| 中文摘要: |
| 采用苔藓植物大灰藓作为监测物种，考察Pb、Zn、Cu、Cd、Cr、Hg等6种重金属元素在大气中的分布情况，分析研究区域内各样点大灰藓和土壤中的6种重金属含量。结果表明，大灰藓中重金属含量依次为Zn>Pb>Cr>Cu>Cd>Hg，土壤中重金属含量依次为Zn>Pb>Cr>Cu>Hg>Cd。通过Kriging插值运算，得到6种重金属元素含量等值分布图，直观地体现了6种重金属元素的空间分布，说明大气重金属空间分布与区域产业类型及发展状况紧密相关。 |
| 英文摘要: |
| Hypnum plumaeforme， a type of moss， was chosen as the monitoring object for investigating the distribution of six kinds of heavy metals in the atmosphere by analyzing the content of these heavy metals in Hypnum plumaeforme and the soil at each sampling site in the study area. The results showed that the content of the heavy metals from high to low in order were Zn， Pb， Cr， Cu， Cd， Hg in Hypnum plumaeforme， and Zn， Pb， Cr， Cu， Hg， Cd in the soil. The contour map which expressed directly the spatial distribution of the heavy metals was obtained by Kriging interpolation operation. It indicated that the spatial distribution of heavy metals in the atmosphere was closely related to regional industry types and development status. |
