摘要
本研究以靖西铝土矿区土壤为研究对象,分析土壤中Cu、Zn、Mn金属元素的富集和迁移规律,旨在为矿区的生态建设和保护提供理论参考依据。研究结果表明,土壤中Cu、Zn、Mn金属在水平方向和垂直方向均呈现不同程度的迁移和富集,总体表现为矿区下游土壤金属含量大于上游方向,10~20 cm土层重金属含量最大,随着土层增加,重金属呈现减少趋势。
Taking Jingxi bauxite mining area as the research object,this study analyzed the enrichment and migration rules of Cu,Zn,and Mn metal elements in the soil,and aimed to provide a theoretical reference for ecological con struction and protection of the mining area.The results show that Cu,Zn,and Mn metals in the soil exhibit different degrees of migration and enrichment in the horizontal and vertical directions,the overall performance is that the soil metal content in the downstream of the mining area is greater than the upstream direction,and the heavy metal con tent in the soil layer of 10~20 cm is the largest.
