| Taking three water bodies (a, b, c) in a heavy metal mining area as the study region, the remote sensing monitoring data from Aster satellite sensor was collected, the standard plate and the target water bodies were measured by spectroradiometer, the spectral reflectance of the target water bodies was calculated to analyze the spectral reflection characteristics of regional water bodies subjected to heavy metal pollution, and realize the remote sensing monitoring of heavy metal polluted wastewater based on spectral analysis. The results showed that the heavy metal pollution degree in area a gradually increased from deep water to shallow water, and the water body was orange-red. In area b, the degree of heavy metal pollution gradually increased from shallow water to deep water, and the water was brownish red. The water in area c was not polluted by heavy metals, and the water in the whole area was copper-green. The results were consistent with the situation of heavy metal pollution in each water body collected on site. |
