摘　　要：在各种湖泊的沉积物研究中,自生碳酸盐氧碳同位素指标得到了广泛的应用。通过氧碳同位素分析实验,可以利用湖泊次生碳酸盐氧碳同位素恢复湖泊的古气候、古盐度和古温度。在样品分析测试时也应注意外源碳酸盐岩与湖泊自生生碳酸盐岩的区分。In the study of sediments in various lakes,the oxygen and carbon Isotope index of authigenic carbonate has been widely used.Through the oxygen and carbon isotope analysis experiments,the paleo-climate,paleo-salinity and paleotemperature of the lake can be restored by using the carbon and carbon isotope of the secondary carbonate of the lake.At the time of sample analysis and testing,attention should also be paid to the distinction between exogenous carbonate rocks and Lacustrine Authigenic carbonate rocks.
