摘要
利用从１９７３年至１９９３年美国陆地卫星ＭＳＳ、ＴＭ数据影象等不同片种、２０多个不同时期的伶仃洋遥感资科，结合同步或准同步水文观测数据，通过计算机、光学图象处理和遥感动态信息分析，获得对伶仃洋水沙输移特征和滩槽冲淤变化规律的宏观认识，其成果在伶仃洋治理规划研究中发挥作用。
Based on different kinds of photos, data and images of US Landsat and TM from 1973 to 1993 and reremote sensing data of Lingdingyang Sea in more than 20 diffenent peneds in combination with data obtained from synchronous and quasi-synchronous hydrologic observations,objective knowledge of characteristics of water and sediment transport and the law of scouring and silting of channel and beachland was obtained through computer,processing of optic images and analysis of remote sensing dynamic information.'l'he results have played lin important role in the investigation for the improvement plan of Lingdingyang Sea.
