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
