摘　　要：以河北省唐山市曹妃甸地区的海岸线为研究对象,选取ETM遥感影像进行低通滤波、中值滤波以及均值平滑处理。运用边缘检测方法中的修复归一水体指数算法(MNDWI)和Soble算法,实现了对曹妃甸地区的海岸线的自动提取。两种提取方法相比较的结果表明,Soble算法比修复归一化水体指数法提取精度更高,更适合曹妃甸地区的海岸线提取。This article takes the Hebei Province CaoFeiDian coastline as the object of study. Processing methods of the ETM remote sensing image are Low-pass filter,median filter and mean smoothing. Using edge detection method of repair to the water body index algorithm（MNDWI）and Soble algorithm,the article implements the automatic ex-traction of CaoFeiDian coastline. Compared two extraction results show that the repair Soble operator method has a higher precision,it suitable for coastline extraction of CaoFe iDian area.
