Water eutrophication is a global water environment problem. Urban water bodies are greatly affected by human activities. It is of great significance to study its eutrophication. The purpose of this paper is to study the detection and evaluation system of lake water eutrophication based on remote sensing technology. Use C#, IDL and ArcGISEngine for overall system development. The system takes the inversion of water chlorophyll a concentration as the main line, realizes the preprocessing of the original image, and conducts research on the spatial distribution of chlorophyll concentration through different models. The chlorophyll a concentration retrieved by remote sensing was evaluated and analyzed by the water body eutrophication index, and finally the evaluation results were verified. The model was verified by calculation to be ideal and can accurately and reliably evaluate the water body eutrophication degree of Lake M. It also proves that the detection and evaluation system of lake water eutrophication based on remote sensing technology is feasible.
