露天煤炭开采区土壤重金属污染评价与风险评估研究

Evaluation and Risk Assessment of Soil Heavy Metal Pollution in Open-pitCoal Mining Area

以A矿区为例,针对露天煤炭开采区土壤重金属污染进行治理。介绍了一种矿区土壤重金属污染评价与污染生态风险评估方法。采用地质累积指数法评价重金属污染的元素类型、污染程度和空间分布特征,并通过生态危险指数模型评估,提高了相关工作人员对矿区重金属污染情况的了解程度,为矿区生态环境的改善提供了支持,并确认了该方法具有一定的应用价值。

Taking A mining area as an example,soil heavy metal pollution in open-pit coal mining area was treated.A method of soil heavy metal pollution assessment and ecological pollution risk assessment in mining area was introduced.The geological accumulation index method was used to evaluate the element type,pollution degree and spatial distribution characteristics of heavy metal pollution,and the ecological risk index model was used to carry out the evaluation,so as to improve the understanding of relevant workers on the heavy metal pollution in the mining area,which provided support for the improvement of the ecological environment in the mining area,and confirmed that the method proposed in the study had certain application value.
