高原泥炭记录揭示的全新世季风快速变化

EVIDENCE FOR ABRUPT CHANGES OF THE ASIAN MONSOON DURING THE HOLOCENE: FROM THE PEAT RECORDS OF TIBETAN PLATEAU

  • 摘要: 利用青藏高原东北缘的泥炭沉积记录,重建了该地区全新世冬、夏季风快速波动历史,清晰地识别出9次可与北大西洋浮冰碎屑事件及低纬海面降温事件相对比的气候干冷事件。总有机碳含量频谱分析揭示的1 428、512、255、217 a气候准周期,表明中纬度地区百年至千年尺度气候韵律的存在,全新世气候快速变化具有全球性。

     

    Abstract: Based on the proxies of peat such as TOC, grey scale and ash content, we reconstruct the evolution history of the Asian monsoon during the Holocene. Nine cold and dry events which can be correlated to both ice rafting events recorded in high latitude North Atlantic Ocean sediment cores and cooling events in the low latitude SST are recognized. Spectral analysis of the TOC data indicates that there exists series of periodicities of 1.428 ka,0.512 ka,0.255 ka and 0.217 ka.This further confirms the existence of centennial-millennial scale climatic rhythm in mid-latitude areas, reflecting the global significance of the rapid changes of climate during the Holocene.
