| 摘 要： | 为了解粉煤灰充填复垦土壤重金属污染情况，通过实地试验与现场采样化验相结合的方法，对复垦时间不同的粉煤灰复垦土壤里砷(As)、镉(Cd)、铬(Cr)、汞(Hg)、铅(Pb)、铜(Cu)、硒(Se)、锌(Zn)、、镍(Ni)和氟(F)等重金属和微量元素含量的时空变异性进行了研究。结果发现：以土壤本底值作为评价标准时，粉煤灰充填复垦土壤整体处于受污染状态。其中，表层复垦土壤受到Cd、Se、Zn、F 4种元素污染较重；粉煤灰充填复垦土壤适合旱作，不适合用作水田；随着复垦时间的增加，表层复垦土壤的污染指数呈递增趋势。

| Abstract: | Samples were taken from fly ash reclaimed soil to investigate the contamination of ten heavy metals, namely, Arsenic(As), Cadmium(Cd), Chromium(Cr), Hydrargyrum(Hg), Plumbum(Pb), Copper(Cu), Selenium(Se), Zincum(Zn), Nickel(Ni) and Fluorin(F). It was found that the soil reclaimed by fly ash was, as a whole, polluted according to common soil assessment standards. It was also discovered that, the surface reclaimed soil was severely polluted by Cd, Se, Zn and F elements, the reclaimed soil is suitable for dryland plant cultivations rather than wetland plant cultivations, and the contamination of heavy metals on surface soil was increased with cultivation time. |
