利用采自和布克塞尔铁布克山二号沟的西伯利亚落叶松树轮样本,研制出树轮最大密度年表(MXD)和年轮宽度年表(TRW),分析了其年表特征和气候响应特点。结果表明,该样点的落叶松树轮最大密度年表与和布克塞尔气象站5-8月份平均温度和平均最高温度度均具有很好的正相关关系,最高单相关系数为0.660。用铁布克山二号沟的最大密度差值年表序列,可较好地重建和布克塞尔地区1795-2007年来春夏季平均最高温度距平,47 a重建值对实测值的解释方差达43.5%,且方程稳定。重建结果揭示,在和布克赛尔地区,20世纪平均最高温度距平要高于20世纪以前的平均最高温度距平,20世纪前中期平均最高温度距平出现了明显的上升,并且在重建的时段的末期,5-8月份平均最高温度距平表现出上升趋势。
Using the Siberian Larch tree sample collected from the Tiberium Mountain in No.2 Block of Busker, a tree-ring maximum density chronology (MXD) and annual ring width chronology (TRW) were developed. Climate response characteristics. The results showed that there was a good positive correlation between the maximum density chronological table of Larch tree wheel and the average temperature and average maximum temperature of May - August in Buxcel Weather Station with the highest single correlation coefficient of 0.660. Using the chronological series of the maximum density difference of the Tiebu Buk Shan No. 2 ditch, the average maximum temperature anomaly in the spring and summer of 1789-2007 in the Bouxel region can be well reconstructed and the interpretation variance of the observed value of 47 a reconstructed value Reaching 43.5%, and the equation is stable. The reconstructed results reveal that in Hexbu-Purcell area, the average maximum temperature anomalies in the 20th century were higher than the average maximum temperature anomalies of the 20th century, and the mean maximum temperature anomalies in the middle and early 20th century increased significantly. The average maximum temperature anomalies in May-August showed an upward trend.
