摘　　要：洞穴石笋因分布广、可精确测年、δ18O信号可进行区域对比等优势逐渐成为重要的陆相地质载体.然而,由于量化研究不足,δ18O气候环境意义解译尚处于经验化阶段,特别是亚洲季风区石笋δ18O指标解释存在诸多争议.本文试通过总结已有石笋δ18O、δ13C、微量元素、年层厚度等指标量化研究成果,石笋生长机理模拟实验及相关技术方法,分析其存在问题.结合其它地质材料量化方法,从现代器测资料校准、多指标开发、集成树轮材料等方面提出加强现代监测,促进机理研究,定量认识现代洞穴石笋年～季节尺度沉积旋回与洞穴环境关系,建立量化经验模型,以发挥石笋年代学优势,推动区域或全球对比.The cave deposits, especially the stalagmites, are widely distributed and precisely dated terrestrial archives for paleoclimate studies, the stable oxygen isotope sequences from which were believed to duplicate well between spatially-seperated caves. Nevertheless, climatic interpretation of oxygen isotope from the stalagmites, particularly in the Asian monsoon regions, has been challenged due to insufficient quantitative studies. Thus, previous investigations on quantitative studies of speleothem indicators, i.e. δ18O, δ13C, trace element, layer thickness and growth dynamics are summarized in this issues are tentatively put forward involving calibration paper. Compared with other geologic records, some urgent with monitoring data, multi-proxy studies and combination with the regional tree-ring data. The aim for this paper is stalagmite proxies and climate, and promote the regional to further understand the quantitative relationship between and global comparison with the speleothem records.
