| Abstract: | In this paper, the series of annual precipitation of 526 years in the Northern of Xinjiang is reconstructed from tree rings, and reliability of the reconstructed precipitation series is verified by the istorical precipitation records, historical runoff records, and data of advancing and retreating of glacier. Then, periodicity of reconstructed precipitation series, trends of changing dry, about changing phenomenon and amplitudes of dry and wet are analysed. We find that little Ice Age begins at 1544 in the Northern of Xinjiang, calculate the anomalous percentages to mean precipitition of 526 years within the periods of advancing and retreating of glacier in little Ice Age, and the correlative features between precipitation and temperature in glacier advancing periods. |
