第四纪古环境重建是近代学术热点之一,用于古环境重建的资源很多,但能够进行高分辨率定年的较少.喀斯特沉积物蕴含有高分辨率的古环境信息,已经被广泛的应用于古环境重建,并取得了较多成果,但目前对沉积物的形成过程和环境响应研究较为薄弱.沉积矿物在形成和成岩的过程中伴随的碳氧同位素变化和其它物质迁移影响古环境重建的准确性,为降低这些过程对古气候重建的影响,需要更多的环境监测来实现.

The palaeo-environmental reconstruction in quaternary period is one of the hot spots in modem science. Many natural resources arc used in the palaeo-environmental reconstruction; however, few of them can be applied to the high resolution for years. Karst sediments contain too much palaeo-environmental information for high resolution, so they have been widely used in palaeo-environmental reconstnlction with more achievements, but it is some weak to do research on the forming process of sediments and environmental response. In the forming process of sedimentary minerals and diagenesis and in other materials movement, carbon oxygen isotopes changes affect the accuracy of the palaeo-environmental reconstruction. Therefore, too much environmental monitoring is required to reduce the affection of processes on the palaeo-environmental reconstruction.
