Abstract

The domestic interior water body was monitored Based on an HJ-1 satellite multi-spectrum data. Chlorophyll a density is inverted from the empirical model based on the different area and different season. Suspension density inversion is based on the photobiology model of near-infrared waveband method. Based on chlorophyll a and the suspension density, the interior water body trophic level index is monitored using remote sensing data. There was a synchronized observation experiment in Lake Chaohu in June, 2009. The measurement data confirms the water quality parameter inversion algorithm. The results indicated that the chlorophyll a density inversion precision is inferior to the suspension density, but both inversion precision meets the water environmental monitoring service demand.
