摘要:
莱州浅滩是山东半岛北部著名的海岸地貌,位于刁龙嘴外,呈NW—SE向延伸,浅滩众多,水道纵横,地貌状况复杂。目前对莱州浅滩的形成过程、沉积特征少有研究,或只针对某一方面有所论述。通过实地调查,并对资料进行分析,研究了莱州浅滩的沉积物分布特征、矿物组成、地貌特征、储砂量和演化过程,认为波浪作用是莱州浅滩形成的主要动力,控制着研究区地貌形态分布和莱州浅滩演化趋势。通过以上研究,结合莱州浅滩现状,指出了其目前在开发与保护中存在的问题,并提出了合理开发利用的建议。

Abstract:
The Laizhou Shoal is famous for its coastal topography in North Shandong Peninsula. Located at the edge of Diaolongzui and stretching from NW to SE, it is divided by numerous waterways and different size of shoals, which makes up its complex topographical features. Current study on the evolution history of the Laizhou Shoal seldom focuses on its formation and sediment features, except few descriptions. By field investigation and indoor sample analysis, the sediment distribution, mineral composition, topographical feature, sand reservoir and evolution history of the Laizhou Shoal are studied. It is concluded that the wave effect is the main driving force for the formation of the Laizhou Shoal and controls its topographical distribution and evolution pattern. In combination of the current status of the Laizhou Shoal, some problems and suggestions are pointed out based on this study.
