资源简介:
Data from a 17-year-long irrigation experiment (Pfynwald, Switzerland) in a naturally dry forest dominated by 100-year-old pine trees (Pinus sylvestris).
Data include: (1) properties of soils sampled in 2011 and 2019 (SOC and N concentrations and stocks, soil masses, 13C and 15N natural abundances, C/N ratios, clay content, pH, inorganic C, stoniness, bulk density); (2) litter mass loss and initial litter chemistry of dominant tree species (Quercus, Pinus, Viburnum) from a litter decomposition experiment carried out in 2014-2015; (3) soil fauna abundance sampled in 2015; (4) soil volumetric water content and soil temperature at 10 cm depth measured during the litter decomposition experiment in 2014-2015; (5) soil mesofauna (Acari and Collembola) diversity and community composition from sampling in 2017; (6) irrigation-induced changes in litterfall (2013-2014, 2016-2017), fine-root production (data 2015 from Brunner et al., 2019, Frontiers in Plant Science), annual soil respiration (estimated for 2014-2015), litter mass loss from litter decomposition experiment (May-October 2014), and SOC stocks measured in 2011 and 2019; (7) Moisture dependency of microbial soil respiration (0-10 cm depth, adapted from Joseph et al., 2020 PNAS), soil respiration measured in 2015 and abundance of Acari, Collembola and Lumbricidae sampled in 2015.
本数据集源自瑞士Pfynwald地区一项为期17年的灌溉实验,实验样地为以百年生欧洲赤松(Pinus sylvestris)为优势种的天然干旱林。数据集包含以下7类内容:1. 2011年与2019年采集的土壤样品属性,包括土壤有机碳(SOC)与氮浓度、储量,土壤质量,碳13(¹³C)与氮15(¹⁵N)自然丰度,碳氮比,黏粒含量,pH值,无机碳含量,石砾度,容重;2. 2014-2015年开展的枯落物分解实验中,优势树种(栎属Quercus、松属Pinus、荚蒾属Viburnum)的枯落物质量损失率及初始枯落物化学特征;3. 2015年采集的土壤动物丰度数据;4. 2014-2015年枯落物分解实验期间,10 cm深度处的土壤体积含水量与土壤温度;5. 2017年采样获得的土壤中型动物(螨形纲Acari、弹尾纲Collembola)多样性及群落组成;6. 灌溉对枯落物输入量的影响(2013-2014年、2016-2017年)、细根产量(2015年数据源自Brunner等2019年发表于《植物科学前沿》(Frontiers in Plant Science)的研究)、2014-2015年的年土壤呼吸估算值、2014年5-10月枯落物分解实验得到的枯落物质量损失率,以及2011年与2019年测定的土壤有机碳储量;7. 土壤微生物呼吸的湿度依赖性(0-10 cm深度,改编自Joseph等2020年发表于《美国国家科学院院刊》(PNAS)的研究)、2015年测定的土壤呼吸数据,以及2015年采集的螨形纲、弹尾纲与正蚓科(Lumbricidae)动物丰度。
