| 摘要: |
| 本文综述了中国北方主要河流沉积物中重金属(Cu、Cr、Pb、Cd、Zn)的污染现状，对重金属污染来源进行分析，同时结合中国北方河流沉积物重金属污染状况，提出了治理对策，并着重分析受污河流沉积物修复技术，对不同修复技术的优缺点进行分析比较。通过对以往研究成果分析发现，中国北方主要河流沉积物中重金属Pb污染最为严重，Pb污染很大程度上与北方传统的燃煤习惯有关。而北方主要河流（辽河、淮河、黄河、松花江、海河）干流中，海河的重金属富集程度最高，除Cr外，其他元素均不同程度的超过页岩平均背景值。北方河流沉积物重金属污染修复必须依据受污河流的具体情况选取适宜的修复技术，才可能有效治理污染。 |

| Abstract: |
| The status of heavy metals (Cu、Cr、Pb、Cd、Zn) in the sediments of the main river in north china are described in this study. The authors analyzed the sources of heavy metals and presented the control measures of heavy metal pollution based on the advantages and disadvantages with the actual situation in the north of China. The results showed that the most serious pollution of heavy metals in the surface sediments is Pb that because of the northern traditional habits of coal. And Haihe River has the highest level enrichment of heavy metals among the main rivers (Liaohe River, Huaihe River, Yellow River, Songhua River, Haihe River) in the north China, and the other elements are exceed the average background value of the shale excepted Cr. The remediation measures must regarded two aspects that effects and costs, we should selected the most appropriate one according to the actual circumstances of the polluted rive. |
