摘　　要：海岸线变迁是黄河三角洲地区重大环境地质问题之一。本文应用RS、GIS集成技术,通过对黄河三角洲海岸线钓口段、黄河港段和河口段3个区段28年(1976—2004年)MSS和TM系列影像数据的分析研究,发现了1976年黄河人工改道后三角洲海岸线变迁的总体规律与趋势,即北部钓口地区不断侵蚀、后退,东北部黄河港地区基本稳定,南部河口地区不断淤积、前进。这一发现对该区域的资源开发、环境保护等具有重要的指导意义。The Yellow River is the second longest river in China and famous for its suspended riverbed, frequent diversion and huge amount of sediments. Coastline＇s movement is one of the major environmental geological problems in the Yellow River delta area. The authors analyzed the MSS and TM image data over 28 years （1976 to 2004） from the Diaokou, Huanghegang and Hekou reaches by using the integrated RS and GIS technique and found the general trend of coastline evolution after 1976＇s artificial diversion of the river, i.e.： continuous erosing and recessing of the Diaokou reach in the north, relative stability of the Huanghegang （Yellow River Harbor） reach in the northeast and continuous silting and advancing of the Hekou （river mouth） reach in the south. These findings may guide the resource development and environmental protection in the Yellow River Delta.
