| 摘 要： | 为研究黄河三角洲海底冲刷演变规律,2004年6月和9月,在黄河三角洲北部、飞雁滩以东岸段进行了2次共21条水深剖面测线的调查工作。通过1985年、1999年两期历史水深资料与本次实测水深资料的对比研究发现:自1985年以来,研究区一直处于冲蚀状态,1999年以后局部区域出现微弱淤积,侵蚀中心逐渐向东南、向岸迁移。测区总体演变趋势以侵蚀为主,强度逐渐减弱,并向冲淤平衡缓慢过渡。

| Abstract: | Changes in the morphology of the coastal zone were monitored in June and September 2004 in the northern area of the Yellow River delta. Through collecting and comparing water-depth data of 1985 and 1999, we got the result that this area was in the condition of erosion from 1985, after 1999, part of the area seemed to be in slight accretion, and the center of the erosion moved southeastwards and towards the shore. The total evolution trend is that this area will keep eroded, but the intensity will decline gradually into balance of accretion and erosion. |
