Abstract In this paper, some statistics results of the five tree-ring standardized chronologies of the west of Altay from ARSTAN program were compared. The results indicated that the Shaleha chronology contains the most climatic information and the Kemu chronology contains the least. The contrast of the correlation coefficients between the tree-ring chronologies showed that the correlation coefficient between the Shaleha chronology and the Hanasinan chronology is 0.676 and is the highest, which located near the upper limit of the forest. But the correlation coefficient between the Hanasibei chronology and the Kemu chronology that located near the edge of the forest is 0.586, and the two chronologies have low correlation with the three chronologies that located near the upper limit of the forest. The correlation analysis showed that there is negative correlation between the tree-ring width index of the three chronologies which located near the upper limit of the forest and the precipitation from June to August (the highest coefficient -0.535, the significance level 0.0002), and positive correlation with the mean temperature from June to July in the prior growing season(the highest coefficient 0.426, the significance level 0.035); there is positive correlation between the tree-ring width index of the two chronologies which located near the lower limit of the forest and the precipitation of January (the highest coefficient 0.455, the significance level 0.0019), and the correlation has certain physiological significance. At 0.10 significance level, the tree-ring width index fluctuations of the other four chronologies appeared the period of 2.4-year except the Jikeyin chronology. Besides, the Jikeyin chronology and the Kemu chronology all showed the quasi-periods of 13.5-year and 14.4-year, and the Hanasinan chronology and the Shaleha chronology all showed the quasi-periods of 23.0-year and 38.3-year. The content of the high-frequency information is stronger than that of the low-frequency information in the tree-ring chronologies of the west of Altay.
