| 摘 要： | 本文根据题中给出的已知数据，对城区五个功能区的8种重金属元素（As、Cd、Cr、Cu、Hg、Ni、Pb、Zn）的浓度及分布范围，利用matlab软件中插值计算法和绘图功能，绘出了重金属元素在该城区的空间分布图．再运用变异系数值法初步估算出了每个功能区8种元素的变异系数值分析功能区重金属浓度超标情况，进而选用地累积指数法作优化模型，定量分析该城区内不同区域重金属的污染程度．根据采样的现有数据，分析了重金属在土壤中的传播特性，分析了重金属污染物在进入土壤环境系统后的迁移规律，阐述了土壤中重金属传播规律．

| Abstract: | Eight heavy metal elements(As、Cd、Cr、Cu、Hg、Ni、Pb、Zn)of five function areas are ploted in city by matlab,according to their concentration and distributing extension.Overproof concentration of eight heavy metal elements is estimated by using aberrance coefficient.Cumulate exponent of overground is choosed to optimize model.Polluting extent of eight heavy metal elements is analyzed in quantity.We expatiate diffuse character of eight heavy metal elements in soil and moving law,when heavy metal elements enter soil. |

| Keywords: | Heavy metal Interpolation Cumulate exponent of overground Circumstance system in soil Diffuse character Polyfit |
