| 摘 要： | 以三峡库区消落带的土壤-水体系统为研究对象,通过模拟实验研究重金属在土壤-水体系统中的迁移规律以及江水pH值的微小变化对重金属迁移行为的影响。实验结果表明:用被Pb、Cr、Cu和Zn污染后的江水浸泡土样,各层土样中Pb、Zn含量升高,Cr、Cu的含量则有不同程度的下降;在弱碱性范围内,模拟江水pH值的微小变化对重金属的迁移有不同程度的影响,各层土样中Pb、Cr、Cu的含量均随江水pH增大而升高,但对Zn的影响则随土层而异。

| Abstract: | A dynamic simulative experiment was undertaken to study migratory behavior of heavy metals such as Zn,Pb,Cu,and Cr between water and soil in the draw-down zone of Three Gorges Reservoir. Even the trivial changes of pH ranging from 7.60 to 7.83 were observed,as the impact on mobility of the heavy metals. |
