Source-data inventory and supplementary tables for event-scale runoff, sediment, and post-event soil moisture analyses in Xindiangou, Loess Plateau (1988–2023)

This dataset record accompanies the manuscript “Terraced forest restoration reorganizes event-scale runoff release, sediment-output risk, and shallow soil moisture on the Loess Plateau”. It provides a source-data inventory and supplementary tables supporting event-scale analyses of runoff initiation, runoff-release states, sediment-output risk, and post-event shallow soil moisture in the Xindiangou watershed, Suide County, Shaanxi Province, China. The study used long-term standard runoff-plot observations under four hillslope conditions: sloping cropland (AL), grassland (GL), Caragana shrubland (CL), and terraced Pinus tabulaeformis forest (TPF). Rainfall–runoff–sediment records cover 1988–2023 for AL, CL, and TPF, and 2001–2023 for GL. Post-event 30-cm soil moisture observations cover 2015–2023. These data were used to evaluate runoff occurrence, runoff coefficient, empirical S0/S1/S2 release-state classification, sediment concentration, event sediment yield, post-event θ30, and paired AL–TPF release–moisture indicators. The file “Research Data.xlsx” lists the original public data sources and repository links used to assemble the research dataset. The file “Supplementary Material.xlsx” contains supplementary tables supporting the manuscript, including data-flow accounting, runoff-initiation models, runoff-probability thresholds, release-state sensitivity analyses, sediment-output contrasts, post-event θ30 contrasts, AL–TPF paired indicators, common-period robustness analysis, API sensitivity analysis, high-release diagnostic modelling, and event-fixed-effect results. θ30 denotes post-event soil moisture at 30 cm depth and should not be interpreted as whole-profile soil water storage, deep recharge, infiltration amount, or groundwater response. Paired runoff–moisture indicators describe co-occurring event-response states and do not imply direct conversion of reduced runoff into shallow soil water storage. Users should also cite the original data sources listed in the source inventory where appropriate.本数据集配套论文《黄土高原梯田森林修复重构场次尺度径流排放、产沙风险与浅层土壤湿度》，提供源数据清单与补充表格，支撑中国陕西省绥德县辛店沟流域的径流起始、径流排放状态、产沙风险以及事件后浅层土壤湿度的场次尺度分析。 本研究针对四种坡面条件开展长期标准径流小区观测，分别为坡耕地（AL）、草地（GL）、柠条灌丛（CL）以及油松（Pinus tabulaeformis）梯田林（TPF）。AL、CL与TPF的降雨-径流-产沙序列覆盖1988-2023年，GL的该序列覆盖2001-2023年。事件后30cm深度土壤湿度观测覆盖2015-2023年。本数据集用于评估径流发生情况、径流系数、经验S0/S1/S2排放状态分类、泥沙浓度、场次产沙量、事件后θ30以及AL-TPF配对排放-湿度指标。 "研究数据.xlsx"文件列出了本研究数据集整合所用的公开原始数据源与仓库链接。"补充材料.xlsx"文件包含支撑论文的补充表格，涵盖数据流核算、径流起始模型、径流概率阈值、排放状态敏感性分析、产沙对比、事件后θ30对比、AL-TPF配对指标、共同时段稳健性分析、API敏感性分析、高排放诊断建模以及事件固定效应结果。 θ30指事件后30cm深度的土壤湿度，不可被解读为全剖面土壤储水量、深层补给、入渗量或地下水响应。配对径流-湿度指标描述同步发生的事件响应状态，并不意味着减少的径流可直接转化为浅层土壤储水。使用者还应在合适场景下引用源数据清单中列出的原始数据源。
