Jianping Zhang Houyuan Lu Wanfa Gu Naiqin Wu Kunshu Zhou Yayi Hu Yingjun Xin Can Wang文献传递 晚冰期月亮湖炭屑记录反映的古气候演化 被引量:10 2013年 位于大兴安岭中段的月亮湖地处季风/非季风影响过渡地带,其沉积岩心下部886~546em的炭屑记录揭示了末次冰期晚期到全新世早期(20.9—10.8cal.kaB.P.)的古气候演化历史,反映了东亚季风对研究区气候的影响。研究区炭屑浓度的变化主要由可供燃烧的生物量决定,生长在气候温暖时期的森林草原能够提供更多可供燃烧的生物量。在同一植被类型的条件下,气候寒冷湿润时炭屑浓度低,气候温暖干旱时炭屑浓度高。20.9~18.0cal.kaB.P.炭屑浓度较低,气候寒冷偏干;18.0~15.3cal.kaB.P.炭屑浓度最低,气候寒冷湿润;15_3~14.4cal.kaB.P.炭屑浓度增高,气候开始向温暖的方向发展;14.4—11.8cal.kaB.P.炭屑浓度快速变化,气候也经历了一系列的快速变化;11.8—10.8cal.kaB.P.炭屑浓度总体较高,气候温暖湿润。〈50μm的炭屑浓度指示了区域火演化的历史,〉50μm的炭屑则反映了当地野火发生的状况。 伍婧 刘强关键词:古气候 Holocene cyclic climatic variations and the role of the Pacific Ocean as recorded in varved sediments from northeastern China We present an n-alkane and compound-specific carbon isotope record of the past 9 ka from the annually laminate...

Wuhui Duan Bahadur Singh Kotlia Ming Tan文献传递 晚冰期以来月亮湖生物硅含量变化的古气候意义 被引量:3 2012年 根据大兴安岭中段小型火山口湖月亮湖沉积序列生物硅含量(BSi)替代性指标的分析,结合总有机碳(TOC)、总氮(TN)含量等分析结果,重建了该区末次冰期晚期(21cal.kaBP)以来的高分辨率古气候演化序列。研究结果表明:月亮湖生物硅含量变化范围为0.52%~15.88%,其中末次冰期晚期(21~14cal.kaBP)生物硅含量比较低、变化不显著,反映了冷干的气候条件以及低的湖泊初级生产力环境;自14cal.kaBP开始,生物硅含量开始明显增加并出现频繁波动,特别是末次冰消期向全新世转换期间,冷暖波动十分频繁;全新世期间生物硅含量也存在多次波动,可进一步划分出10.8~7.9cal.kaBP凉干期、7.9~6.9cal.kaBP暖湿期、6.9~3.9cal.kaBP凉干期、3.9~3.4cal.kaBP暖湿期、3.4~2.4cal.kaBP凉干期、2.4~0.6cal.kaBP波动中的变凉变干期以及0.6cal.kaBP以来的暖干期等气候阶段;全新世期间一些快速的冷干事件出现在10.2、9.8、9.4、8.2、5.2、2.9、0.9、0.6cal.kaBP左右,反映了夏季风减弱事件。 王利贤 刘强 游海涛关键词:生物硅 晚冰期 全新世 古气候
