用１４Ｃ测年技术和稳定同位素地球化学古温度方法，对浙江省临安瑞晶洞穴的石笋进行了１４Ｃ的测年和碳、氢、氧同位素测试，获得５～１万年间杭州地区古气候演化记录、该记录表明，在５～１万年间有三次较明显的周期性古温度变化，最高温度为１４．９℃，最低温度为６．６℃，最大温差为８℃左右，平均温差３～５℃。这段时期正处在大理冰期后期，但大理冰期并不是一个持续的低温阶段，它至少有３次温度波动。与我们获得的石笋同位素古温度相一致。另外，我们将５～１万年间杭州地区古气候变化与同期东南沿海的海平面变化进行了对比，在时间上也较为吻合，也就是温度上升、海平面也上升，温度下降、海平面也随之下降
The 14C dating and carbon isotopic dating of the stalagmites in Ruijing caves in Lin’an, Zhejiang province were conducted using 14C dating techniques and stable isotope geochemical parabolic temperature methods. The paleoclimatic evolution records of Hangzhou during 5 ~ 10,000 years were obtained , The record shows that in the 5 to 1 million years there are three obvious periodic paleo-temperature changes, the maximum temperature of 14.9 ℃, the minimum temperature of 6.6 ℃, the maximum temperature difference of about 8 ℃, the average temperature difference of 3 to 5 ℃. This period is in the late Dali ice age, but the Dali ice age is not a sustained low temperature phase, it has at least three temperature fluctuations. It is consistent with the ancient isotopes of stalagmites we obtained. In addition, we compare the paleoclimatic change in Hangzhou with the sea level in the southeast coast of China in the 5 to 10,000 years with the sea level in the southeast coast in the same period, which is also in accord with the time, that is, the temperature rises, the sea level also rises, the temperature decreases, and the sea level changes Drop down
