摘　　要：以珠江口海域作为研究对象,以气象卫星FY＿1D数据为信息源,通过遥感监测值与准同步珠江口实测悬浮泥沙含量的对比分析,建立基于FY＿1D数据的悬浮泥沙含量遥感估算模型。研究表明,FY＿1D可用于近岸水域悬浮泥沙的遥感监测,在动态监测方面有明显优势,可作为现有海洋采样观测的补充手段。By the use of the meteorological satellite FY_1D data, estimated are the concentrations of sediment in the Pearl River. A remote sensing estimating model is proposed by analyzing the correlation of the FY_1D channel data for watercolor monitoring and synchronal field survey for suspended sediment concentrations. The result indicates that meteorological satellite FY_1D can be used to monitor the concentrations of suspended sediment in estuary as a kind of important assistant means of routine water quality sampling survey with its advantages of time and spatial resolution.
