摘要： 洞穴化学沉积物由于其特有的微层结构及其内的稳定氧、碳同位素和微量元素所蕴含的古气候与古生态环境信息 ,并且具有分布广、时间长、信息保存完整等特点 ,因此 ,它是研究地球环境变化极好的自然环境历史档案。几十年来 ,国内外这一领域的研究工作有了长足的发展 ,并已经取得了很大的成就 ,本文分别从氧同位素对气候变化的反映、碳同位素应用于重建地表植被生态环境以及石笋微层和微量元素的高分辨率气候环境指示意义几个方面对此作了较为综合的论述 ,同时 ,对这一领域现今所存在的问题及未来的发展趋势 ,也提出了一些自己的看法。

Abstract: It’s one of the important task to reconstruct Paleoclimatic and Paleoecological Paleoenvironmental changes of global change. Based on the microbanding structure, stable oxygen carbon isotope and trace elements, like other natural materials (loess?ice core?tree rings?sea deposits) , Speleothems are important repositories of Paleoclimatic and Paleoecological Paleoenvironmental data. In recent decades, the study of the paleoclimatic records and paleoecological paleoenvironmental meanings of speleothems achieved appreciable progress. The stable oxygen isotopic sequences of speleothems can give information about precipitation and temperature. The history of changing vegetation can be traced by the stable carbon isotopic sequences of speleothems. And much high resolution climatic environment information, such as precipitation, temperature, soil and vegetation, is involved in microbanding type and trace elements character of stalagmite. This paper is intended to review and synthesize the recent advances. It also points out the existing problems and forecasts the developing trends toward.

Key words: microbanding of stalagmite, speleothems, stable carbon isotope, stable oxygen isotope, trace elements
