From the analysis of the magnetic susceptibility,TOC,TN,pigment,organic car-bon isotope ,HI,saturated hydrocarbon and 14C dating etc. of the sediment samples from coresof two boreholes in the Taihu lake,a knowledge of the evolution of paleoenvironment of thelake during the last 14ka is achieved. The results show that the lake has undergone the fol-lowing stages .. The Lake was at a low level ,or even became exposed during 14.3-13.3kaBP,reflecting an arid climate. There existed a transitional stage during 13.3-12.4kaBP,the climate being slightly warm and wet. There are indications of a cold and dry climate around 11.5kaBP,probably corresponding to the Younger Drays event ,comparable with other areas in east China.

本文根据东西太湖短柱岩芯的沉积物的物理、化学、生物指标的综合分析，讨论了该区距今14ka来的古气候变化过程，结果表明14.3-13.3kaBP，太湖水位低，环境指标甚至表现为暴露特征，反映了气候干旱：13.3-12.4kaBP，为偏暖湿的过渡阶段；该孔柱270-280cm(11.5kaBP左右)各类指标均明显更映冷干特征，可能是Younger Drays事件的记录，与我国东部其它地区有可比性；约10.9-10kaBP，这一时期是整个研究时段内一个较显著的温暖期。
