在分析黄河三角洲及附近海域潮汐规律的基础上，提取了高潮线、海岸线和低潮线等海岸带的基本要素，海岸线和高潮线的提取采用简便易行的目视解译方法直接获得；对于较难提取的低潮线，引入了遥感水深理论，建立水深模型，结合当地潮汐、潮位资料和DEM数据进行了推算，最终完成黄河三角洲经济区海岸带的提取工作。结果表明：利用水深遥感模型反演得到的低潮线虽然有一定误差，但并不影响进一步研究，与传统方法相比具有快速、简捷的优点。

Based on the analysis of tidal regime around the Yellow River delta and nearby water,this study extracted many coastal-zone basic ele-ments including the high water line,coastline and low water line. The extraction of the high water line and coastline directly used a very simple method,i. e. visual interpretation method. However,in the extraction of low water line,the assay introduced the RS depth theory and built a water-depth model,combined with the information of the local tides,tide-level and the DEM data and finally completed the extraction of the coastal zone in the Yellow River delta economic area. The result shows that the low water line,which is inverted by the Depth-RS Model,exists some errors, while,it does not affect further study. Instead of,this method is faster and more simpler comparing with the traditional method.
