| 摘要: |
| 根据历史和现代调查资料,北仑河口河槽演变主要是受河流动力和海洋动力共同作用。在不同的区域,其动力作用的程度大不相同。在河口北侧地区,作用较为强烈,河槽、边滩、沙洲等发生明显变化,河岸也出现侵蚀现象。 |

| Abstract: |
| The comparative analysis between the historic materials and the on-the-spot investigation in the Estuary of Beilunhe were carried out. The results showed that the succession of the riverbed was mainly associated with the joint effect of both river and marine dynamics. But the degrees of the dynamic functions varied greatly in different areas.It was more violent in the northern side area of the estuary than that of the other. The riverbed, beaches across and sandbar of the northern area changed obviously.The riverbanks were also eroded. |
| Key words: estuary succession of riverbed river dynamics marine dynamics |
