| 中文摘要: |
| 利用采自阿勒泰中部地区6个低海拔(1354-1970m)样点的西伯利亚落叶松(Larix sibirica Ledeb.) 或西伯利亚云杉(Picea obovata Ledeb)样本,建立各采点的树轮宽度指数年表。分析标准化树轮宽度年表的特征参数及对气候的响应表明：1.拜克托别标准化树轮宽度年表包含的气候信息最多,其次是大东沟前标准化树轮宽度年表。2.6个标准化树轮宽度年表与阿勒泰中部地区自建站以来的气象数据进行相关普查发现拜克托别及大东沟前标准化树轮宽度年表与6-8月降水量、4-8月降水日数呈显著正相关,石人东年表与7-8月平均最高气温呈显著负相关。这些相关具有明确的树木生理学意义。 |
| 英文摘要: |
| The tree-ring cores of Larix sibirica Ledeb and Picea obovata Ledeb were sampled from six sites of the middle of Altay at the lower elevation of 1354-1970m. Six tree-ring width chronologies were developed using standard dendrochronological methods and the features and their climatic information of six standardization chronologies were analyzed in this paper. It shows that ：The BKL chronology contained more climatic signals followed by DDQ chronology. The six standardization chronologies and the meteorological data was also analyzed. It suggests that the BKL chronology and the precipitation from 6 to 8 and rainy days from 4 to 8 are positively correlated relationship. the SRD chronology and The highest monthly average temperature from 7 to 8 has significant negative correlation .The related was embedded with obvious tree physiological significance． |
