摘要

利用pH2.50、3.50、4.50、5.60的模拟酸雨对三峡库区黄壤进行了室内土柱淋溶实验

研究表明:长时间受酸雨淋洗

黄壤对酸雨的缓冲性能降低

且酸雨pH值越低

对土壤酸化影响越大;不同酸雨淋溶不同层次土体的收集淋出液的电导都呈现先升后降的趋势

而且都有一个峰值

但峰形有明显差异;铝的淋失量随酸雨pH值下降而上升。

Abstract

Laboratory column leaching tests were conducted with simulated acid rain with pH values of 2.50

3.50

4.50 and 5.60 respectively

to study yellow soil taken from the Three Gorges Reservoir Region.The results showed that the buffer function of yellow soil against acid rain weakened after a long time of leaching

and acid rain of a lower pH exerted stronger impact on the acidification of the soil.The electric conductance (EC) of the leachates through different soil layers first increased

and then decreased.There is an EC peak occurred in the range of simulated acid rain addition

with the shape of the peak obviously different.The Al leaching loss of the soil increased when the acid rain was more acidic.
