| Abstract: | Using tree rings of Picea schrenkiana sampled from the upper treeline in the headwaters of the rümqi River,21 tree-ring density series were developed,and then the earlywood density(EWD) chronology was established.Analyzing the characteristics of the chronologies and their respond to climate factors,the EWD chronology was found that correlates at 0.651 with the anomaly of maximum mean temperature in July over the period 1959—2006,which explained 42.4% of the variance in the reconstruction(F=33.805,P<0.0001).According to the temperature reconstruction in the headwaters of the rümqi river,the anomaly of mean maximum temperature over the period 1623—2006 was 0.37 ℃.The temperature reconstruction has a good response to the history records,temperature reconstructions from tree-ring and glacial change.The results reveal the common climatic extremes and climate change over Northwest China.Many of these events have had profound impacts on the peoples over the past several centuries,for example the 1640s great drought.Multitaper spectral analysis indicates that there were some low-and high-frequency cycles with the periods of 192 a,29.3 a,6.8 a,4.3 a,4 a,3.7 a,2.3 a and 2.1 a.Abrupt change of temperature occurred in 1645,1665,1726,1807,1833,1855,1878,1929 and 1954. |
