摘　　要：鉴于风暴作用对淤泥质潮滩-潮沟系统的地貌演变有重要的影响,对海岸工程的安全以及海岸带资源的开发与保护有重要的实用价值,从研究方法、演变特点和动力机制等方面回顾了风暴作用下淤泥质潮滩-潮沟系统地貌演变的研究进展。认为淤长型潮滩风暴剖面的形态特征一般呈“中间冲刷,两端淤积”,但其动力机制研究系统性还不够;盐沼可以较好地削弱风暴,起到固沙效果,但其侧向演变值得进一步关注;风暴作用下潮沟的活动性大大增强,其中潮沟摆动及其岸壁侵蚀机理是亟待解决的科学问题。指出未来应进一步加强现场资料的获取,并通过数值模拟、物理模型试验等手段,加强对风暴作用下潮滩-潮沟系统地貌演变机理的研究。Coastal storm has important impacts on morphological evolution of mud tidal flat-creek system,and related research is of great practical value to the safety of coastal engineering and to the development and protection of coastal zone resources.The research progress of coastal storm impacts on morphological evolution of mud tidal flat-creek system was reviewed in terms of research methods,evolution characteristics and dynamic mechanisms.The storm profile for the accretional mudflats is generally eroding in the middle and depositing at both ends,but the study on its dynamic mechanism is not systematic enough.Salt marshes can effectively weaken storm and stabilize sand,but their lateral evolution deserves more attention.Under the impact of storm,the activity of tidal creeks is greatly enhanced,among which the mechanism of tidal creek shift and the bank erosion is a scientific problem urgently to be solved.In the future,it is necessary to further strengthen the acquisition of field data and strengthen the study on the morphological evolution mechanism of the tidal flat-creek system under the impact of storm by means of numerical simulations and physical experiments.
