摘要:

根据采自天山北坡中部呼图壁河流域6个采点的树木年轮样本,研制出该流域的树木年轮年表。通过相关普查发现,树轮差值年表与春季(5—6月)平均最高气温存在显著的负相关,最高单相关系数为-0.505,且具有明确的树木生理学意义。用喀音萨依(t),喀音萨依(t+1)和希热克久热特(t+1)3个树轮差值年表序列可较好地重建呼图壁河流域313 a来该时段平均最高气温变化,交叉检验表明重建结果稳定可靠。呼图壁河流域313 a来春季平均最高气温重建序列具有如下特征:①经历了7个偏暖阶段和6个偏冷阶段;②存在7~18 a、30 a明显的准周期变化;③在1886年发生过一次明显的突变。

Abstract:

The tree-ring chronologies were established according to samples from the Hutubi River Basin, northern slopes of Tianshan Mountains. Single correlation screen indicated that the correlations were significant between the tree-ring residual chronologies and the mean maximum temperature from May to June, and the maximum correlation coefficient was 0.505. At the same time, the result has distinct physiological significance. With 3 tree-ring residual chronologies in Kayinsayi(t), Kayinsayi(t+1) and Xirekejiurete(t+1), the mean maximum temperature in the recent 313 years was well reconstructed, and the reconstructed equation was stable proved by crossing-test. The main results are as follows:①The reconstructed temperature series had 7 warm periods above its mean and 6 cold periods bellow its mean; ②The reconstructed temperature series from May to June in the Hutubi River Basin during the last 313 years had significant period cycles of 7~18 years, 30 years; ③The abrupt change of temperature occurred in 1886.

Key words: Hutubi River Basin, tree-ring residual chronology, maximum temperature, characteristic analysis
