摘要
选取干旱区石羊河流域终端湖猪野泽为研究对象,建立沉积物粒度、地球化学指标与湖泊水位之间的定量关系,将定量重建结果与沉积环境、沉积物指标进行对比验证.结果表明,基于中值粒径、平均粒径、w(总有机碳)及综合多指标定量重建的全新世猪野泽湖泊水位变化,与粒径指标、地球化学指标及沉积环境变化一致.对比亚洲季风和中亚西风带控制地区典型全新世记录发现,猪野泽湖泊水位变化受到亚洲季风模式和中亚西风模式的共同影响.
Lake level changes of the Zhuye terminal lake on the Shiyang River was reconstructed using grain size and geochemical indicators.The reconstruction was compared with the sedimentary environment and indicators.The results showed that lake-level variations were consistent with the grain size index,geochemical index and sedimentary environment.The lake-level changes in Zhuye Lake were strongly influenced by a combined effect of the Asian monsoon and the westerly winds according to a comprehensive analysis for Holocene lake records for the Asian monsoon region and the arid Central Asia.
