| 摘 要： | 根据我国西部祁连山区一个三棵园柏平均年轮资料表、陕西一个太白落叶松(A)年轮宽度表和新疆哈密地区五个年轮年表,经过合适取样和精确定年的树木年轮序列和我国西部28个站点1951—1975年的年平均气温资料,采用一种恢复气象要素场的EOF迭代方案重建我国西部近600年的地面气温序列。初步计算结果表明:重建的气温序列反映出1432-1526年、1622-1680年、1834-1865年三个冷期以及1541-1567年、1897-1923年两个暖期。与近600年气候变迁的演变趋势基本吻合。

| Abstract: | By adopting the EOF iterative formulae for recovering the meteorological fac-tor fields,the recent 600 year temperature sequence in western China is rebuild aftersuitable sampling and accurate determination of the year of tree annual ring sequencefrom seven tables, namely,a data table of average annual ring of three junipers in theQilian Mountains, a table of annual ring width of a Taibai epinette (A) in Shanxiprovince and 5 annual ring tables in Hami,the Xinjiang Uygur Autonomous Region andby use of the annual mean temperature data from 28 stations (1951-1975) in westernChina,The rebuild temperature sequence reveals three cold periods (1432-1526, 1622-1680 and 1834-1865) and two warm periods (1541-1567 and 1897-1923),which co-incide very well with the tendency of the climatic variations in the past 600 years. |
