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。
Taking the surface soils around Beisu coal mine and Baodian coal mine in Zoucheng city of Shandong province as an example, the distribution of heavy metal Cr in the surface soil of the coal mine area was studied by the combination of fixed-point sampling and indoor analysis. The results show that although the content of heavy metal Cr in different coal mines is different, the content of heavy metal Cr in the same coal mines shows a similar trend with the change of the distance from sampling points to the coal mines. That is, the content of heavy metals Cr increases with the increase of the sampling points Declining trend.
