摘要:

选取福建长乐典型海岸沙丘进行研究,在光释光(OSL)年代学基础上,结合环境代用指标分析和地质雷达图像,探讨研究区晚全新世以来沙丘发育历史及其古环境意义。结果显示:① 东山(DS)沙丘发育过程主要存在5个沉积期和3个沉积间断。主要反映了东亚季风强度变化,是东亚冬季风的区域响应结果。同时与火山活动、中国东部冬半年气温、夏季风降水具有良好对应关系;② DS剖面保存了近6 ka以来福州盆地海平面变化信息。清晰记录了存在于闽粤台地区的大范围的高海面期,分别是5.6~2.8 ka BP、2.8~1.7 ka BP、1.7~0.8 ka BP,其中1.7~0.8 ka BP阶段最为明显。③ DS沙丘发育过程与闽东北区域人类活动记录以及新石器文化序列具有良好对应关系。5.6~2.8 ka BP、2.8~1.7 ka BP阶段的人类活动主要受到自然环境影响。~1.7 ka BP之后,唐代至五代是福建社会经济的复苏阶段。

Abstract:

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.
