Abstract Because the Surface-Waters are polluted with different pollution types and degrees, the characteristics of reflectance spectrum for them are different. These differences can be actually recorded on the color aerophotograph by the form of color density difference. The correlation between the reflective color density ratio of the surfacewater image on the color aerophotograph and the combined pollution index of the water is emphatically studied in this paper. The statistical relationship between them is given. so, It is possible to determine semiquantitatively the combined pollution degree of the surface-water based on color aerophotograph.
