| 摘 要： | 为调查研究北京市一些重点功能区的土壤重金属污染状况,在朝阳、海淀、石景山、通州、怀柔、顺义区等典型的耕地、林地、菜地、工业区、交通区、旅游区选择采集了10个土壤样本。对各样点土壤的pH值、有机质含量、速效P、速效K、全N、全P、全K以及重金属元素Cr、Cd、Pb、Zn的含量进行了测定。采用单项污染指数法和内梅罗综合污染指数法来评价土壤重金属污染程度,并针对北京市不同功能区的土壤重金属污染状况,提出了相应的防治措施与对策。

| Abstract: | To investigate the soil heavy metal pollution status in several important function zones in Beijing,10 soil samples were collected from the typical plantation,woodland,kailyard,industrial park,traffic spot and scenic spot of Chaoyang,Haidian,Shijingshan,Tongzhou,Huairou and Shunyi districts,etc.in Beijing.Analysis of physico-chemical properties including pH,soil organic matter were conducted.The heavy metals(Cr,Cd,Pb,Zn) in soil samples were determined by atomic adsorption spectrophotometry.By adopting the Single Factor Index and Nemerow Multi-Factor Index Methods,the pollution indices were calculated to assess the pollution extent.After the analysis and comparison of heavy metal pollution status among the several different function zones,the prevention countermeasures of soil heavy metal pollution were introduced. |
