摘　　要：利用阿勒泰西部地区8个采点的树轮资料,建立宽度年表,对比这些标准化树轮宽度年表的特征参数,并分析其与气候要素的相关性。结果表明:哈拉姆拉年表和贾登峪南年表含有相对较丰富的气候信息。森林上树线附近的哈拉姆拉年表与该区域当年6—7月的月平均最低气温呈正相关,其相关系数为0.422,显著性水平达0.004 3,而位于森林中下部林缘的贾登峪南年表与该区域上年12月—当年2月的降水量呈正相关,其相关系数为0.523,显著性水平达0.000 2,且二者的相关具有明确的树木生理学意义。This paper analyzed some parameters of the eight standardized tree-ring width chronologies in the west of Ahay,the results indicated that HLM and JDN chronologies contained more climatic information than the others. There was positive correlation between the HLM chronology which located near the upper limit of the forest and the mean low temperature during June-July in growing season with the correlation coefficient of 0.422 and the significance level of 0.0043, while there was positive correlation between the JDN chronology which located near the lower limit of the forest and the precipitation of last winter with the correlation coefficient of 0.523 and the significance level of 0.0002, and the correlation had certain physiological significance.
