Abstract

The invention discloses a water quality monitoring method and a water quality monitoring device based on an adaptive model. The method comprises the steps of obtaining remote-sensing reflectivity data to be processed, setting a characteristic threshold value to extract a water body area as a collecting and study area; obtaining water quality data of the collecting and study area, conducting least squares correlation analysis on different wave bands or band combinations, comparing correlation coefficients to obtain the most sensitive wave band or band combinations, and establishing an adaptive water quality monitoring model based on the most sensitive wave band or band combinations. According to the water quality monitoring method and the water quality monitoring device based on the adaptive model, the problems that an existing water quality monitoring model is lack of automaticity, systematicness and universality are solved.
