摘　　要：渤海湾是中国典型的淤泥质海岸带,应用不同时期的历史资料、地形图、航空照片及多时相的MSS、TM、ETM遥感数据,经计算机处理,进行信息增强及信息复合,提取了百年来海岸线变化信息,划分为侵蚀、淤积和稳定不同类型岸段,表明渤海湾西岸泥质海岸带近百年来已发生了"缓变型地质环境变化"中的"相对快速的变化"。The Bohai Bay Coast is the most typical muddy coast in China. Through the collection and subsequent computer-processing of various sorts of data such as historical documents, topographic maps measured repeatedly in the past 130 years, air-photos, MSS, TM and ETM images for different time-phases, the authors obtained a number of results refined by information enhancement and information overlapping. Such results are helpful to reveal the shoreline migration of the area in the last century.
