Abstract

Abstract Peatland Norway spruce (Picea abies L. Karst.) forests represent very valuable ecosystems with considerable importance for nature conservation. However, a lot of peatland forests have been drained or used for opencast mining of peat. Since dendrochronological and dendroecological studies on trees growing on peatlands in Europe are not many, this study aimed to reconstruct the impact of drainage to the growth of trees in forest stands older than 100 years in the moment of drainage. Dendrochronological analysis was performed on two 0.25-ha square sampling plots (50*50 m) in two pre-selected stands (control site vs. drained site) with similar natural conditions and age. The mean-value functions of the ring indices, comparing the drained site with the control site, in the period after 1940 revealed very similar radial-growth trends. After the year 1992, when one site was substantially drained, the radial-growth trends not showed any significant change. Likewise, the result of the independent two sample t-test for the period after 1992 has not revealed any substantial statistically important difference in the mean index between the control site and the drained site.

土壤排水对泥炭地挪威云杉径向茎生长的影响

泥炭地挪威云杉(Picea abies L. Karst.)森林是一种非常有价值的生态系统，对自然保护具有重要意义。然而，许多泥炭地森林已被抽干或用于露天开采泥炭。由于欧洲泥炭地树木的树木年代学和树木生态学研究并不多，本研究旨在重建排水时刻对100年以上林分树木生长的影响。在自然条件和树龄相似的两个预选林分(对照林分和排水林分)中，对两个0.25 ha的采样样地(50*50 m)进行了树木年代学分析。1940年以后，排水场地与对照场地环指数的均值函数显示出非常相似的径向增长趋势。1992年之后，当一个地点基本上干涸后，径向增长趋势没有显示出任何重大变化。同样，1992年以后的独立双样本t检验结果也没有显示对照点和排水点的平均指数有显著的统计学差异。
