Dataset for "Small-scale spatial variability of hydro-physical properties of natural and degraded peat soils"

The objectives of this study were to analyze the spatial variability of hydro-physical properties in peat soils and to develop pedotransfer functions (PTFs) for estimating peat hydraulic properties using readily available soil parameters. The data set includes measurements from three study sites representing different peat degradation states (natural, degraded, and extremely degraded), where 72 undisturbed soil cores were collected from 5 m by 5 m grid cells within a 35 m by 40 m area at each site. Key parameters, such as saturated hydraulic conductivity, soil water retention curves (van Genuchten model parameters), total porosity, macroporosity, bulk density, and soil organic matter content, were determined. This dataset supports the findings of the publication: Wang, M., Liu, H., Lennartz, B., 2021. Small-scale spatial variability of hydro-physical properties of natural and degraded peat soils. Geoderma 399, 115123. And this study was conducted within the framework of the Research Training Group “Baltic TRANSCOAST” funded by the DFG (Deutsche Forschungsgemeinschaft) under grant number GRK2000.本研究旨在分析泥炭土水物理特性的空间变异特征，并基于易获取的土壤参数构建用于估算泥炭水力特性的土壤传递函数（pedotransfer functions，PTFs）。本数据集包含3个代表不同泥炭退化状态（天然原生、退化、极度退化）研究样地的实测数据：每个样地在35 m×40 m的研究区域内，于5 m×5 m的网格点位采集了72个原状土柱，并测定了饱和导水率、土壤水分特征曲线（van Genuchten模型参数）、总孔隙度、大孔隙度、容重及土壤有机质含量等关键参数。 本数据集支撑以下发表论文的研究结论：Wang, M., Liu, H., Lennartz, B., 2021. 《天然与退化泥炭土壤水物理特性的小尺度空间变异》，Geoderma，399卷，115123号论文。本研究系在由德国科学基金会（Deutsche Forschungsgemeinschaft，DFG）资助的“Baltic TRANSCOAST”研究培训小组框架下开展，项目编号为GRK2000。
