| 摘 要： | 采用人工土柱淋溶试验方法，研究了模拟酸雨对短期污染和长期污染土柱中稀土元素迁移和形态分布的影响。结果表明，在酸雨淋溶下，长期污染土柱中的稀土元素较短期污染土柱更容易向下迁移；红壤表层中稀土元素的生物有效态增加；在短期污染土柱的表层，稀土元素有较高的生物可利用性；在长期污染土柱中，稀土元素的生物可利用性也增加。 |
| 关 键 词： | 模拟酸雨 稀土 土柱 迁移规律 形态变化 影响因素 |

| Abstract: | Effects of simulated acid rain on form of REEs were investigated in both short-and long-term pollution using soil columns. The results showed that the mobility of REEs in long-term pollution soil column were higher than those in short-term pollution soil column. The bioavailability fraction of REEs increased under acid rain leaching. REEs in surface of soil column with short-term pollution had great bioavailability, while the bioavailability of REEs in the soil column with long-term pollution increased under acid leaching. |
| Keywords: | REEs long-term pollution short-term pollution leaching |
