Based on a standardized tree-ring width chronology established at Altay, Xinjiang, we examined the climatic and hydrological factors affecting the tree-ring width of . The results showed that the tree-ring width chronology of was negatively correlated with the average temperature and the average maximum temperature in May-June of current year and positively correlated with May-June PDSI and January-June precipitation. The tree-ring width chronology of was positively correlated with previous November runoff of the Irtysh River. The radial growth of was affected by temperature and precipitation, with precipitation in early stage of tree growth and temperature in summer being the key climatic factors. The study of the extreme years of chronology showed that the radial growth of was related to ENSO events and global large-scale circulations. By affecting the location of cyclones over Central Asia, ENSO affected water vapor transport to Altay, with consequences on the radial growth of
基于在新疆阿勒泰建立的标准化树轮宽度年表，我们研究了影响[具体树种]树轮宽度的气候和水文因素。结果表明，[具体树种]的树轮宽度年表与当年5 - 6月的平均温度和平均最高温度呈负相关，与5 - 6月的标准化降水蒸散指数（PDSI）和1 - 6月降水量呈正相关。[具体树种]的树轮宽度年表与额尔齐斯河上一年11月的径流量呈正相关。[具体树种]的径向生长受温度和降水影响，树木生长早期的降水和夏季的温度是关键气候因素。对年表极端年份的研究表明，[具体树种]的径向生长与厄尔尼诺 - 南方涛动（ENSO）事件和全球大尺度环流有关。ENSO通过影响中亚气旋的位置，影响水汽向阿勒泰的输送，从而对[具体树种]的径向生长产生影响。
