| 摘 要： | 研究了在重金属污染土壤上种植马尾松20 a后土壤重金属化学形态的变化,结果表明,马尾松林地土壤中交换态重金属组分和土壤溶液中重金属浓度均明显高于废弃农地.土壤重金属的剖面分布也表明,重金属在土壤中的迁移马尾松林地大于废弃农地,而迁移程度Cd >Zn > Cu > Pb.在重金属污染土壤上种植的马尾松可增加土壤重金属的迁移和流失潜力. |

| Abstract: | Study on profile distribution, chemical forms and solute concentrations of four heavy metals (Cd, Zn, Cu and Pb) in 20-year Pinus massoniana forest soil near a hardware factory showed that it had a lower pH value, and higher activities and available fractions of heavy metals. The profile distribution of the metals also indicated that mobility of the metals was greater in the forest soil than that in open land, and decreased in the order of Cd > Zn > Cu > Pb. The study suggests that changing land use from open land to P. massoniana forest could make soil acidification, elevate concentrations of dissolved heavy metals in the soil solution and increased mobility and the leaching risk of heavy metals. |
| Keywords: | land use change acidification soil heavy metals mobility leaching |
