In extremely arid area,the clear sedimentary veins of Tamarix cone can be used as a geologic counting method and provide lots of information on climate and environment for hundreds of years. Based on a comprehensive determination of the sedimentary age of the Tamarix cone in the study area through various dating methods, experimental analysis showed the content of delta~(18)O in the sedimentary age of the Tamarix cone. SPSS software was used for correlation analysis and regression analysis to reconstruct the climate change sequence during the past 200 years in Andier region. The results of the study showed that the most significant effect on the change of delta~(18)O was the sunshine hours in February and the average temperature in November. Since 1792,Andier's climate had totally developed from cold and dry to warm and wet. Among them,the periods of 1792 ~ 1828 and 1850 ~ 1917 were cold and dry,and the periods of 1829 ~ 1849 and 1918-2010 were warm and wet.
