LIU Qi-ming, WANG Shi-jie, OUYANG Zi-yuan. THE STALAGMITE MICROBANDING IN RESEARCH OF HIGH RESOLUTION CLIMATIC-ENVIRONMENTAL CHANGES[J]. Advances in Earth Science, 2002, 17(3): 396-401.

It’s one of the most important task to reconstruct high resolution climatic-environmental changes in the last 2 ka of global change. The same as other natural materials (loess、ice-core、tree rings、sea deposits), spleothems are important repositories of palaeoclimatic and palaeoenvironmental information. On the basis of sedimentary characteristics and bedding-structure, stalagmite microbanding are ideal data in research of high resolution climatic-environmental changes, able to provide climate information with an annual resolutions and much longer time span compared to tree rings. Two aspects of annual banding of stalagmite have been reported, the luminescent microbanding observed under a fluoromicroscope and the lamina which is visible to the naked eye. It involves same climatic-environmental information, such as precipitation, temperature, soil and vegetation. In this paper,  the authors analyze the causation、category and influencing factor of microbanding grey and microbanding thickness in detail, review and synthesize the recent advances in stalagmite microbanding research of high resolution climatic-environmental changes, and also point out the existing problems and forecast the trends.
