研究挪威云杉（Picea abies L.）喀斯特）作为欧洲东南部阿尔卑斯山的古气候档案，树木年轮年表是从斯洛文尼亚两个不同生态和气候特征的地点生长的树木中发展起来的。年轮宽度，最大晚材密度，年高度增量和晚材纤维素碳同位素组成的测定在这两个网站和由此产生的时间序列进行比较，并验证仪器气候数据的共同时期（公元1960年至公元2002年）。结果表明，环宽度对夏季温度的敏感性是非常站点依赖的，在高山和低地网站相反的反应。最大密度响应9月的温度，表明木质化后细胞分裂已经停止。稳定碳同位素最具潜力，对高山和低地林分的夏季温度反应强烈。高度增量出现相对不敏感的气候，可能是当地的立场动态为主。
To investigate the potential of Norway spruce (Picea abies L. Karst) as a palaeoclimate archive in the southeastern European Alps, tree ring chronologies were developed from trees growing at two sites in Slovenia which differed in their ecological and climatological characteristics. Ring width, maximum latewood density, annual height increment and latewood cellulose carbon isotope composition were determined at both sites and the resulting time-series compared with and verified against instrumental climate data for their common period (AD 1960-AD 2002). Results indicate that ring width sensitivity to summer temperature is very site-dependent, with opposing responses at alpine and lowland sites. Maximum density responds to September temperatures, indicating lignification after cell division has ceased. Stable carbon isotopes have most potential, responding strongly to summer temperature in both alpine and lowland stands. Height increment appears relatively insensitive to climate, and is likely to be dominated by local stand dynamics.
