摘要
以年代标尺和古气候代用指标的建立为线索 ,总结了国内外近年来对全新世泥炭沉积古气候记录研究取得的最新进展 ,展望了未来泥炭古环境记录研究的前景 ,指出在建立可靠年代标尺和可靠环境代用指标过程中存在的一些急需解决的问题 ,如年代标尺与环境代用指标序列的协调问题 ,提出在泥炭剖面年代标尺建立过程中有必要分析环境代用指标 ,选取合适的组分进行测年。最后 。
The latest advances of paleoclimatic study on Holocene peat sediments are reviewed based on the process of reconstruction of chronology and climatic proxy sequences. The future research of the paleoenvironmental study according to peat records is also prospected. The authors point out some problems which are in dire need of solving for the reliable chronology and environmental proxies.One of the problems is the coordination between the chronology and climatic proxy sequence. The authors emphasize that it is necessary to select suitable component for radiocarbon dating responding to the different paleoclimatic proxies. Finally, the new direction of trace research of the atmospheric environment using Holocene peat sediments is put forward and the key significance of this new study is emphasized.
