Abstract: In this article, Jisan coal mine was selected as investigated the relation between field vegetation reflectance
research area, we collected P. Tomentosa leaves’ reflectance and elevated concentrations of the heavy metal in river
and measured the concentration of heavy metal in P. floodplain soils. The relations were evaluated bination
Tomentosa leaves. According to the principles and methods of with two spectral vegetation indices: the Difference
remote sensing biogeochemistry, We employed spectral Vegetation Index (DVI) and the Red-Edge Position (REP).
derivative technology, local continuum removal, red edge Pablo et al[4] investigated reflectance properties and
extracting to analyze the spectral features. The spectral physiological responses of Salicornia virginica to heavy metal
information from P. Tomentosa field spectral data showed and petroleum contamination. The high degree of correlation
that, in general, with the increase of heavy metal concentration be
