| Abstract: | As a type of negative topography in sand land, blowout has always been one of the main research object of aeolian geomorphology. Especially, multi-directions and long-term research has been conducted internationally on basic morphology, development process and dynamic mechanism of coastal sandy blowout. Based on the systematic review of research on coastal sandy blowout, the main progress of research on coastal sandy blowout in morphological evolution, morpho-dynamic process, and research methods was summarized. In consideration of the disadvantages of research on coastal sandy blowout, it was proposed that, at present, the research on coastal sandy blowout in China should strengthen the further research on the evolution mechanism, morphology-material-dynamic process and numerical simulation of different types of blowouts, and attach importance to the influence of blowout on the beach-dune dynamic environment and foredune restoration. |
