阿勒泰柯姆地区树轮宽度年表与灰度年表的建立

The Establishment of Tree-ring Width Chronologies and Tree-ring Gray Chronologies of Kemu Sampling Sites in the West of Altay

通过对比柯姆采点的8个标准化宽度和灰度树轮年表的多项特征参数,表明宽度年表在多项年表特征参数上均大大高于灰度年表。通过相关普查得出,标准化晚材灰度年表与当年7月至8月的降水量的相关系数最高,为0.426,显著性水平达0.001,而标准化早材灰度年表与上年12月至当年2月的月平均温度的相关系数最高,为0.362,显著性水平达0.02,且二者的相关具有明确的树木生理学意义。在0.10的显著性水平上,3个宽度年表均具有14a和3.4a左右的变化准周期,而5个灰度年表均存在2.2～2.4a的变化准周期。

In this paper, we compared some statistics results of eight tree-ring standard width and gray chronologies of Kemu sampling sites in the West of Ahay from ARSTAN program, the results indicated that the statistics characteristic parameters of the tree-ring standard width chronologies are all higher than the same of gray chronologies. The correlation between these chronology indexes and the meteorological factor of Buerjin weather station showed that there is the positive correlation between the latewood gray chronology and precipitation from Jun. to Aug., and the positive correlation between the earlywood gray chronology and monthly average temperature from Dec. to Feb. before the prior growing season. The maximum correlation coefficients are 0.462 （α=0.001） and 0.362 （α=0.02） respectively. At the same time, an explanation of its three tree-ring standard width chronologies appeared the quasi-peri physiology was presented. The od of 14 a and 3.4 a, and the five tree-ring standard gray chronologies all showed the quasi-period of 2.2-2.4 a, the significant level of both was α=0.10.
