摘　　要：罗布泊地区的红柳沙包,具有清晰的沉积纹层,与树木年轮一样,具有准确的计年和储存环境信息的功能。通过对罗布泊典型红柳沙包中沙层沉积厚度、落叶阳离子含量、C/N、δ13C、δD、δ18O等序列中记录的环境代用指标极端值与极端气候事件的相关性分析发现,环境代用指标极端值与极端气候事件之间有很好的对应关系。依此分析了近160 a罗布泊地区极端气候事件的发生规律和影响因素。Some veracious dating and environmental information was recorded in the laminas of the Tamarix sp.dunes in the Lop Nur Lake region,and the laminas are as good as tree rings for dating and revealing the ancient environmental conditions.In this paper,the correlations among the proxy environmental indicators and the extreme climate events,recorded by the C/N,δ13C,δD,δ18O,etc.,were analyzed.The results revealed that there were the good correlations among the proxy environmental indicators and the extreme climate events in the Lop Nur Lake region.On which the extreme climate events and their affecting factors in the Lop Nur Lake region were lucubrated..
