摘　　要：在研究重金属元素对德兴铜矿地区环境污染情况的过程中,采用了连续提取法对低品位矿石堆浸场等地的土壤样品进行测量,并以Cu元素存在形态作为指标,综合德兴铜矿地区的特点对Cu元素形态进行了深入的聚类分析研究,得出了Cu在当地土壤中主要以有机态和硅酸盐态存在,但是碳酸盐态等其他四种形态所含比例较大,并且在酸性或氧化环境下具有一定的迁移转化能力,对环境具有潜在危害的结论,为进一步研究其他重金属的迁移转化提供了参考,并为矿区的环境治理和复垦提供了有价值的科学依据.A-sequential extraction procedure is used to analyze the speciation of Cu of soil samples in a low-grade ore plot of the Dexing Copper Mine to study how heavy metals pollute the environment. Synthesizing the characteristics of Dexing Copper Mine to make clustering analysis deeply for speciation of Cu, draw a conclusion that shift and transformation of Cu in the local soil is steady relatively and exists mainly in organic matter and the residual fraction. But the carbonate fraction and others of Cu which contribute a lot in the total speciation could transfer under the condition of acidity or oxidation. Then Cu element would pollute the environment potentially. This article contributes much value to study transform of other heavy metal and the environment treatment and reclamation of diggings in science industry.
