Abstract

Abstract

The eco-environment in the Shuichang iron mining area has continuously deteriorated after many years of extensive and substantial mining operations.Surface spectral testing indicates that the spectral curves of vegetation commonly display the phenomenon of "blue shifts of red edges and down shifts of green peaks", which is a typical aberrance character of poisoning of iron compounds.From the operation site to peripheries, the values of red edge "blue shifts" have a trend of decreasing markedly, which indicates that the poisoning symptom of iron compounds is reduced gradually.Testing and analysis of the typical surface spectral features of the mine furnish important evidence for the determination of characteristic spectral bands or diagnostic spectral bands of various surface features and also provide a theoretical basis for the hyperspectral remote sensing survey of the eco-environment of the mine.
