通过巴里坤湖钻孔岩芯沉积相分析、年代学测定、粒度分析、碳酸盐及其稳定同位素测定、孢粉分析等综合研究，建立了巴里坤湖沉积岩芯剖面十五万年来的时间序列、湖水位变化的古水文演化序列，分辨出十五万年来经历的高湖面阶段和低湖面阶段。低湖面阶段对应于冰期阶段，在冰期时，降水主要积累于山地，进入湖泊的水量较少，湖水位降低；高湖面阶段对应于间冰期的到来，山地冰川融化，湖水位迅速上升，但很快达到新的平衡，水位保持稳定。 Through the comprehensive analysis of sedimentary facies analysis, geochronology, particle size analysis, carbonate and its stable isotope analysis and sporopollen analysis in borehole of Barkol Lake, a time series of 150,000 years has been established for sedimentary core section of Barkol Lake. , The change of the lake water level paleo-hydrological series, to distinguish the 150-year experience of the high lake stage and the low lake stage. During the glacial period, precipitation mainly accumulates in the mountainous areas, with less water entering the lake and lower lake water level. In the high lake stage, corresponding to the arrival of the interglacial period, mountain glaciers melt and the lake level rises rapidly, but As soon as the new balance is reached, the water level remains stable.
