| 摘 要： | 自20世纪80年代以来，国外对海岸沙丘的研究已从主要对其地貌形态的研究转向海岸海丘与海岸变迁尤其是全球变化关系的研究上，海岸沙丘形成与演化的研究倍受关注，进行了大量研究并取得了一定的研究成果。这里介绍了国外在海岸沙丘形成与演化研究方面的主要进展及其成果，并以此探讨了国内今后开展海岸沙丘形成与演化研究的主要方向与问题。

| Abstract: | Research of coastal dunes has been paid a great attention to since 1980 in foreign countries and now is one of the most important international research regions. During this period, the research direction of coastal dunes was changed from mainly in geomorphic aspects of coastal dunes into the formation and evolution aspects, because of the internal relationship between the formation and evolution of coastal dunes and global changes. This paper reviews the research processes of the formation and evolution of coastal dunes in some foreign countries, and introduces the main developments or achievements in the research of formation and evolution of coastal dunes since 1980. This paper clearly analyzes the main research developments in the conditions and mechanism of formation of coastal dunes and in the processes and model of coastal dune evolution. In recent years, the main research progresses are that the new theory of geomorphic dynamic system between beach and coastal dunes has been applied to the formation study of coastal dunes in foreign countries since 1980 and the new explanation of evolution mechanism has been given. Based on above, it can be found that there are some differences in the researches on the formation and evolution of coastal dunes between China and foreign countries. Learning from abroad, we should do more in the research on the formation and evolution of coastal dunes. At last, the main research directions in near future are suggested. First, we should use new systematic theory to study the formation of coastal dunes. Second, we should totally study the processes of coastal dune evolution all over the coasts in China and make clear the mechanism of coastal dune evolution. Third, the prediction of the development trend of coastal dunes under the influence of global changes in the future should be studied on the basis of understanding of the relationship between coastal dune evolution and global changes. |
