以贵阳市区为研究地点,采集贵阳城区工业区、交通区、商业区、居民区、文教区、公园6个类别共89个采样点的表层土壤,分析土壤重金属在不同区域的分布特征,并分析其可能来源。最后对重金属污染状况进行总体评价。结果表明:重金属在土壤中已有一定程度的积累,在工业区、商业区、居民区的积累程度比较高。As的污染较为严重,达警戒水平,Cu、Ni、Zn在居民区的污染比较严重,均达警戒水平,Cu、Ni、Zn在工业区的污染最为严重,达轻度污染以上。
以貴暘市區為研究地點,採集貴暘城區工業區、交通區、商業區、居民區、文教區、公園6箇類彆共89箇採樣點的錶層土壤,分析土壤重金屬在不同區域的分佈特徵,併分析其可能來源。最後對重金屬汙染狀況進行總體評價。結果錶明:重金屬在土壤中已有一定程度的積纍,在工業區、商業區、居民區的積纍程度比較高。As的汙染較為嚴重,達警戒水平,Cu、Ni、Zn在居民區的汙染比較嚴重,均達警戒水平,Cu、Ni、Zn在工業區的汙染最為嚴重,達輕度汙染以上。

This study focused on characterization of heavy metals in the soil of the city of Guiyang,89 surface soil samples were collected from 6 land-use types, such as traffic areas, industrial area, commercial area, residential area, education and historical relics, public area. Distribution characterization and possible sources of heavy metals of Hg, Cd, As, Pb, Cr, Cu, Ni and Zn were analysised, and The overall assessment of heavy metals pollution were analysied. The results indicated that the surface soil was contaminated by heavy metals, especially in industrial area, commercial area and residential area. The concentration of As was high and should be paid more attention, the concentration of Cu ,Ni and Zn in residential area was higher and should be paid more attention, however, the concentration of Cu,Ni and Zn in industrial area was highest and above light pollution.
