摘　　要：传统的咸潮监测手段受限于站点分布和时间分辨率,难以实现大范围、长时间序列的咸潮上溯动态监测。近年来遥感影像日益丰富、模型算法迅速发展,卫星遥感技术为传统监测方法提供了有效的补充。综合评述了珠江河口水表盐度遥感反演领域的研究进展,首先详细阐述了当前应用的主要遥感数据源和反演模型,包括低空无人机、航空与星载微波遥感、星载光学遥感;随后从模型普适性、影像覆盖能力、垂向盐度监测等方面论述了遥感技术在支撑咸潮监测中面临的问题;最后对珠江河口水表盐度遥感监测的未来研究方向进行了分析与展望。Traditional methods of saltwater intrusion monitoring are constrained by the spatial distribution of monitoring sites and temporal resolution,making it difficult to achieve extensive and prolonged sequence dynamic monitoring of saltwater intrusion.In recent years,the increasing abundance of remote sensing imagery and rapid development of model algorithms have provided effective supplements to traditional monitoring methods.This review comprehensively discusses the research progress in the field of remote sensing retrieval of surface salinity in the Pearl River Estuary.It begins with a detailed exposition of the main remote sensing data sources and retrieval models currently in use,including low-altitude unmanned aerial vehicles,airborne and spaceborne microwave remote sensing,and spaceborne optical remote sensing.Subsequently,the paper addresses the issues faced by remote sensing technology in supporting saltwater intrusion monitoring from aspects such as model universality,image coverage capability,and vertical salinity monitoring.Finally,future research directions for remote sensing monitoring of water surface salinity in the Pearl River Estuary are analyzed and prospected.
