一、前言本文所研究的海岸位于云台山以南、埒子口以北约22公里长的一段粉沙淤泥质的侵蚀海岸。这段海岸自1855年黄河北归山东入海以来,岸滩一直处于侵蚀的过程。由于岸线的不断后退,现今的海堤基本上已成为岸线(见图1)。
I. Foreword The coast studied in this paper is located on the eroded coast of muddy silt about 22 km north of Yuntaishan and south of Yuntaishan. This coast has been undergoing erosion since the Yellow River returned to Shandong in 1855. Due to the continuous retreat of the shoreline, today’s seawall has basically become a shoreline (see Figure 1).
