| 中文摘要 |
| 酸性淋洗可导致土壤有机质含量的轻微下降,下降幅度与淋入液的酸度呈正比.除强酸性淋洗外,一般性的酸性淋溶对粘土矿物含量的影响不大.模拟实验的操作过程本身可使土壤性质发生一定程度的改变,分析实验结果时应对此因素加以消除. |
| 英文摘要 |
| This paper deals with variations of the contents of organic matter and clay particle in soil under influence of acidic precipitation. The results of simulated experiments showed that organic matter contents decreased in varying degree after acidic leaching, but acidity of leaching did-not have marked influence upon the clay contents. If the contents of metals in soil solution increased to critical coagulation, effifiency of el aviation would decrease. |
