstract: | Two red soils from Hangzhou and Ningbo of the Northeastern Zhejiang Province, were leached by simulated acid rain in laboratory.The leaching concentration of cation ions reached a beak value which was affect by the pH of the acid rain.The concentration of Al 3+ in the leachate increased markedly when the pH value of acid rain was brought to 2.5 or below.When the leachate pH was about 4.0,there was a threshold concentration of Al 3+ . |

| Keywords: | acid rain red soil cation ions leaching |
