摘要
以山东省邹城市的北宿煤矿和鲍店煤矿周围表层土壤为对象,采用野外定点连续采样和室内分析相结合的方法,研究了煤矿区表层土壤中重金属Cr的分布规律。结果表明:不同煤矿区重金属Cr的含量虽然不同,但是同一煤矿区重金属Cr的含量随着采样点距煤矿区距离的变化呈现相似的变化趋势,即重金属Cr的含量随着采样点距离的增加而呈递减趋势。
As the surface distribution of heavy metal Cr in the soil was studied by a method of combining continuous sampling and laboratory analysis. The result showed that though the content of Cr distributes differently in different mines, the content of Cr in the same mine has a similar tendency with the change of the distance between sampling point and the coal mining area. That is to say, the content of Cr is reducing with the increasing distance of the sampling points.
