距今5万年～1万年间浙江临安瑞晶洞穴石笋古温度记录

Paleotemperature Record of Stalagmite from Ruijing Cave, Lin' an County, Zhejiang Province,during the Period from 50000 to 10000 yrs B. P

用稳定同位素地球化学古温度测定方法，对浙江省临安县瑞晶洞穴石笋进行了古温度研究，结果表明该地区在距今５万年～１万年间古温度有三次较明显的周期变化，最高温度为１４．９℃，最低温度为６．６℃，最大温差为８℃左右，平均温差为３～５℃．用该方法测定的古温度研究结果与其它本法的古气候研究结果相一致．

The paleotemperature of stalagmite,collected from Ruijing Cave, Lin'an County,Zhejiang Province,wasdetermined by using a stable-isotope geochemical method. The results show that during the period from50 000 to 10 000 yrs B. P.,the paleotemperature of study area had three-time obvious cyclic changes,andthat the highest temperature was 14. 9℃,the lowest 6. 6℃,the maximum temperature difference about 8℃,and the average temperature difference ranged from 3 to 5℃. The results are in keeping with the research results on paleoclimate obtained by using other methods.
