Abstract

Treeline isotherms are used in comparative and modelling studies to predict treeline positions. However, how representative local short-term temperature records are for a given region remains poorly understood. Furthermore, the predictive value of on-site temperatures for explaining tree growth requires further validation. Here we present temperature records and tree growth datasets from treeline ecotone sites differing in elevation and slope direction in the High Sudetes (Czechia and Poland). The goal was to determine the spatial and temporal variability of soil and air temperatures and to describe the relationship of various temperature metrics with tree growth. Our results demonstrate that, because of spatial and temporal variability, major temperature metrics used in comparative studies should be provided with an uncertainty range between 0.6 and 0.8 K for seasonal mean soil and air temperature. While soil temperatures exhibit high spatial variability, air temperatures vary more with time. Elevation is the most important driver of temperature patterns in treeline ecotones. Differences related to slope direction were important mainly for soil temperatures in lower parts of treeline ecotones. Tree growth is tightly related to June–September air temperature, with a modulating role of the onset date of soil temperature-defined growing season. In this study, we describe patterns of temperature variation in the treeline ecotones of two mountain ranges and demonstrate the extremely strong dependence of tree stem growth on air temperature, with very limited remaining space for other potentially limiting factors.

树线交错带与树木生长相关的气温和土壤温度的景观尺度变异性
树线等温线用于比较和建模研究,以预测树线位置。然而,对某一地区的当地短期温度记录的代表性仍知之甚少。此外,现场温度对解释树木生长的预测价值还需要进一步验证。在这里,我们展示了苏台德高地(捷克和波兰)不同海拔和坡度方向的树线交错带的温度记录和树木生长数据集。目的是确定土壤和空气温度的空间和时间变异性,并描述各种温度指标与树木生长的关系。我们的结果表明,由于空间和时间的可变性,比较研究中使用的主要温度指标的季节平均土壤和空气温度的不确定性范围应在0.6至0.8 K之间。虽然土壤温度表现出很高的空间变异性,但空气温度随时间的变化更大。海拔是树线交错带温度模式的最重要驱动因素。与坡度方向有关的差异主要对树线交错带下部的土壤温度很重要。树木生长与6月至9月的气温密切相关,土壤温度的开始日期对生长季节具有调节作用。在这项研究中,我们描述了两个山脉的树线交错带的温度变化模式,并证明了树干生长对气温的依赖性极强,其他潜在限制因素的剩余空间非常有限。
