| 摘 要： | 依据ＴＬ和＾１４Ｃ测年数据及各项环境指标分析，对九江－红光澎泽一带沙册剖面进行了研究和对比，讨论了１４７ｋａＢ．Ｐ．至晚冰期的年代地层序列和古气候环境，同时对沙山在、古湖沼形机制进行了深入探讨。该区沙山地貌并非新的构造运动所致，属差异侵蚀作用的结果，泥炭层由风积地区沙丘间湖沼沉积形成。

| Abstract: | According to data of TL and 14 C dating and the analysis of environmental indexes,the sand hill profiles from Jiujiang to Hongguang in Pengze are studied,and the chronostratigraphic succession and its palaeoclimatic environmental changes are discussed.This paper,in detail,deals with the cause of formation of sand hill and formation mechanism of palaeolimnology.The sand dune landscape was not caused by tectonic movement,but by wind and different erosion,and the peat layers were formed in limnological environment in the wind accumulating dune area. |

| Keywords: | late Pleistocene chronostratigraphic succession palaeomonsoon the cause of formation of sand hill paleolimnology |
