Advance in remote sensing of water quality

As a new method of water quality,more importance has been attach to remote sensing technique,which has been applied in measuring and retrieving of water quality parameters.This article generalized the significance of remote sensing technique in water quality,summarized water quality index which is available for remote sensing monitoring,introduced the spectrum feature of clear water,Case-Ⅰwater,Case-Ⅱwater and polluted water,emphatically discussed the base method in remote sensing of water quality as well as the research and development on nutrients,organic pollutants,trophic state index.Finally,the article pointed out the principal problems and looked into the feature trend of remote sensing of water quality.
