摘　　要：为了治理矿山环境土壤重金属污染,提出矿山环境土壤重金属污染状况监测方法研究。选取手持地物光谱仪获取矿区环境土壤光谱数据,通过断点修正、标准归一化、连续统去除与基线校正四步骤对土壤光谱数据进行处理,选取光谱指标信息,分析重金属质量比之间的相关性,提取土壤光谱特征波段,构建重金属含量估算模型,制定土壤重金属污染程度判定规则,从而实现了矿区环境土壤重金属污染状况的监测。仿真实验结果显示提出方法重金属含量监测误差较小。In order to control heavy metal pollution in mine environmental soil,the monitoring method of heavy metal pollution in mine environmental soil was put forward.The handheld ground object spectrometer is selected to obtain the spectral data of environmental soil in mining area,and the spectral data is processed through four steps:breakpoint correction,standard normalization,continuum removal and baseline correction.The spectral index information is selected and the correlation between heavy metal mass ratios is analyzed.The characteristic band of soil spectrum is extracted and the estimation model of heavy metal content is constructed.The determination rules of heavy metal pollution degree in soil are formulated,thus realizing the monitoring of heavy metal pollution in environmental soil in mining area.The simulation results show that the error of heavy metal content monitoring by the proposed method is small.
