Responses to alternative harvesting practices in drained peatland forest: water table level and spruce needle chlorophyll fluorescence

Data used in the research article “Vegetation controls of water and energy balance of a drained peatland forest: responses to alternative harvesting practices” (Haahti et al., AFM 2020): spruce_Fv_FM.csv contains the ratio of variable chlorophyll fluorescence to maximal chlorophyll fluorescence (Fv/Fm) measured from current-year and one-year-old spruce needles in the partial harvested (n=50) and the non-harvested (n=20) stand during two post-treatment growing seasons. WTL.csv contains the processed daily water table level as distance from the soil surface (mean, maximum, minimum) for the non-harvested stand (2010-2018) and for the clear-cut and partial harvested sites (2016-2018).

本数据集源自研究论文《排水泥炭地森林的水分与能量平衡植被调控因子：不同采伐方式的响应》（Haahti等，《农业与森林气象学（AFM）》2020）：
spruce_Fv_FM.csv 文件收录了两个采伐后生长季期间，于部分采伐林分（样本量n=50）与未采伐林分（样本量n=20）中，从当年生和一年生云杉针叶上测得的可变叶绿素荧光与最大叶绿素荧光比值（Fv/Fm）。
WTL.csv 文件包含经预处理的日地下水位数据，以距土壤表面的距离为度量单位，涵盖未采伐样地（2010-2018年）的日均、最高及最低水位，以及皆伐样地和部分采伐样地（2016-2018年）的对应统计值。
