根据南京汤山石笋高分辨率氧－碳同位素分析结果，讨论了 ５０～４０ ｋａＢＰ期间 ４个 Ｄａｎｓｇａａｒｄ－Ｏｅｓｃｈｇｅｒ冷暖旋回的洞穴温度和地表植被的快速响应过程．研究发现，Ｄ－Ｏ暖事件时Ｃ３型植被丰度降低，指示了大气有效降水量的减少．石笋氧同位素曲线与格陵兰冰芯对比表明，东亚季风气候在数十年至百年尺度上与高纬极地气候变化基本一致，但石笋对冰漂碎屑事件Ｈ５标定的年龄比格陵兰冰芯提前 ２０ ｋａ，由于定年方法不同，目前尚难确定两者气候事件的相位问题．
According to the results of high resolution oxygen-carbon isotope analysis of Tangshan bamboo shoots in Nanjing, the rapid response of four Dansgaard-Oeschger cycles of cold and warm cycles to surface vegetation was discussed during 50-40 ka BP. The study found that the C-type vegetation abundance decreased during the D-O warm event, indicating a decrease in the effective precipitation of the atmosphere. The correlation between stalagmite oxygen isotope curve and Greenland ice core shows that the East Asian monsoon climate is basically consistent with the climatic change in the high latitudes over the decades or centuries but the age of stalagmite H5 calibration is 20 ka earlier than that of the Greenland ice core. Due to the different dating methods, it is difficult to determine the phase of the climatic events.
