Silver fir is one of the most productive and ecologically valuable native European tree species, however, it has been experiencing decline which has periodically occurred over its natural range. This paper aims to investigate the recent climate-growth relationships of silver fir (Abies alba Mill.) and its temporal change along the course of its life. Long-term tree-ring databases, as well as records on climate, atmospheric SO2, NO3 and acid concentrations from four different regions in the Western Carpathians were used. The results provide clear evidence of significant increase of silver fir's radial increment over the entire Western Carpathian area since 1970-1980. The results indicated that the most probable factors behind the rapid recovery of tree radial increment were reductions in emissions of NO3 and SO2, alongside a significant increase in mean June, July and April temperatures.
银冷杉是欧洲最具生产力和生态价值的本地树种之一,但它在其自然分布范围内经历了周期性的衰退。本文旨在研究银冷杉(Abies alba Mill.)的近期气候-生长关系及其在生命过程中的时间变化。我们使用了来自喀尔巴阡山脉西部四个不同地区的长期树木年轮数据库以及气候、大气 SO2、NO3 和酸浓度记录。结果为自 20 世纪 70-80 年代以来,银冷杉的径向增量在整个喀尔巴阡山脉地区显著增加提供了明确证据。结果表明,导致树木径向增量快速恢复的最可能因素是 NO3 和 SO2 排放量的减少,以及 6 月、7 月和 4 月平均温度的显著升高。
