| 摘 要： | 通过对尼勒克地区3个树轮宽度标准化年表有关参数的对比分析，证明萨克巴依顿年表和唐布拉年表比霍仕布拉克年表包含更多的气候信息。将这3个树轮宽度标准化年表与附近的尼勒克气象站1960--2008年月平均降水组合资料进行相关分析，结果表明：尼勒克3个树轮宽度标准化年表的年轮指数与尼勒克地区上年7—8月的降水呈显著正相关，其中唐布拉年表（TBL）的年轮指数与上年7—8月降水相关最佳，相关系数为0．575，达0．00002的极显著性水平，且二者的正相关具有明确的树木生理学意义。研究还发现，尼勒克3个树轮宽度标准化年表的低频信息含量均多于高频信息的含量，在0．05显著性水平上，普遍存在2～3a的变化准周期，且平均年表存在7个高指数阶段和7个低指数阶段。

| Abstract: | This paper compared and analyzed some parameters of three tree-ring width standardized chronologies in Nileke area. The results indicated that the Sakebayidun and Tangbula chronologies contain more climatic information than the Huoshibulake chronology. The correlation analysis between these tree-ring width index and the manthly average precipitation of Nileke station from 1960 to 2008 showed that there is a positive correlation between tree-ring width index of three chronologies and precipitation in July and August of the last year, with the maximum correlation of 0.575 （a=0.00002） occurred in the Tangbula＇s, which has distinct physiological significance. We also found that the information content of low-frequency vibration is more than that of the high-frequency vibration of the three chronologies in Nileke. The long-term tree-ring width chronologies have significant variation periods of 2-3 years at a significance level of 0.05, and the average chronology has seven low index periods and seven high index periods. |
