Abstract：Trough field measurements of six kinds of typical vegetation in the Yellow River Delta with a visibel-nir field spectroradiometer, analysis and extraction of vegetation discrimination spectrum work are carried out based on the original spectral reflectance spectrum and continuum removed spectrum. The main work and results include: (1) A spectrum discriminative lookup table of original spectrum and continuum removal spectrum between every 2 typical vegetation species through the discrimination method is established, and the separable spectrum between every vegetation specie with other 5 vegetation species are obtained. (2) Then the impacts of continuum removal method for vegetation separable feature spectrum extraction is analyzed, the result reveal that for Suaeda glauca, Gossypium spp, Sophora japonica, and Salix babylonica the discriminative spectrum are broadening through continuum removal transformation.
