摘　　要：为探索实现长江口水文、地形和生态的大范围、高频次、抗恶劣海况的高精度遥感监测技术,利用高分五号卫星,进行了星地同步监测方案试验,获取了建模所需高光谱大数据。采用函数拟合等数据建模方法,逐步建立了含沙量等水体参数的高光谱影像反演模型,并给出含沙量浓度反演模型的输出效果,最后指出后续深化研究方向。In order to explore the high-precision remote sensing monitoring technology of hydrology,topography and ecology of the Yangtze River Estuary in a large range, high frequency and anti severe sea conditions,the satellite earth simultaneous measurement test is carried out by using Gaofen-5 satellite,and the hyperspectral big data needed for modeling is obtained. The hyperspectral image inversion model of water parameters such as sediment concentration are established by using function fitting and other data modeling methods,which shows the output effect of the inversion model for sediment concentration. Finally,the further research direction is pointed out.
