| Abstract: | This paper has dealt with such spectral features of vegetation in the mining area as the intensities and locations of green peak, red valley and infrared reflectance plateau and the slopes and locations of red edge and blue edge altered under the stress resulting from characteristic contamination of acid, alkali, heavy metals etc. The advances in the extraction of contamination information of vegetation in the Dexing copper mine based on spectral features of all kinds of plants are discussed on the basis of hyperspectral imaging data. The spectra of various plants were analyzed, and then spectral parameters (red edge position and absorption depth) were used to study the information extraction and reveal the general contamination situation of vegetation in the Dexing copper mine. The project is helpful to the whole process of diagnosing and monitoring mine pollution. |
