Abstract:
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.
