利用采自阿勒泰中部地区森林中下部林缘(1354~1970 m)5个采点的西伯利亚落叶松(Larix sibirica Ledeb.)及1个采点的西伯利亚云杉(Picea obovata Ledeb)样本,建立树轮宽度年表,分析年表特征参数的气候指示意义表明:在6个年表中,拜克托别标准化树轮宽度年表的信噪比和样本对总体的代表性最大、平均敏感度较高、一阶自相关较小,表明该标准化树轮宽度年表所包含的气候信息可能最为丰富,其次是大东沟前标准化树轮宽度年表。依据年表间的互相关系数,合成了由拜克托别和大东沟前2个采点构成的区域年表BKQ以及由拜克托别、大东沟前、二道房南和贾登屿4个采点组成的区域年表BDEJ。分析6个单点年表及2个区域年表对气候的响应发现,拜克托别年表相对于其它5个单点年表及2个区域年表,在重建阿勒泰气象站6—8月降水量方面可能具有很好的应用潜力,而区域年表(BDEJ)则在重建阿勒泰气象站4—8月降水日数方面可能具有很好的应用潜力。
利用採自阿勒泰中部地區森林中下部林緣(1354~1970 m)5箇採點的西伯利亞落葉鬆(Larix sibirica Ledeb.)及1箇採點的西伯利亞雲杉(Picea obovata Ledeb)樣本,建立樹輪寬度年錶,分析年錶特徵參數的氣候指示意義錶明:在6箇年錶中,拜剋託彆標準化樹輪寬度年錶的信譟比和樣本對總體的代錶性最大、平均敏感度較高、一階自相關較小,錶明該標準化樹輪寬度年錶所包含的氣候信息可能最為豐富,其次是大東溝前標準化樹輪寬度年錶。依據年錶間的互相關繫數,閤成瞭由拜剋託彆和大東溝前2箇採點構成的區域年錶BKQ以及由拜剋託彆、大東溝前、二道房南和賈登嶼4箇採點組成的區域年錶BDEJ。分析6箇單點年錶及2箇區域年錶對氣候的響應髮現,拜剋託彆年錶相對于其它5箇單點年錶及2箇區域年錶,在重建阿勒泰氣象站6—8月降水量方麵可能具有很好的應用潛力,而區域年錶(BDEJ)則在重建阿勒泰氣象站4—8月降水日數方麵可能具有很好的應用潛力。

Six tree-ring cores of Larix sibirica Ledeb and Picea obovata Ledeb were sampled from the middle of Altay at the lower elevation of 1 354~1 970 m. Six tree-ring width chronologies were developed using standard dendrochronological methods, and the features and their climatic information were analyzed in this paper. It shows that:among all the six sampling sites,the sample representative and signal-noise ratio of the standardized chronology of BKL is the highest, with the higher mean sensitivity,smaller order autocorrelation; it shows that the standardized chronology of BKL contained possibly most climate information and that of DDQ contained the second more . According to the number of mutual relations between tree-ring width chronologies, the regional chronology of BKQ was synthesized by the two Collect points from BKL and DDQ and the regional chronology of BDEJ was synthesized by the four Collect points of BKL、DDQ、EDN and JDQ. Analysis of six chronologies and two regional chronologies climate response found that compared to the other five single point chronologies and two regional chronologies, in the reconstruction of precipitation series for Altay weather stations from June to August, BKL chronology may had a very good application potential and the regional chronology of BDEJ in the reconstruction of rainy days for Altay weather stations from April to August may have a very good application potential.
