摘　　要：古海水温度不仅是古海洋研究中的重要参数,而且对研究地质历史时期的全球气候变化具有重要的意义。长期以来,重建古海水温度一直是研究重大地质突变期生物与环境事件的前沿科学问题,因此其重建理论和方法也备受关注。目前,古海水温度重建方法主要包括古生物学指标和地球化学指标两大类。古生物学指标从最初仅能够定性分析的标志种及其组合等方法,发展到能够定量分析的转换函数统计法;地球化学指标从传统的氧同位素过渡到微量元素、生物标志化合物、耦合同位素Δ47等指标。对目前古海水温度重建方法进行了系统介绍,特别是从方法的原理、适用范围及优缺点等方面对近年来新发展的指标(如:Uk′37、TEX86、Δ47等)进行了评述,并对将来古海水温度重建方法的发展作了展望。Paleo-seawater temperature,as one of the most significant parameter in paleooceanography,plays a key role in the studies on global climate evolution of geological history.It has been a frontier scientific question in the geoscience researches to reconstruct paleo-seawater temperature.Hence,the theories and methods of paleo-seawater temperature proxies have attracted great attention.Currently,the methods of paleo-temperature reconstruction mainly include paleontology proxies and geochemistry proxies.The paleontology proxies have developed from qualitative methods such as index species and their combination,to quantitative faunal transfer functions methods.Furthermore,geochemistry indexes have improved from traditional stable isotopeδ18 O and trace elements to the latest indexes,including biomarkers and clumped isotopes.This paper elucidates these methods systematically,including their geochemical principles,analysis and testing methods,applications,advantages and disadvantages,especially for the details of the latest proxies（such as Uk′37,TEX86 andΔ47）.The paper also previews the prospect of paleo-seawater temperature proxies.
