| 摘 要： | 本次研究以南京市为例,研究道路粉尘中的重金属含量,并分析其空间分布模式。在南京市依据用地类型的不同选取了个22点位采集粉尘样本,并对其中的Cr、Cu、Ni 、Pb、Zn的含量进行检测。结果表明道路粉尘重金属在商业区用地上的含量最高的,在公园绿地区类型上的含量最少,而且粉尘中重金属含量随着样点城市化时间变长而升高。

| Abstract: | In this paper, Nanjing was taken as an example to study the content of heavy metals in the road dust and analyze the spatial distribution pattern. In Nanjing, on the basis of land use difference, 22 points were selected for dust sample collection and the content of Cr, CU, Ni, Pb and Zn in the samples was detected accordingly. The results showed that the content of heavy metals in the samples from down town was the highest, while that in the samples from the parkland was the lowest, Moreover, it was found that the longer the sampling place was urbanized, the higher the content of heavy metals in the dust was. |
