摘要分析了吕梁盆地70个表层土壤样品的磁化率值和Cu、Zn、Ni、Pb、Cr、Cd含量，并对其污染程度进行了评价。采用污染因子（CF）和污染负荷指数（PLI）评价重金属污染程度。土壤重金属含量均大于山西省农业土壤背景值。PLI值介于1.27至2.18之间，表明土壤污染严重。采用主成分分析和相关性分析对数据进行处理，识别重金属来源。Cu、Zn、Ni和Pb对总变异的贡献率为31.2%，说明这些元素主要来源于农业化学和大气沉降。耕作土壤磁化率与Cu、PLI呈正相关。这项研究表明，磁化率测量可以作为一种技术，其中不同类型的土壤污染可以区分，也可以用来快速监测异常的地区，可能需要昂贵和耗时的详细化学分析。
ABSTRACT The values of magnetic susceptibility and Cu, Zn, Ni, Pb, Cr, Cd concentrations of 70 topsoil samples were analyzed and assessed for soil contamination in the Linfen basin of China. The contamination factor (CF) and pollution load index (PLI) were used to assess the degree of heavy metal pollution. All heavy metal concentrations in the soil were greater than the background values of Shanxi agricultural soils. PLI values ranged from 1.27 to 2.18 indicating significant soil contamination. Principal component analyses and correlation analyses were adopted for data treatment to identify heavy metal sources. Cu, Zn, Ni, and Pb were responsible for 31.2% of the total variance suggesting that these elements mainly originated from agrochemistry and atmospheric deposition. A positive correlation of magnetic susceptibility with Cu and PLI were observed in cultivated soils. This study shows that magnetic susceptibility measurements can be used as a technique in which different types of soil pollution can be distinguished and can also be used to rapidly monitor anomalies in areas that might require expensive and time consuming detailed chemical analyses.
