摘      要：Coastal dunes are a common geomorphic type in sandy coastal *** are a record of the coupled evolutionary processes of the wind and ocean *** coastal dune fields have developed on the east coast of Fujian China and now occur as widespread typical coastal aeolian sand landforms on the Liuao Peninsula,Gulei Peninsula and Dongshan Island,but it is difficult to evaluate the dynamic geomorphologic process of sandy coast due to the lack of systematic and accurate chronological *** this study,we selected the Hutoushan(HTS)aeolian dune on the Liuao Peninsula as the research *** dating and grain-size analysis were applied to sand samples from the aeolian sequence of a profile of the HTS *** results show that the ages of seven samples of this profile were in the range of 37.8–0.19 ka from 4.0 to 0.2 m *** correspond to the Marine Isotope Stage 3(MIS3),abrupt climatic change events of 4.2 and 1.1 ka and the Little Ice Age(LIA),*** samples displayed evidence of a longer-term climate trend in this *** period of formation of this coastal aeolian dune corresponds to a cold and arid climate associated with the East Asia Winter Monsoon(EAWM).Periods of dune fixation and rubification are evidence of a hot and humid *** and stabilization of the aeolian dune is an important characteristic of the coastal evolution in South China since the late Pleistocene.
