本文以宁化县天鹅洞和永定县仙湖洞为代表介绍闽西石灰岩洞穴地质特征，并通过石笋的14C、铀系年代测量等研究成果探讨石笋发育过程的古气候和石笋生长速率。结果表明，闽西石灰岩洞穴发育在70Ma，B．P．，鼎盛时期在12～1MaB．P．间，石笋发育从210ka，B．P．至11ka，B．P．经历5个不同气候期。石笋发育速度不仅受气候期影响，同一时期地方性气候不同的石笋生长速率亦有明显差异。 In this paper, the Swan hole in Ninghua County and Xianhu Cave in Yongding County are introduced to introduce the geological characteristics of limestone caverns in western Fujian Province. The paleoclimate and the growth rate of stalagmite in stalagmite development process are discussed based on the research results of 14C and uranium dating of stalagmite. The results show that limestone caves in western Fujian developed at 70 Ma, B. P. , The heyday of 12 ~ 1MaB. P. Between, stalagmite development from 210ka, B. P. To 11ka, B. P. Experience 5 different climate periods. Stalagmite growth rate is not only affected by the climate, the same period of local climate stalagmite growth rates are also significantly different.
