摘　　要：从古土壤中碳酸钙淀积深度、钙结核中氧同位素组成、磁化率、全铁、地球化学元素等替代性指标方面回顾了国内外对古气候定量化研究的现状,并对研究中存在的一些问题进行了讨论。The current quantitative researches about ancient climate both at home and abroad were reviewed from some proxy indicators of ancient soils,including the depth of calcium carbonate deposition,the oxygen isotope compositions in calcareous concretions,magnetic susceptibility,total iron,geochemical elements and so on,and finally some problems existing in those researches were discussed.

关 键 词：钙质土壤 钙结核 磁化率 全铁 地球化学
