中文摘要：
相关分析表明，内蒙古阿尔山落叶松树轮宽度指数与5-9月平均温度显著负相关．在此基础上，设计转换方程重建了该地区1822--2008年间5-9月平均温度变化，重建序列的方差解释量达到39．9％。重建温度序列表明，温度低于多年平均值（1822--2008年）的时段有1822—1841年、1893--1906年、1931—1941年和1980--1992年；而温度高于多年平均值的时段有1842—1871年、1880--1892、1914—1930年、1942--1969年和1993--2003年。对比表明，阿尔山地区的温度重建序列与周边地区几条降水序列存在着高温和少雨的对应关系。
英文摘要：
The correlation analysis showed that the ring-width chronology was significantly correlated with the mean temperature from May to September in Arxan, Inner Mongolia. Based on the multiple regression model, the May--September mean temperature was reconstructed for Arxan for the past 187 years （1822--2008）. The reconstruction can explain 39.9% variance of the observation. The reconstructed temperature series showed four cold intervals （1822--1841, 1893--1906, 1931--1941 and 1980-- 1992） and five warm intervals （1842--1871, 1880--1892, 1914--1930, 1942--1969 and 1993-- 2003 ）. The reconstruction of the temperature showed a large regional representativeness after comparing with a nearby tree-ring based temperature series in Weichang. Moreover, the comparison with other tree-ring based precipitation series around the studied site showed that the high temperature period of Arxan corresponded with the dry period of regions in northeastern China.
