为了解陕西省潼关县金矿周围土壤的污染状况，对矿区土壤污染进行人工生态修复治理，以矿区周围土壤为研究对象，采用快速测定法对土壤中Zr、Co、Se、Fe、Ti 5种重金属含量进行分析。结果表明：Zr、Ti、Fe 3种重金属在研究区内累积均较少，Co、Se累积严重；在样区1和样区3内，重金属分布较为均一；样区4和样区5内重金属含量变化较大，外源污染严重。对研究区重金属来源分析表明，矿渣堆积、工厂及小作坊污水排放、生活垃圾是研究区内最主要的污染源。

To provide the theoretical basis for establishing the ecological restoration system ,soil samples around gold mine in Tongguan county were collected to determine the contents of heavy metal including zirconium (Zr) ,cobalt(Co) ,selenium(Se) ,iron(Fe) and titanium(Ti) .The results showed that the lower contents of Zr ,Ti and Fe were observed in the investigated regions ,but the contents of Co and Se were very high in all sampled regions .The distribution characteristics of all heavy metals were homogeneous in the first investigated region and the third investigated region . The content variation of all heavy metals was obvious and serious soil contamination occurred in the fourth region and the fifth region .Analyzing the source of the heavy metals ,soil contamination mainly was caused by piling up mineral residue ,discharging the waste water ,dumping household garbage .
