通过桂林灌阳响水岩 1号石笋的测年和O、C同位素的详细研究 ,得出了桂林地区 4万a来高分辨率的古气候变化的连续记录 ,并揭示了由末次冰期向全新世的突变过程和 3次与Heinrich事件 (H1 、H2 、H3)对应的气候突变事件。在此基础上 ,通过与GISP2冰芯记录、古海水表面温度记录、深海海底生物的O同位素记录和苏禄海沉积物O同位素记录的对比 ,认为我国古季风环流变化的直接动力机制是全球冰量的变化。 Based on the dating of the stalagmite No.1 in Xiangshuiyan, Guilin and the detailed study of O and C isotopes, the continuous record of paleoclimatic change with high resolution of 40,000 a in Guilin area was obtained, World mutation process and three climate abrupt events corresponding to Heinrich events (H1, H2, H3). On the basis of this, we can conclude that the direct dynamic mechanism of the circulation of the ancient monsoon circulation in China is the global ice with the comparison of ice core records of GISP2, ancient sea water surface temperature records, O isotope records of deep-sea marine organisms and O-isotopic records of Sulu Sea sediments. The amount of change.
