摘　　要：高光谱遥感以其快速、非接触的测量方式,符合当前大范围、快速监测的需求。对高光谱遥感在土壤重金属污染方面的研究成果进行综述,重点归纳了不同重金属种类污染土壤光谱特性。高光谱遥感在土壤重金属污染方面存在重金属光谱信号微弱、精度有限、时效性不理想和对Cd、Hg等毒性较强但无光谱特征元素检测困难等问题,呈现仪器性能有所提升、数据处理方法有所创新和多源信息集成处理的发展趋势。Hyper-spectral Remote Sensing meets the needs of large-scale and rapid detection for its fast and non-contact measurement. This article reviews the achievements of hyper-spectral remote sensing in soil heavy metal pollution and summarizes the spectral properties of different types of heavy metal contaminated soil. Many problems exist in hyper-spectral remote sensing detection of heavy metal pollution soil, for instance, the weak spectrum signal of heavy metals, the limited accuracy, the unsatisfactory timeliness and the detection difficult of some no spectral elements like Cd and Hg with highly toxic. Furthermore, it is showing the trend that the improve of instrument performance, the innovation of data processing methods and integrated applications of multi-source information of the detection in heavy metal pollution soil.
