海岸风沙地貌台风响应研究的现状与趋势

 基于台风对海岸风沙地貌影响研究发展的简要回顾，概括了国外近期在海岸沙丘风暴响应的差异性及其机理、风暴响应沉积特征以及新技术应用等方面的主要进展，认为国内适时开展台风对海岸风沙地貌形态与沉积特征影响研究十分必要，建议以华南为研究区域，通过对台风前后不同类型海岸沙丘形态变化的高精度测量、非台风季风沙运动过程的定位观测以及沙丘沉积物的系统采样分析等，研究华南海岸风沙地貌形态和沉积变化与台风间的相互联系，探究台风对华南海岸风沙地貌的作用规律，建立华南海岸风沙地貌的台风响应模式。

Review on the Typhoon Effect on Coastal Aeolian Landforms

Based on the research development review of typhoon effect on coastal aeolian landforms, the main abroad research developments in recent years are summarized, which included the research on the difference and its mechanism of typhoon effect on coastal aeolian dunes, the deposit characteristics of typhoon effect on coastal aeolian dunes, and the new research techniques and methods used in the research on the typhoon effect on coastal aeolian dunes. In accordance with the short knowledge of typhoon effect on coastal aeolian landforms in China, it is essential to carry out the research on the typhoon effect on coastal aeolian landforms in China. We suggest to take south China coasts as research region which is seriously suffered by typhoon, rely on the pre-and post-typhoon high-precision surveying of shape change of different type coastal aeolian landforms, fix position observation of wind-sand processes in the season of non-typhoon time and systematic sampling analysis of aeolian deposit sediments over coastal dunes, research the difference of typhoon effect on the shape and deposit sediment of different coastal aeolian landforms in the near future, in which the relationship between the typhoon and the change of shape and deposit sediment of coastal aeolian landforms would be quantitative analyzed, the basic rule of typhoon effect of coastal aeolian landforms in south China would be explored and the models of typhoon effect of coastal aeolian landforms in south China will be established.
