摘　　要：依据 TL和 1 4 C测年数据及各项环境指标分析 ,对九江—红光澎泽一带沙山剖面进行了研究和对比 ,讨论了 147ka B.P.至晚冰期的年代地层序列和古气候环境 ,同时对沙山成因、古湖沼形成机制进行了深入探讨。该区沙山地貌并非新构造运动所致 ,属差异侵蚀作用的结果 。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.
