用稳定同位素地球化学古温度测定方法对杭州临安瑞晶洞穴石笋的同位素古温度进行了研究，获得了距今（5～1）×104a间该区的古气候演化记录，并与杭州湾海平面变化曲线进行了对比。
The isotope paleotropical temperature of stalagmite of Ruijing caves in Lin’an, Hangzhou was studied by means of stable isotope geochemical palaeoephrology. Paleoclimate evolution records of this area dating from (5 ~ 1) × 104a were obtained and compared with the sea level of Hangzhou Bay The curve is compared.
