采用树木年轮气候学方法,利用湖南炎陵资源冷杉的年轮宽度资料,建立了该地区1840～2010年的树标准化年表.分析表明,该地标准化年表与当年5～7月平均气温显著相关.在此基础上设计转换方程,重建该地区的5～7月平均气温.重建的温度序列有4个较为明显的冷期(1840～1866年、1879～1902年、1914～1924年1932～1940年):3个明显的暖期(1869～1877年、1905～1913年和1925～1930年).1999年之后升温明显.%By using the method of dendrochronology, a tree-ring width chronology from 1840 to 2010 has been built based on the data of Abies ziyuanemis tree-ring in Yanling county of Hunan province. The calculation results show that the data of the standardization (STD) chronology are significantly correlated with the mean air temperature from May to July in 2010. The mean temperatures of May to July at the sampling site were reconstructed by using the regression method. The reconstructed results indicate that four cold periods (1840-1866,1879-1902, 1914-1924,1932-1940) and three warm periods (1869-1877, 1905-1913,1925-1930) may be occurred. The mean temperature in the area may increased quickly after 1999.
