洞穴石笋古温度研究进展及其可信度探讨

Review of the Progress of Study on Paleotemperature and Discussion of the Paleotemperature's Reliability of Stalagmites in Cave

本文回顾了深海氧同位素曲线成功地反映了古温度变化的原因，分析了陆相环境古温度定量研究的困所在．洞穴钟乳石古温度研究经历了定性、半定量和定量三个发展阶段．最后对古温度定量研究中的三个影响因素（水的δ１８Ｏ，石笋生长速率及同位素分析精度）进行了探讨．

The reason why δ18O Curve of deep Sea sediments and some living thing's Crusts successfully reflects the change of paleotemperature is reviewed in this paper.Then, thedifficulty of study on paleotemperature under the environment of land is discussed. The progress of Paleotemperature of spele-othems in Cave can be divided in to 3 stages:determining property, semi - determining amounts,determining amounts. At last, theauthor discuss the three factors infecting paleotemperature's reliability of speleothems in cave.
