| 摘 要： | 通过对台风“米雷”登陆前后山东半岛东部8个滨海沙滩地形地貌的现场调查以及一年后的重复调查对比分析了沙滩地貌形态的变化,并依据台风期间的风要素计算和评估了台风期间沙滩的沿岸输沙和横向输沙趋势,探讨了在热带风暴发生频次较低的地区沙滩的风暴响应模式和海岸恢复规律。研究结果表明,台风造成横向和纵向输沙量的增加和输沙方向的逆转是造成沙滩形态改变的主要因素,而在米雷登陆前的阶段横向和纵向输沙作用最为强烈。研究区内沙滩的风暴响应模式主要表现为侵蚀陡坎的形成和滩肩或滩面的侵蚀后退。与其他台风频发的区域不同,在研究区台风是一个偶然的强动力事件,因此台风特征对沙滩的风暴响应的作用更加明显。而沙滩剖面形态的作用,仅仅在耗散型沙滩上有所体现。此外,沙滩的走向是控制风暴作用强度的主要因素,并且与沙滩风后恢复密切相关。

| Abstract: | Eight representative beach profiles on the eastern coast of the Shandong Peninsula are observed and measured in 2011 and 2012 to determine the coastal processes under the lower tropical wind speed condition and the beach response to and recovery from the tropical storm Meari in a rare typhoon region. The results show that it is the enhancement and directional change of cross-shore and longshore sediment transports caused by Meari that leads to the beach morphological changes, and most of the sediment transports occur during the pre-Meari landing phase. The erosional scarp formation and the berm or beach face erosion are the main geomorphological responses of the beaches to the storm. The storm characteristics are more important than the beach shapes in the storm response process of the beaches on Shandong Peninsula. The typhoon is a fortuitous strong dynamic event, and the effect on the dissipative beach is more obvious than it is on the reflective beach in the study region. Furthermore, the beach trend is the main factor that controlls the storm effect intensity, and it is also closely related to the recovery of the beach profiles. |
