基于国内外利用湖泊沉积物研究洪水事件、重建洪水序列的研究成果,综合整理了湖泊沉积物中判识洪水事件的常用沉积物指标,评述了这些指标在洪水层中的变化特征.在此基础上,指出了利用湖泊沉积物研究洪水事件进而重建洪水序列存在的影响因素以及研究要点,最后对该领域未来的研究方向进行了展望.
Base on the research achievements about flood events using lake sediments in the domestic and oversea, the indexes of lake sediments and their change features on flood stratigraphies in lakes sediments are synthesized and sorted. On this basis, the paper discusses the impact factors and the key points of identifying flood events in lake sediments and reconstructing the flood histories. The directions of further research are also provided.
