| 摘 要： | 为全面了解某城市表层土壤重金属污染的空间分布特征,对城市表层土壤中重金属元素As、Cd、Cr、Cu、Hg、Ni、Pb、Zn进行采样分析,采用域法识别特异值进行数据处理。通过Matlab软件,利用克里格法进行空间插值,绘出各重金属浓度与各坐标投影的一维空间分布图,并绘出全城等高地形图,再以数字大小标注样本点的污染浓度,拟合各元素浓度与海拔、平面坐标之间的关系模型,将重金属空间分布特征定量化、模型化。

| Abstract: | For full understanding the spatial distribution features of the heavy metal pollution in the city surface soil,this paper analyzed the heavy metal samples,including：As 、Cd 、Cr 、Cu 、Hg 、Ni 、Pb 、Zn,in surface soil and processed the data with domain identification method.It used Krieger method for spatial interpolation through Matlab software,draw a one-dimensional spatial distribution map of each heavy metal concentration and polar projection,and draw contour topography map of the whole city,then marked the contamination of the sample points with different numerical magnitude,simulated the relationship model of each element concentration,altitude and plane coordinate to quantize and modeling the spatial distribution features of the heavy metal. |
