测量了武汉市东湖周边3个采样区60个土壤样品的磁化率及24个代表样品的重金属元素质量分数,对土壤磁化率和重金属元素质量分数进行了相关分析与聚类分析,探讨应用土壤磁化率参量及测量技术对大范围区域污染环境评价的指示意义.结果表明,土壤磁化率与重金属元素Ca、Cu、Pb、Sr、Zn质量分数显著相关,相关系数分别高达0.930,0.836,0.864,0.879和 0.879;重金属元素Ba、Cr、Fe、Mg、Mn质量分数与磁化率中度-弱相关,相关系数分别为0.447,0.303,0.557,0.528,0.333.聚类分析结果表明,不同采样区地表土壤的污染源之间存在一定差异.这些结果为应用土壤磁化率(尤其是原位磁化率)测量技术在该区进行大尺度和高精度环境评价提供了基础.

The magnetic susceptibility measurement were performed on 60 samples from the topsoil around the East Lake, Wuhan, China. Heavy metal analysis of 24 representative samples were undertaken, using correlation analysis and cluster analysis. The measurement and analyses are made to see whether these techniques are feasible for the environment evelauation on a large scale. The correlation results show that the susceptibility of topsoil is strikingly relevant to Ca, Cu, Pb, Sr and Zn, with the correlation coefficient 0.93,0.836,0.864,0.879 and 0.879 respectively, while heavy metals Ba, Cr, Fe, Mg and Mn show a moderate correlation, with correlation coefficient respectively, 0.447,0.303,0.557,0.528,and 0.333. The cluster analysis results reveal that different sampling areas have different features in topsoil susceptibility and heavy metals content because of their different contamination. All this shows that the magnetic susceptibility (especially susceptibility in situ) is of great potential as a proxy for large-area heavy metals pollution evaluation.
