      摘要: 對(duì)黑龍江省小興安嶺五營豐林國家自然保護(hù)區(qū)建立的紅松 (Pinus koraiensis) 樹輪寬度年表與五營氣象站的氣候要素響應(yīng)分析表明,樹輪年表與生長季上一年10月份的平均溫度顯著相關(guān),由此重建了1796-2004年五營10月份平均溫度。此外,4月下旬的溫度變化對(duì)五營紅松樹木的徑向生長也具有一定的影響。1796-2004年,五營共經(jīng)歷了4個(gè)偏冷和4個(gè)偏暖期。周期分析表明,重建序列以3.33 a的周期最為顯著,對(duì)重建序列30 a尺度的突變檢驗(yàn)結(jié)果表明,1871年和1900年前后,五營地區(qū)10月份平均溫度出現(xiàn)了顯著的均值突變,1851年前后出現(xiàn)了明顯的方差突變。

      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.
