摘　　要：海岸线位置的确定是海岸带和海岛礁测绘的重要内容。快速而准确地监测海岸线的动态变化对于海域的使用管理具有十分重要的意义。遥感技术具有快速、动态、大范围、宏观等突出优势。重点介绍了基本遥感影像提取瞬时水边线,通过潮位校正进而提取海岸线的研究进展,提出了基于潮间带DEM和潮汐模型的海岸线提取方法,分析了各种提取方法的优缺点,并就其存在的不足展望了今后的研究方向。The coastline position determination is the important content of the coastal zone, island and reef surveying. It is very important to monitor the dynamic change of coastline rapidly and accurately regarding the sea area use and management. Remote sensing technique has fast, dynamic, large scope, macroscopic and such prominent advantages. The advances in coastline extraction based on remote sensing was emphasized, the method in coastline extraction based on the DEM of the intertidal zone and tidal model was proposed, the advantage and disadvantage were analyzed, and the future research orientation was forecasted based on its existent insufficiency in brief.
