摘要
研究通过对临汾市尧都区农田土壤剖面系统的测量与采样,分析了土壤磁化率与重金属元素垂直变化特征及其相关性.结果表明:磁化率随深度增加而递减,重金属元素Cu、Ni、Cd含量随深度增加而递增,Zn的含量随深度增加而递减.磁化率与重金属元素Cu、Ni、Cd含量呈极显著负相关,而与Zn含量呈显著正相关.频率依赖系数与重金属元素含量不相关.说明磁性物质对重金属元素含量有一定的指示作用,可以通过检测褐土中磁化率快速地诊断褐土中重金属的含量及污染状况.
Based on systematical measurement and sampling in farmland Brown Soil profile of YaoDu area of linfen,the variational characteristics of magnetic susceptibility and heavy metal elements and its correlation was analyzed.The study revealed that magnetic susceptibility neg-atively correlated with the depth;the content of heavy metal elements Cu,Ni,Cd negatively correlated with the depth while the content of Zn positively correlated with the depth.Magnetic susceptibility and the content of heavy metal elements Cu,Ni,Cd is extremely significant negative correlation,and has a significant positive correlation with the content of Zn.Frequency dependent susceptibility and the content of heavy metal elements is relevant.It shows that the magnetic material have indicative function for heavy metal content,it is feasible to analyze rapidly heavy metal content and the pollution status of Brown Soil through the test of magnetic susceptibility.
