This data set is composed of tree ring width data of Qilian Mountain region of China in East Asian monsoon region . The tree rings in Qilian mountain contain 52 tree cores, which have 17081 values, the measurement accuracy is 0.01mm, and the tree species is Qilian juniper. The tree ring width was measured by lintab 6 tree ring analyzer, and the cross dating is checked by coffcha program to guarantee that the accuracy of the dating. The experiment analysis was performed in the laboratory of soil structure and minerals, Institute of Geology and Geophysics, Chinese Academy of Sciences. This data has certain significance for the study of paleoclimate in the edge of East Asian monsoon region .
