| 摘 要： | 根据辽东湾东岸12段砂质海岸的实测剖面、表层沉积物粒度以及收集的水文资料,对其海岸类型、海岸动力环境等特征进行了研究,并运用Dean参数Ω探讨了研究区砂质海岸的动力地貌特征。结果表明:研究区砂质海岸发育岬湾型和沙坝-潟湖型两种海岸类型,并受浪控型、过渡型及潮控型三种海岸动力影响。辽东湾东岸砂质海岸动力地貌特征根据Dean参数Ω可划分为消散型与过渡型两种,两者在辽东湾东岸相间分布。

Geomorphic Features of Sandy Coast Along the Eastern Coast of the Liaodong Bay |

| Abstract: | Based on measured sections,grain size of surface sediment and hydrological data of 12 segments of sandy coast along the eastern coast of the Liaodong Bay,the types and dynamic environment of the sandy coast are studied and the dynamic geomor-phological features of the sandy coast are also discussed by using Dean Parameter Ω. The results show that two types of coast,the cape-bay type and the barrier-lagoon type, are developed along the sandy coast in the study area,which are influenced by three types of coastal dynamic environments,i.e.wave controlled type,transitional type and tide controlled type.Based on the Dean ParameterΩ,the dynamic geomorphology of the sandy coast along the eastern coast of the Liaodong Bay can be divided into two types:the dissipative type and the transitional type.Both of them are alternatively distributed along the eastern coast of the Liaodong Bay. |
