中文摘要：

以小兴安岭凉水自然保护区红松为样本，运用树木年轮学分析方法，建立了红松树轮宽度年表，并运用相关分析、单年分析探讨了其与该地区气温、降水等气候因子的关系。结果表明，小兴安岭凉水红松生长受气温和降水共同影响，且主要受生长季前冬末春初（2～4月）低温及生长季气温和降水限制：红松年表与上年6、7月份和当年2、4月份均温呈显著正相关，同时其与月最高温和最低温呈现出与月均温相关性相似的趋势，表明红松生长受生长季前及生长季气温影响较大。仅有6月份均温和最高温与红松年表呈现明显的负相关关系，当年3、6月份降水对红松生长产生明显的正影响，说明红松除受生长季气温影响外，还受6月土壤含水率的影响。6月份过高温度加速土壤蒸发、植物蒸腾，与7月相比6月份降雨明显偏少，无法弥补土壤水分损失，致使树木生长受水分胁迫从而形成窄轮。对红松生长最大年（2009年）和最小年（1921年）的单年分析也进一步验证了上述相关分析的结果。我们的发现说明，小兴安岭凉水地区红松树木生长主要受生长季及生长季前气温和降水综合影响，并受6月土壤含水率限制。

英文摘要：

We developed one tree-ring chronology of Korean pine （Pinus koraiensis ） in Liangshui National Natural Reserve, Xiaoxing＇an Mountain, Northeast China, by using traditional dendrochronology. We identified the relationships between Korean pine chronology and monthly climatic factors （air temperatures and precipitation） by correlation analysis and single year analysis. Korean pine radial growth was mainly limited by both monthly air temperatures and precipitation, and the limited effects of minimum temperatures before growing season （from February to April） and mean temperatures and precipitation during growing season on Korean pine growth were most significant, and Korean pine radial growth was positively correlated with temperatures in the previous June and July and the current February and April. The responses of the chronology to monthly maximum and minimum temperatures showed a similar relationship with monthly mean temperatures, which indicated that Korean pine radial growth were mainly influenced by air temperatures before and during growing seasons. The chronology was negatively correlated with maximum and mean temperature in June of the current year, and positively correlated with precipitations in March and June. The soil moisture in June also had a significant influence on Korean pine growth. High temperature in June accelerates soil evaporation and plant transpiration, resulted in water stress and narrow ring formation of Korean pine in this region. Single year analysis confirmed the results from correlation analysis. Therefore, Korean pine radial growth was synthetically affected by precipitation and temperature during and before growing seasons, and also seriously limited by soil moisture in June.
