| 摘 要： | 红壤中稀土元素的淋滤实验表明酸性红壤其稀土元素的淋出量比石灰性红壤高得多；淋滤液酸性越强，稀土淋出越强烈，添加粘土矿物及有机质后样品中稀土元素在酸性条件下淋出量比原样明显减少．

Research on Environmental Effect of REE in Red Soil under Leaching Conditions |

| Abstract: | Leaching experiments on REE in red soil show that REE contents leached in acidic red soil by leaching solutions are much higher than that in limestonic red soil. The more acidic leaching solutions are, the more the REE contents leached out .The leached contents of REE in red soil after adding clay mineral Weathering leaching Environmental effect |
