土壤重金属检测与电阻率特征分析

Soil Heavy Metal Detection and Resistivity Analysis

摘要: 土壤重金属污染已成为我国的突出环境问题之一，而环境地球物理学已逐渐在土壤重金属环境污染调查与监测方面扮演越来越重要的角色，其中电阻率法为环境地球物理学常用方法之一，本文针对同一点位的土壤样品进行重金属检测与电阻率测试，通过试验进一步证明：土壤重金属含量与电阻率呈负相关性，即土壤中重金属含量多、电阻率值相对小，重金属含量少、电阻率值相对大，两者具有很好的对应关系，这为采用电阻率法应用于重金属污染土壤调查与监测提供参考。

Abstract: Soil heavy metal pollution has become one of the prominent environmental problems in China, and environmental area physics has gradually played an increasingly important role in environmental investigation and monitoring, among which resistivity method is one of the common methods of environmental geophysics. This paper conducted heavy metal detection and resistivity test for the same soil sample, and further proved through experiments: The heavy metal content in soil is negatively correlated with the resistivity, that is, the heavy metal content in soil is high and the resistivity value is relatively small, while the heavy metal content is low and the resistivity value is relatively large. The two have a good corresponding relationship, which provides a reference for the application of resistivity method in the investigation and monitoring of heavy metal contaminated soil.
