Based on the Sabina przewalskii samples obtained in the eastern part of Qilian Mountain, west of China, a standardized tree-ring chronology was established. The correlation analysis was carried out between the tree-ring index and the temperature as well as precipitation at Wushaoling Meteorology Station, which is 70 km away from the sampling site. The results showed that the tree-ring index significantly correlates with the precipitation of March and April, with a coefficient of 0.525. The precipitation of March and April in the study area were reconstructed for the past 300 years. It can be seen that the climate has become wetter in the past 300 years. The statistics confirm that the reconstruction series is reliable.
