| 摘要: |
| 采用土壤中微量元素的连续浸提的分组方法,研究河北省20个表层土壤中 Cu 的形态分布。将土壤中 Cu 分为交换态、碳酸盐结合态、氧化物结合态、有机质结合态和残渣态,其平均含量分别为0.09 mg/kg,0.06 mg/kg,4.88 mg/kg,0.48 mg/kg,和9.20 mg/kg。并讨论了土壤中 Cu 的形态分布特征及影响因素。此结果有助于评价土壤中 Cu 的背景值和了解土壤中Cu 的化学行为。 |

| Abstract: |
| The fractionation method was used to study the form distribu- tion of Cu in 20 topsoils in Hebei Province.Total Cu in soil was fractionated into exchangeable,carbonate bound,oxide bound,organic matter bound and residual forms,and these average concentrations were 0.09mg/kg,0.06mg/kg, 4.88mg/kg,0.48mg/kg and 9.20mg/kg,respectively.Characteristics of the form distribution of soil Cu and factors affecting on it,were discussed.The results are helpful for evaluating the background of soil Cu and for understan- d... |
