项目摘要

The impact of anticipated global change on growth and productivity of Norway spruce and European beech is still discussed controversially. The analysis of inter- and intra-annual growth dynamics in different environmental conditions will provide detailed insight into the resilience and adaption potential of stem radial growth to climatic extreme events and environmental changes.This study will be based on the exploitation of already existing unique long dendrometer time series collected at three dendroecological field sites of the Institute for Forest Growth along an altitudinal gradient in south-western Germany. At the three field sites, stem radial displacement of beech and spruce sample trees has been recorded by automatic precision point dendrometers in high temporal resolution (every 15 minutes) since 1990 at an altitude of 1250 m and since 1997 in addition at 450 m and 750 m. At these sites meteorological and pedological parameters have been measured during this observation period. Complementary environmental data, including high resolution time series of tropospheric CO2 concentration measurements from the nearby environmental monitoring station "Schauinsland" of the German Federal Environmental Agency (Umweltbundesamt) will be available. For extension of the retrospective analyses, stem discs and increment cores of dendrometer trees and neighboring trees will be sampled at each of the three sites.The innovative approach of combining long-term dendrometer data with tree ring features such as ring width, cell structure, intra-annual density profiles and data from detailed studies on cambial activity and wood formation, provides a great opportunity to deepen our understanding and knowledge about the interactions of different environmental factors with the short-, medium- and long-term growth dynamics of the two important tree species in German forestry.

预期的全球变化对挪威云杉和欧洲山毛榉的生长和生产力的影响仍然存在争议。对不同环境条件下的年际和年内生长动态的分析将有助于详细了解茎径向生长对气候极端事件和环境变化的恢复力和适应潜力。这项研究将基于利用现有的独特的长期树木计时间序列是在德国西南部森林生长研究所的三个树木生态学现场沿海拔梯度收集的。在这三个现场，自 1990 年以来，山毛榉和云杉样本树的茎径向位移已通过自动精密点树仪以高时间分辨率（每 15 分钟）记录，自 1990 年以来在海拔 1250 m 处记录，自 1997 年起在海拔 450 m 和 750 m 处记录。米。在此观测期间，在这些地点测量了气象和土壤参数。将提供补充环境数据，包括来自德国联邦环境局 (Umweltbundesamt) 附近环境监测站“Schauinsland”的对流层二氧化碳浓度测量的高分辨率时间序列。为了扩展回顾性分析，将在三个地点的每一个地点对树木测量仪树木和邻近树木的茎盘和增量核心进行采样。将长期树木测量仪数据与树木年轮特征（例如年轮宽度、细胞结构、年内密度剖面和来自对形成层活动和木材形成的详细研究的数据，为加深我们对不同环境因素与两者的短期、中期和长期生长动态之间的相互作用的理解和认识提供了很好的机会德国林业的重要树种。
