| 摘 要： | 对黑龙江省小兴安岭五营丰林国家自然保护区建立的红松 (Pinus koraiensis) 树轮宽度年表与五营气象站的气候要素响应分析表明，树轮年表与生长季上一年10月份的平均温度显著相关，由此重建了1796-2004年五营10月份平均温度。此外，4月下旬的温度变化对五营红松树木的径向生长也具有一定的影响。1796-2004年，五营共经历了4个偏冷和4个偏暖期。周期分析表明，重建序列以3.33 a的周期最为显著，对重建序列30 a尺度的突变检验结果表明，1871年和1900年前后，五营地区10月份平均温度出现了显著的均值突变，1851年前后出现了明显的方差突变。

| Abstract: | The growth of Pinus koraiensis at the Fenglin national natural reserve of Wuying, Heilongjiang Province, is significantly correlated with the local October temperature of previous year. The mean temperature of October in Wuying was reconstructed for the period of 1796-2004 using residual tree ring chronology. In addition, the temperature in the late dekad of April also affected the tree ring radial width to some extent. In the past 209 years, there were 4 colder periods and 4 warmer periods in the reconstructed series; the most significant period of 3.33 years was detected by the power spectrum method. The abrupt changes on 30-year time scale were also detected in the reconstructed series by the smoothing T-test, the smoothing F-test and the Lepage-test; the significant abrupt changes in mean value were presented in about 1871 and 1900, and the significant abrupt changes in standard deviation in about 1851. |
