中文摘要	胡杨作为内陆干旱荒漠地区树龄较长的阔叶树种,是开展过去气候环境变化研究的宝贵材料。为了探讨胡杨树轮生长指标与气候环境之间的相关关系,本文在综述胡杨树种概况和生长区域气候环境特征的基础上,以新疆艾比湖流域胡杨为研究材料,利用树木年轮气候学分析方法,建立了艾比湖地区181年来的胡杨宽度年表。对宽度年表与精河、蔡家湖气象站的温度、降水序列进行了相关分析,结果表明,树轮宽度指标与冬半年降水呈正相关关系,相关系数最大为0.408,两个气象站中,精河站与年表相关系数高于蔡家湖站。通过与其他学者在该地区的研究成果对比分析,发现艾比湖胡杨树轮宽度指数高低时段与艾比湖湖面变化有很好的一致性,这与艾比湖地区地下水和湖面变化有密切关系,与胡杨生长受地下水变化影响的研究结论一致。
英文摘要	The Populus euphratica Oliv,a type of large tall broad-leaved trees in arid and semi-arid areas,has long life and plays an important role in the study of the paleo-environment because it is sensitive to climatic and environmental changes.This paper discusses the relationship between the tree-ring growths of Populus euphratica and the climate environmental conditions.Starting with a review of its general features and the geographic distribution,the conditions of climate,water resource,groundwater and soil in the distributional regions of Populus euphratica are analyzed.Two sets of tree-ring samples of Populus euphratica are collected from the eastern region of Aibi Lake basin in Xinjiang Province.By using the methods of dendrochrology,the tree-ring width chronologies of Guertu sampling sites are established,and the chronologies are 181 years long.The correlation analysis between the tree-ring width chronologies and the temperature and the precipitation of Jinghe and Caijiahu meteorological stations indicate that the tree-ring width chronologies and the precipitation are positively correlated in winter months.The comparison of two meteorological stations shows that the correlation coefficient of the Jinghe station is higher than that of the Caijiahu Station and the largest is 0.408.A qualitative analysis shows that the tree-ring width chronologies of Guertu and the level changes of Aibi Lake have a good consistency at the same time.These findings are consistent with the conclusions of other scholars in this area.The results show that tree ring width variation is sensitive to the groundwater level.
