| 摘 要： | 石笋的实测年龄和δ18Ｏ的变化同深海岩芯Ｖ２８-２３８对比相吻合，大于２５万年前生长，１．８万年后停止，属中更新世产物，该区和全球古气候变化同步。同台湾海峡、中国南海古环境相同。δ13Ｃ的变化在δ13Ｏ７-６、５-４、３-２段界期有明显的不同，对温度变化和年代划分亦有参考价值。

| Abstract: | The δ18O change and the age of the stalagmite of the Tiane cave in Ninghua, Fujian Province, are corresponding to that of the V28-238 core of the deep sea. The growth period of the stalagmite began (1.8-25)×104 years ago and belonged to the Middle Pleistocene Epoch. The paleoclimate change in Ninghua area, Fujian, synchronizes with that in the globe and is the same as that in the Taiwan strait and the South China sea. |
