中文摘要：

通过萨拉乌苏河流域下游酒坊台剖面较高精度的主元素氧化物及比值分析,结合测年结果,恢复了流域内晚更新世以来气候环境演化历史,指示了冰期-间冰期旋回在该区有很好的沉积响应。尤其是末次间冰期对应的萨拉乌苏组,各主要指标与深海氧同位素5阶段（MIS5）有明显的对应关系。同时,针对剖面中主元素的地球化学特征,指出古地理特征、气候条件、元素的赋存状态对流域内地球化学特征有明显影响。

英文摘要：

The Jiufangtai section,in the downstream of Salawusu River Valley,has a good record of paleoclimate evolution since the late Pleistocene. On the basis of reliable dating results,we researched on the main elements and verified the relationship between the sediments and glacial-interglacial cycles. Especially,Salawusu Formation during last interglacial has the paleoclimate records which is notable correspond with MIS5. And the indexes,based on the elements,keep some records of regional climate events too. Meanwhile,we analyzed the geochemical characteristics of Jiufangtai section and pointed out that the principal influences on the explanation of the elements include paleogeographic features,the different occurrences of elements and special element properties.
