| 中文摘要: |
| 文中采用秦岭南坡陕西镇安鹰嘴崖建立的秦岭冷杉树木年轮年表,分析树木的径向生长对镇安地区气候要素变化的响应关系,重建镇安地区1755年以来的初春温度变化,并对重建序列进行了周期分析和突变分析。采用功率谱分析方法,得出镇安地区初春温度重建序列具有显著的准50a和准2～3a周期,而准40a、准9a和3.8a左右等周期也较为明显。而步长为30a的滑动t检验、滑动F检验和Lepage检验等突变检验结果表明,1798,1853,1884年等年前后,镇安地区初春温度序列出现了显著的均值突变,而在1944年前后镇安地区初春温度序列出现明显的方差突变。 |

| In this paper, March to April average temperature was reconstructed for the period of 1755 to 1992 using a standard treering chronology of Zhenan, Shanxi province.The Abies chensiensis Van Tieghem at Yingzuizai, Zhenan, whose altitude is about 2500 meters high, is significantly affected by the early-spring temperature.The correlation coefficient between the two is up to 0.7.The regression equation for the calibration period, 1958 to 1992, explains nearly 50% of calibrated variance, with the equation confidence level 0.01 and high significant cross-verification testing parameters.The quasififty and two～three years periods are found significant in the reconstructed series by power spectrum method.The averag evalueabr uptchanges happened in 1798, 1853, 1884, and the standard deviation abrupt change in 1944. |
