摘  要：
以内蒙古红花尔基樟子松林国家级自然保护区的天然樟子松(Pinus sylvestris var.mongolica)为样本,建立天然樟子松树木年轮宽度年表,研究天然樟子松的年轮宽度变化对气候变化的响应。结果表明,研究区域在器测时段(1953—2012)具有明显的暖干化趋势。树轮标准年表的可靠起止时段为1841—2013年,共173年,有效树轮指数的均值和标准差分别为0.955和0.277。极端低生长年份发生33次,极端高生长年份发生26次,分别占总有效年份的19.08%和15.03%。树轮宽度指数与当年3月的降水、当年2月、3月和5月标准蒸散显著正相关。年表与温度的响应总体表现在与当年1月到5月温度均为负相关但不显著。樟子松宽度年表与关键月份水分因子具有正相关响应,而与温度表现为负相关响应,表明生长季前期的水分胁迫是限制树木生长的主要因素。

摘  要：
Taking Pinus sylvestris var.mongolicaas a sample,the chronology of the tree rings of Pinus sylvestris var.mongolica was established,and the correlation analysis was applied to study the response of the changes in ring width of Pinus sylvestris var.mongolicato climate change.Result shows that there is a significant warming and drying trend during the period of measurement(1953-2012).The reliable of the standard chronology is 1841-2013,with a total of 173 years.The mean &standard deviation of the effective tree-ring index are 0.955 &0.277,respectively.The extreme low &high growth years occurred 33 &26 times during 1841-2013,respectively,accounting for 19.08% &15.03%of the total effective years.The tree-ring width index was significantly positively correlated with the precipitation in March of current year,and significantly positively correlated with the standard evapotranspiration in February,March & May of the current year.The relationship between the chronology &temperature was negative in January & May,but not significant.It indicates that water stress in the early growth season is the main factor limiting tree growth.
