Compared with traditional satellite remote sensing and manned aircraft remote sensing,unmanned aerial vehicle(UAV)remote sensing has the advantages of high spatial and temporal resolution,low altitude flight under the cloud,high mobility,etc.,which solves the problems existing in traditional water quality monitoring work and it can timely grasp of the hydrological situation,achieve high-efficiency results in real-time monitoring of water quality,provide a new opportunity and way for water quality monitoring and evaluation.The remote sensing inversion method of UAV has gradually become an important technical means for monitoring and evaluating the water quality of inland water bodies,which can reflect the more comprehensive distribution of water quality in time and space.This paper reviews the characteristics of UAV remote sensing,and describes the principle of UAV remote sensing water quality monitoring,monitoring objects,monitoring methods and the research progress of UAV remote sensing water quality monitoring and the factors affecting the accuracy of water quality monitoring.On this basis,the remote sensing monitoring of UAV water quality is prospected,and it is proposed that the UAV hyperspectral remote sensing technology is expected to become the focus and direction of studying the eutrophication of largescale spatial and temporal waters,and can obtain a spatial retrieval map of various water quality parameter concentrations which comes from digital transmission modules under high bandwidth.
