水生态环境遥感监测研究进展OA

Water environment pollution is one of the prominent issues affecting global water security.Water resources distribution,utilization,and water environment vary dramatically in China.Therefore,scientific monitoring,evaluation,and planning of the water eco-environment using remote sensing and spatial information technologies are essential.This study analyzes the problems with water eco-environment and the limitations of traditional monitoring methods,highlighting the advantages of remote sensing technology in acquiring wide-area,continuous,and real-time data.It reviews the progress of remote sensing applications in water ecological monitoring,water environment parameter inversion,non-point source pollution estimation,monitoring of key water diversion projects,and response to sudden pollution events.The study also anticipates trends in systematic governance of water eco-environment at the watershed level,new remote sensing technology and platforms,multi-source data fusion and cross-scale monitoring,and the development of an integrated"space-air-ground"water quality monitoring system.As remote sensing technology rapidly advances,it will significantly contribute to the protection and management of the water eco-environment.
