A coastal dune, Dongshan (DS) dune in Changle of China's Fujian Province is selected as a research object based on the systematic field investigation. Combined with the environmental index analysis and geological radar images, the dune development history and paleoenvironment significance in the study area since the late Holocene are explored through optically stimulated luminescence (OSL) chronology. Results are shown as follows. (1) Five sedimentary periods and three sedimentary discontinuity in the DS dune can be defined, which reflects that the change of the East Asian monsoon, and the developmental process of DS dune are the result of regional response to the East Asian winter monsoon, and they are well correlated with volcanic activity, winter temperatures of East China and precipitation of summer monsoon at the same time. (2) Meanwhile, DS profile has preserved the sea-level change information of the Fuzhou Basin since nearly 6 ka BP. The widespread thalassocratic periods were recorded clearly in South China at 5.6-2.8 ka BP, 2.8-1.7 ka BP and 1.7-0.8 ka BP, respectively. (3) Artificiality and the mark of human activity are observed in the DS dune, and porcelain shards and conchs have been found in the cultural layer. The development processes of the DS dune accord well with the records of human activities and neolithic cultural sequences in northeast Fujian. The human activities are mainly affected by the natural environment at 5.6-2.8 ka BP and 2.8-1.7 ka BP, respectively. Tang and the Five Dynasties were the recovery stages of social economy in Fujian after 1.7 ka BP.
