运用树木年代学的基本原理和方法，研究三明地区马尾松（ Pinus massiniana ）径向生长对气候要素的响应。结果表明：夏季温度限制着马尾松的径向生长，年轮宽度与上一年和当年7-8月平均气温均呈显著负相关（ P＜0.01）；马尾松的径向生长受到降水和湿度的影响较大，与上一年1-3月降水量和2-3月平均相对湿度显著负相关（ P＜0.01），与当年6-11月平均降水量和7-8月相对湿度显著正相关（ P＜0.01）；同时宽度年表与上一年2-3月太阳日照时数显著正相关（ P＜0.01）；另外，宽度年表与6-11月PDSI显著正相关（ P＜0.05），生长季的干旱胁迫抑制了马尾松的生长。研究说明本地区限制马尾松树木生长的因素较多，1年中不同时期限制马尾松径向生长的气候因子不同。

According to the standard principles and methods of Dendrochronology , we used the tree-ring samples of Pinus massiniana in Sanming to study their responses to climate change .The results of correlation analysis showed that the radial growth of Pinus massiniana was significantly correlated with the July-August temperature in the previous year and the July-August mean temperature of the current year ( P<0.01 ) .The radial growth showed significant correlations with the precipitation from last year January-March ( P<0.01 ) and current year June-November ( P<0.01 ) .The chronology had signifi-cant correlations with the relative humidity in the previous February-March ( P<0.01 ) and the current July-August ( P<0.01 ) .Besides , significant positive correlations were observed between the tree ring width and the sunshine hours of the previous February-March ( P<0.01 ) .In addition, the growth of Pinus massoniana showed significant positive correlations with PDSI from June to November , suggesting a drought stressed growth pattern .Our study indicates that tree growth in this region is influenced by various factors and the climate-growth relationships vary over time within a year .
