|Aquatic vegetation plays an important role in stabilizing sediment, purifying water quality and balancing aquatic ecosystem in lake and reservoir ecosystem. Monitoring the change of aquatic vegetation is of great significance to the monitoring of lake and reservoir ecosystem. In this paper, the methods of extracting aquatic vegetation from hyperspectral and multispectral optical satellite remote sensing data at home and abroad are summarized and analyzed, especially for the determination of threshold involved. The spatial and temporal distribution and change of aquatic vegetation in typical research areas and their relationship with water quality are introduced. Finally, some prospects for remote sensing monitoring of aquatic vegetation are given.
