气候特征是冰期和相对温暖的间冰期交替发生。湖泊沉积物以其连续性好、敏感性强和高分辨率的特点,在恢复和重塑各种短时间尺度(千年、百年、十年)的气候和环境演化序列上,具有其它自然历史记录无法替代性。本文主要研究沉积物粒度的环境含义,古气候特征,尘暴,构造运动等环境信息很好的保存在湖泊沉积物粒度上。因此,本文通过对湖泊沉积物粒度的研究进而推断当时的环境特征。
Climatic characteristics are that the glacial period and the relatively warm inter-glacial period occur alternately. Lake sediments, with their good continuity, high sensitivity and high resolution, have other natural historical records in the sequence of climate and environmental evolution for restoring and remolding various short-term scales (years, centuries and ten years) Can not be replaced. This paper mainly studies the environmental meaning of sediment grain size, paleoclimate characteristics, dust storms, tectonic movements and other environmental information well preserved in lake sediment grain size. Therefore, in this paper, through the study of lake sediment grain size and then infer the environmental characteristics.
