应用同位素地球化学方法，并以现代溶岩水的δ¹⁸O_w，代替石笋生长时期原生包体水的δ¹⁸O_w，根据O'Neil方程，计算了福建宁化天鹅洞内第四纪碳酸盐堆积物的古温度。结果表明，温度计算偏差在±0.5 ℃左右。在与全球深海氧同位素曲线对比后，指出该地区大约在210~18 ka BP，武木亚间冰期的起始时间(氧同位素期3/4阶界限)估计在65 ka BP。结果表明，福建宁化地区晚第四纪古气候环境没有形成冰川的条件，但明显受到全球气温变化的控制。

Applying the isotopic dating and temperature-probing techniques, the isotopic paleotemperature of the speleothems evolutions from the Tian-e Cave, Ninghua county of Fujian Province, is obtained based on the O'Neil's Equation. The temperature evolutional curve is compared with that of the global O-isotopic curve of deep-sea foraminifera, which shows that: in this area there had obviously experienced five times of large temperature variation processes from about 210 ka to 18 ka BP, which correspond to the 6 th, the 5 th, the 4 th, the 3 rd and the 2 th stage respectively in the oxygen isotopic periodity. It is estimated that the Riss glacial ended up at about 155 ka BP, and the Würm subinterglacial began at about 65 ka BP.Results argue that there was no conditions to form glacier in this area under the Late Quaternary paleoclimate environments, which was influenced by the global temperature variations substantially.
