| 摘 要： | 高光谱技术的快速发展为宏观、快速获取土壤中的重金属元素信息提供了有力支撑。选择云南大红山铜矿作为研究区，对其土壤进行采样，其中水样、底泥样和土壤样各30个，共90个样本。使用ASD光谱仪对样品进行光谱分析，借助ENVI软件对原始测量数据进行平滑与去噪处理，利用与重金属相关的官能团在VNIR和SWIR波段光谱吸收特征的变化提取光谱吸收特征参数。通过与预处理后研究区的HyMap遥感图像数据进行光谱相似度及光谱参数相似度的对比，验证了将ASD实测光谱与HyMap高光谱遥感数据结合监测研究区重金属污染的可行性。认为高光谱遥感在土壤重金属监测方面有着广泛的应用前景。

| Abstract: | The rapid development of hyper-spectral technology provides a solid support for the rapid access to macro-information of heavy metals in soil. This paper selected the Dahongshan copper deposit in Yunnan Province as a research area to sample its soil, including about 30 water samples, 30 bottom mud samples and 30 soil samples, a total of 90 samples, using ASD spectrometer to carry out soil spectral measurement of the samples, with ENVI software for the original acquired data smoothing and denoising. The spectral absorption characteristic parameters were extracted by the variation of the spectral absorption characteristics of the VNIR and SWIR bands of the heavy metal-related functional groups, and the spectral similarity and spectral parameter similarity were compared with the pre-processed HyMap remote sensing image data of the study area. Therefore, the feasibility study of using ASD field spectral and HyMap hyper-spectral remote sensing data to monitor heavy metal pollution in the research area is completed, which indicates a good future for hyper-spectral remote sensing in its application in soil heavy metal monitoring. |
