1855年，黄河改道，经大清河在山东利津县东北汇入渤海。到目前为止，黄河已经改变了十次左右的常规，形成了由七个亚三角洲沉积组成的近代和现代黄河三角洲。在分析工程钻探资料沉积序列的基础上，结合黄河三角洲近现代航道和六条海岸线的变化，计算出工程钻探的地面高程。利用ARC/INFO和ERDAS软件制作了1855、1937、1954、194、1977和1991年的三维地形图。结果基本反映了黄河三角洲的二维演变和地貌形态。
In 1855, Yellow River changed its routine and went into Bohai sea at the northeast of Lijin County, Shandong Province through the Daqinghe River. Yellow River has changed its routine about ten times so far, and built neoteric and modern Yellow River Delta, which is made of seven sub-delta deposits. On the basis of analysis of deposit sequence of engineering drill data, integrating with the changes of the routes of the neoteric and modern Yellow River Delta and six coastlines, the ground elevation of engineering drill can be calculated. Using software ARC/INFO and ERDAS, three-dimension relief maps in 1855, 1937, 1954, 1964,1977 and 1991 are produced. The results reflect the two-dimension evolutions and relief forms of the Yellow River Delta basically.
