摘要
河流带来的泥沙不断淤积在河口地区,造成河口海岸不断向外延伸发展。遥感能大面积实时地获得地面资料,为河口海岸的动态研究提供了有效的手段。本文以珠江口伶仃洋遥感应用为例,对悬浮泥沙、水深等遥感专题信息的计算机定性定量处理进行了讨论。
The sediment brought by river at estuary causes the development of estuary coast. Remote sensing offers a useful means in monitoring the dynamic changes of estuary coast. The information processing of special subject of remote sensing is discussed in this paper and some practicable methods of computer processing are concluded. The results that information processing of special subject of remote sensing is used on the research of suspended sediment, bathymetry, under-water topography and the dynamic changes in Lingdingyang, such as quantitative patterns of suspended sediment and Preliminary experiment of quantitative analysis of bathymetry in Lingdingyang, are presented in this paper. Multi-phase images processed by computer are also used on the dynamic monitoring of Lingdingyang.
