摘要 海岸带是比较活跃和脆弱的地段,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。遥感技术具有宏观、快速、综合、高频、动态和低成本等突出优势。重点介绍了利用阈值分割、边缘检测、色差算子提取、区域生长提取及神经网络分类等方法自动提取瞬时水边线,通过潮位校正进而提取海岸线的研究进展,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 coastal wetland is quite active and frail. 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 macro- scopic, fast, comprehensive, high-frequency, dynamic, low cost and such prominent advantages. The progress of research in coastline extraction based on RS was emphasized, the advantage and disadvantage was analyzed, and the future research orientation was forecasted based on its existent insufficiency in brief.
