Abstract以大兴安岭北部根河、呼中和汗马冻土区落叶松和樟子松为样本,建立了五个树轮宽度年表,并计算获取了五个样点的树轮截面积指数(BAI)序列。树轮BAI-气候响应关系分析表明,气温为这一地区落叶松和樟子松生长的主要限制因子;但落叶松和樟子松对气候变化的响应存在差异。落叶松BAI与3月平均气温,樟子松BAI与前一年12月至当年4月平均气温均呈显著负相关。考虑到水热综合影响,落叶松BAI控制因子由1957-1990年与其呈显著正相关的1月份SPEI转变为1991-2013年与其呈显著正相关的1-4月SPEI和与其呈显著负相关的3月份平均气温;樟子松BAI控制因子则由1957-1990年与其呈显著负相关的2月和8月份平均气温转变为1991-2013年与其呈显著正相关的7月份降水量和6-7月SPEI。结果表明,在全球变暖背景下,水热环境改变使得冻土区树木生长限制因子发生变化。

以大兴安岭北部根河、呼中和汗马冻土区落叶松和樟子松为样本,建立了五个树轮宽度年表,并计算获取了五个样点的树轮截面积指数(BAI)序列。树轮BAI-气候响应关系分析表明,气温为这一地区落叶松和樟子松生长的主要限制因子;但落叶松和樟子松对气候变化的响应存在差异。落叶松BAI与3月平均气温,樟子松BAI与前一年12月至当年4月平均气温均呈显著负相关。考虑到水热综合影响,落叶松BAI控制因子由1957-1990年与其呈显著正相关的1月份SPEI转变为1991-2013年与其呈显著正相关的1-4月SPEI和与其呈显著负相关的3月份平均气温;樟子松BAI控制因子则由1957-1990年与其呈显著负相关的2月和8月份平均气温转变为1991-2013年与其呈显著正相关的7月份降水量和6-7月SPEI。结果表明,在全球变暖背景下,水热环境改变使得冻土区树木生长限制因子发生变化。

Based on the Dahurian Larch and Pinus sylvestris tree-ring samples taken from Genhe, Hanma and Huzhong permafrost regions in the north Great Higgnan Mountains, five tree-ring width chronologies were established, and then the basal area increment (BAI) was calculated for the five sites. The response analysis showed that temperature was the dominant factor affecting the tree growth in these regions, with distinct difference between the two species. BAI of Dahurian Larch was significantly and negatively correlated with the monthly average temperature in March. BAI of Pinus sylvestris was significantly and negatively correlated with the monthly averaged temperature from previous December to current April. The climate limiting factor on the radial growth of Dahurian Larch had transformed from a significant negatively correlation with SPEI index in Janurary from 1957 to 1990 into a significant correlation with SPEI index from Janurary to April and temperature in March from 1991 to 2013, and the climate limiting factor for Pinus sylvestris had changed from a significant negative correlation with February and August temperatures from 1957 to 1990 to a significant correlation with precipitation in July and SPEI index from June to July from 1991 to 2013. These results indicated that the two species responding to climate change,especially,to temperature change,was different under the background of global warming,even the climate limiting factor on radial growth would change in different periods for the same species.
