Abstract: The significance of remote sensing techniqe in water quality monitoring is analyzed and the theoretical basis of using remote sensing technology to achieve water quality parameters is explained.Through analysis of the existing study results of water quality monitoring based on remote sensing technique in recent years,the advantages and disadvantages of three main water quality monitoring methodsmodel analysis method,semi-empirical analysis method and empirical analysis method) are summarized,the direct water quality parameters and indirect water quality parameters that can be acquired by using water monitoring technique based on remote sensing are discussed.Based on the above study results,the further development directions of water quality monitoring based on remote sensing is proposed.

Key words: Water monitoring based on remote sensing, Model analysis method, Semi-empirical analysis method, Empirical analysis method, Water quality parameter, Study progress
