黄土高原黄土-古土壤序列古气候代用指标综述

Research on Loess-Paleosol Sequence Paleoclimatic Proxies in Loess Plateau

  • 摘要: 黄土高原黄土-古土壤序列是古气候演化在陆相地层中的反映,已经成为认识第四纪地球气候与环境变化的3个重要信息载体之一,可用来探讨东亚季风气候的形成演化和受控机制、气候突变事件的记录乃至反演我国内陆干旱化历史.稳定同位素、磁化率和孢粉等气候代用指标的地球化学、物理学以及生物学分析为提取黄土-古土壤序列中蕴藏的古气候环境信息提供了新的途径.随着定量重建古气候方法的不断引进,运用替代指标研究的结果的准确度和精度也在不断提高.
    Abstract: Loess-paleosol sequence in Loess Plateau reflects paleoclimatic evolution in continental strata,which has become one of three important information carriers to recognize global climate and environmental changes in Quaternary.It can be used to analyze the mechanisms of the formation and evolution about the East Asian monsoon climate,record climate events and report the inland drought histories in China.Geochemical,physical or biological analysis of climate proxies such as stable isotope,magnetic susceptibility and pollen,provide a new way to extract ancient climate information in the Loess-paleosol sequence.With the introduction of the methods about quantitative reconstruction of paleoclimate,the accuracy and precision of the results become more and more improved.
