| 摘 要： | 运用ArcGIS的地统计学组件，分析了金华市城市地表灰尘中重金属Ph、Cr、Cu、Zn、Ni、Mn的空间分布特征．结果表明：上述重金属具有复合污染或一定的同源性特征，其中Pb、Cr、Cu、Mn可能主要受金华市城市产业布局和功能分区等结构性因素的影响，而Zn则受非结构性因素影响更大，来源比较复杂．Ph、Cr、Cu、Zn、Ni等重金属的空间分布比较相似．

| Abstract: | Spatial variation characteristics of urban dust heavy metal including Pb,Cr,Cu,Zn,Ni and Mn in Jinhua were studied by the geostatistical component of ArcGIS(a kind of geographic information system tool).The results showed that Pb,Cr,Cu,Zn,Ni and Mn had combined pollution or a certain homologous regions charateristics,among them Pb,Cr,Cu and Mn were influenced by structural factors of urban industry layout and function division,while Zn was influenced by non-structural factors and had complication sources.Spatial variation characteristics of Pb,Cr,Cu,Ni and Zn were seemed to be similar. |
