摘　　要：热带风暴是一种频发的灾害性事件,其诱发的大浪及其伴生的风暴潮会在短时间内搬运大量沉积物,对海岸地貌、海底地形和海洋沉积的影响极为严重.总结了未来风暴变化趋势和风暴动力方面的研究进展,概述了近几十年来海滩风暴效应领域几个重要方向的进展,内容包括岸滩风暴灾害调查和研究、海滩风暴效应差异性研究、风暴作用下的泥沙运动和岸滩风暴响应沉积学特征等方面.从国内外的研究现状来看,我国在风暴作用下泥沙运动实测与定量分析、多因素耦合控制下海滩风暴效应差异和海滩风暴地貌过程等方面存在着明显的不足.作为我国海岸科学研究中必需又薄弱的环节,今后该领域的研究应该在强化野外现场实验和监测的基础上,深入探讨极端条件下的海滩过程,发展海滩风暴响应预测模型,并积极开展海滩风暴潮防护技术开发与应用.Tropical storms,which occur frequently in coastal areas,cause strong waves and surge storms that can transport vast sediments in a short time,heavily impacting coastal geomorphology,inshore topography and littoral sedimentation.Herein,studies of future trends of tropical cyclone development and progress in storm hydrodynamic studies are summarized.In addition,the status of research on storm beach effects in the recent decades,including investigations and studies of storm disasters,differences in storm beach effects,sediment transport under storm conditions and storm-related sedimentology are discussed.The review indicated that there is a lack of domestic studies on storm beach effects based on quantitative measurement and analysis of sediment transport during tropical storms,studies of different storm effects under multi-factors coupling and beach processes under storm conditions.Storm beach effect studies in China are necessary,but deficient;therefore,the integrative field monitoring system should be enhanced as the basis of these studies.In addition,further research regarding beach processes under extreme hydrodynamic conditions are needed.Furthermore,it is necessary to develop beach storm response prediction models.Finally,the development of beach surge protection technologies and their application should be intensified.
