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22个点位采集粉尘样本,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。
本次研究以南京市為例,研究道路粉塵中的重金屬含量,併分析其空間分佈模式。在南京市依據用地類型的不同選取瞭22箇點位採集粉塵樣本,併對其中的Cr、Cu、Ni、Pb、Zn的含量進行檢測。結果錶明,道路粉塵重金屬在商業區用地上的含量最高的,在公園綠地區類型上的含量最少,而且粉塵中重金屬含量隨著樣點城市化時間變長而升高。

In this paper, Nanjing was taken as an example to study the content of heavy metals in the roaddust 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.
