| Abstract: | With the increasing application requirements of water conservancy industry in the new era, hyperspectral remote sensing has shown great potential in water ecology and water environment due to its unique advantages such as high spectral resolution and real time. It also has great potential in applications in water disaster and water resources. This paper introduces the principle of hyperspectral imaging, summarizes the development of hyperspectral payload at home and abroad, and focuses on the application of hyperspectral remote sensing to solve specific water problems, including monitoring of water bloom and aquatic plants, accurate discrimination of water bloom and water grass, inversion of chlorophyll concentration, quantitative estimation of suspended matter concentration and sediment content, real-time and large-scale flood disaster emergency monitoring, quantitative inversion of land surface hydrological parameters, estimation of evapotranspiration, and so on. In addition, the bottleneck problems in the application of hyperspectral remote sensing in water conservancy industry are summarized and analyzed. With the rapid development of hyperspectral imaging technology and increasing availability of hyperspectral data sources, the application of hyperspectral remote sensing in water conservancy will also enter a new stage. It is necessary to confront the needs of water conservancy industry at the new stage. We should enhance the research on multi-platform hyperspectral water conservancy elements stereoscopic monitoring and integration, construction of the standard spectrum database for typical feature elements in water conservancy, and new methods or new theories for water conservancy hyperspectral remote sensing information intelligent mining. |
