| 摘 要： | 城市表层土壤环境的重金属污染问题是随着城市经济的快速发展和城市人口的不断增加而呈现的环境问题.分析了现代某城市表层土壤中的As、Cd等八种重金属在生活区、工业区、山区、主干道路区及公园绿地不同的区域的含量水平进行了分析,得出了不同区域重金属的污染程度,从而揭示了城市近表层土壤中重金属含量的空间分布特征. |
| 关 键 词： | 重金属污染 特征分布 污染评价 |
The Spatial Distribution Characteristics on Surface Soil Heavy Metal Pollution of a City |
|
| Abstract: | With the rapid economic development of the city and the increasing population,the problem about heavy metal pollution on surface soil environment has arisen.The authors analyze the content of eight heavy metal elements(As,Cd etc.) in surface soil of different zones,such as living quarters,industrial area,mountain area,trunk road area and public greenbelt,and then infer the heavy metal pollution levels in different zones.Thus the space distribution features of surface soil heavy metal is revealed. |
| Keywords: | heavy metal pollution spatial distribution characteristics pollution evaluation |
