| 摘 要： | 研究了模拟酸雨淋溶过程中对南方主要土壤重金属Cu的缓冲及释放现象。结果表明，土壤的Cu释放量随淋溶模拟酸雨pH值的下降而增大，酸雨的pH值是影响土壤重金属离子释放和迁移的主要因素，当pH〈3．0时，Cu的释放量明显增加，并且增长迅速。此外，淋溶量也是影响土壤中Cu释放的重要因素。

| Abstract: | This paper studies the releasing and buffering of copper in a main soil of South China under simulated acid rain leaching. Results shows that release amount increases as pH of rain decreases, and pH of rain is the main factors influencing the releasing and buffering. Release amount increases significantly when pH is below 3. Besides, quantity of rain is also an important factor in the process. |
