Abstract： In order to beter apply hyperspectral remote sensing technology and improve thequalityof water environment monitoring， the continuous frequency band of 400～2 500 nm is used to obtain the spectral characteristics of water reflection，and semi analytical modelsand machine learning algorithms are combined to invert parameters such as chlorophyll aand suspended solids.Atthe same time，unmanned aerial vehicle platforms are used to achieve sub meter level spatialresolution monitoringandsynchronous ground spectral verification.Theresultsshowthathyperspectralremote sensing technologycan effctively enhancetheidentificationaccuracyof algal biomassand heavymetalpollution，andcan dynamically track the diffusionpath of polution.The conclusion confirms that hyperspectral remote sensing technology can construct a large-scale，high-frequency water quality monitoring system，providing scientific basis for eutrophication warning and pollution control.
