Reconstruction data of paleoclimate in Qilian Mountains in East Asian monsoon region

Reconstruction data of paleoclimate in Qilian Mountains in East Asian monsoon region


Based on the changes of tree ring stable oxygen isotope ratio Since 1750 established in Qilian mountain area, based on the negative correlation between tree ring oxygen isotope ratio and summer drought index, the linear correlation equation between tree ring oxygen isotope and drought index is established, and the quantitative reconstruction of drought index from 1750 to 2016 is preliminarily completed. This result is helpful to understand the characteristics of regional dry and wet change from interannual to interdecadal scale. At the same time, it can also compare and study the impact of global change caused by human activities on regional hydrology and climate since the industrial revolution. It is of certain significance in revealing the mechanism of regional dry and wet change and distinguishing the impact of human activities and natural variability on regional climate.
