摘　　要：由于海岸带活跃且脆弱,快速准确的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.遥感技术为海岸线的提取提供了重要手段,弥补了传统海岸线测量时,费时费力与部分地区难以到达等不足.基于海岸线特征提取的思路,总结当前国内外海岸线提取的主要方法.其存在问题为:影像信息不充分、验证精度低、海岸线误认为水边线等.针对以上不足进行探讨,最后对基于遥感的海岸线自动提取研究进行展望.The coastal zone is quite active and frail. For the sea area management, it is very important to monitor the dynamic change of coastline rapidly and accurately. Remote sensing technology provides an important means for the extraction of coastline. It makes up for the deficiency of coastline traditional measurement, parts of time-consuming and difficult to reach, etc. Based on the features of remote sensing image and coastline, we summarized the main methods of coastline extraction at home and abroad. Current research problems included inadequate image information, validation, low precision, the coastline as water line, etc. In order to improve and verify the above shortage ,finally the coastline automatic extraction based on remote sensing was discussed.
