摘　　要：岬湾海岸是世界上分布最为广泛的海岸形态,其形态特征可以反映岸线的长期冲淤变化趋势,相应的理论模型被提出来用以模拟平衡状态的岸线形态。莱州湾东岸从龙口港至刁龙嘴发育4个典型的岬湾海滩,本文利用常见的3个岬湾模型模拟该处海滩形态,并分析各模型的适用性,结果显示抛物线模型模拟结果适合本研究区,通过模拟和现场调查发现该区域绝大部分岸段将仍然处于侵蚀状态,人为作用在岸线的冲淤演化中影响巨大。Head-land bay beach is the most common coast in the world, and its shape is the reflection of erosion and deposition trend of a coast line. Accordingly, many model theories have been proposed in or der to emulate the shape of coast under balanced status. In Laizhou bay, from Longkou port to Diaolongzui, there are four typical cape bay coasts. In this article, an emulation of those coasts is made in order to analyze the present erosion and deposition status of this area. In emulation, three common theories were applied and an analysis of the applicability of those theories was also made.
