摘要/Abstract

摘要：

岬湾砂、砾质海岸是海岛、海岸带重要的旅游资源, 具有较高的社会经济和生态价值, 长期以来备受关注。本文以浙江朱家尖岛东岸的5个代表性岬湾海滩为例, 基于2019年台风季节早期、中期及晚期测量获得的海滩地形和沉积物数据, 结合海滩近岸的水动力数据, 分析了砂质海滩和砾石海滩这两种不同类型岬湾海滩的沉积地貌动态变化。结果表明, 朱家尖岛东岸5个海滩在台风季节出现了不同的体积变化, 大沙里、东沙、千沙、乌石塘和小乌石塘海滩的单宽体积变化分别为11.93m³·m^-1、-54.41m³·m^-1、-19.75m³·m^-1、2.19m³·m^-1和-1.96m³·m^-1。砾石滩较砂质海滩更为稳定, 无人类活动干扰的砂质海滩在台风季节侵蚀更少、变化更小。台风季节大沙里、东沙、千沙、乌石塘和小乌石塘海滩表层沉积物的平均粒径分别为2.47Փ、2.24Փ、2.64Փ、-5.96Փ和-6.03Փ, 粒径粗化和离岸输运是5个海滩表层沉积物在台风季节的主要表现, 砂质海滩的沉积物粒度特征变化比砾石海滩要大。沉积物粒径、台风强度及台风期间的主要波向与海滩走向之间的关系、海岸工程这3种因素都可能对海滩在台风季节的沉积地貌动态变化产生影响。本文研究结果可为台风季节的海滩管理提供参考。

Abstract:

The embayed sandy and gravel beaches are important tourism resources in the coastal zone of islands, with high socio-economic and ecological values and having received study attention for years. This study focuses on five representative embayed beaches on the east coast of the Zhujiajian Island in Zhejiang Province. The beach topography and sediment data were obtained from three field campaigns in the early, middle and late stages of the 2019 typhoon season, and the nearshore hydrodynamic data were also collected and analyzed. Then, the dynamic changes of topography and sediment characteristics of five different embayed beaches were detected. The results show that the five beaches experienced different volume changes during the typhoon season, i.e., 11.93 m³·m^-1(Dashali), -54.41 m³·m^-1(Dongsha), -19.75 m³·m^-1(Qiansha), 2.19 m³·m^-1(Wushitang) and -1.96 m³·m^-1(Xiaowushitang), respectively. The gravel beaches were more stable than the sandy beaches, and the sandy beach without human activity is less eroded during the typhoon season. The mean grain size of surficial sediments on Dashali, Dongsha, Qiansha, Wushitang and Xiaowushitang during the typhoon season are 2.47 Փ, 2.24 Փ, 2.64 Փ, -5.96 Փ and -6.03 Փ, respectively, with coarsening and onshore transport being the main performances of their changes. The change of sediment grain size on sandy beaches is more significant than that on the gravel beaches. The sediment grain size, the energy level of typhoon, and the angle between the main wave direction during the typhoon and the beach orientation, and coastal engineering can have impacts on beach morphological variation during typhoon seasons. This research can provide reference for the beach management during typhoon seasons.

Key words: embayed beaches, profile morphology, grain size characteristics, human activities, typhoon season
