摘要: 基于树木年代学的理论和方法,建立了大兴安岭满归地区樟子松年轮宽度年表,分析了标准化年表与该区主要气候因子(温度和降水)之间的相关关系,揭示了气候因子对树木径向生长的影响.结果表明: 当年4—8月的各月平均温度是研究区樟子松径向生长的主要限制因子;4—8月各月温度的不断升高对樟子松径向生长产生了不利影响.利用4—8月平均温度的变化模拟樟子松径向生长变异(1958—2008年),发现随着区域气候暖干化趋势的加强,该区樟子松生长将呈现出衰退的特征.

Abstract: Based on the theory and methodology of dendrochronology, the tree ring width chronology of Pinus sylvestris var. mongolica in Mangui of Great Xing’an Mountains was developed, and the relationships between the standardized tree ring width chronology and local climate factors (temperature and precipitation) as well as the effects of climate factors on the P. sylvestris var. mongolica radial growth were analyzed. In this region, the mean monthly temperature in April-August of current year was the main factor limiting the radial growth, and the increasing mean monthly temperature from April to August had negative effects to the radial growth. The simulation of the variations of the radial growth by the mean monthly temperature change in April-August showed that the radial growth of P. sylvestris var. mongolica would present a declining trend accompanied with the warmer and drier regional climate condition.

Key words: Pinus sylvestris var. mongolica, tree ring width chronology, climate warming, radial growth
