| 摘 要： | 以潼关县某金矿排水沟附近土壤为研究对象,对土壤中Mn,Cu,Zn和Pb四种重金属含量进行分析,为金矿周围土壤污染治理及人工生态修复提供依据.实验结果表明:Pb含量在研究区内累积严重,Cu次之,而Mn累积较轻;四种重金属在第四样区内的含量变化均最大,变异系数均最高;四种重金属在35个样点的分布特征中,Mn,Cu,Zn和Pb在样区内含量变化规律相似,可能存在相同或相近污染源.

| Abstract: | The soil around gold mine in tongguan county was chosen as the research object,and the contents of heavy metal including manganese,copper,zinc and lead were determined,the theoretical basis for establishing the man-made ecological restoration system was provided.The results show that the contents of lead are all very high in all sample regions,and copper is second,and manganese is lower than others as far as the national background value is concerned.The variation coefficients of all heavy metal are the highest in the four sample region.The distribution characteristics of four kinds of heavy metals are similar,it may be caused the same or similar pollution sources. |
