Supporting data and code for vegetation-mediated regulation of rainfall–runoff–erosion processes under climate variability in the Qinghai Lake Basin, Tibetan Plateau

This record contains processed summary tables, analysis scripts, geospatial boundary files, annual thematic maps, and publication-ready figures supporting the manuscript “Vegetation-mediated regulation of rainfall–runoff–erosion processes under climate variability in the Qinghai Lake Basin, Tibetan Plateau.” The study evaluates precipitation, rainfall erosivity, surface runoff, runoff coefficient, vegetation dynamics, modeled erosion susceptibility, land-cover change, vegetation counterfactuals, and persistent erosion-risk zones during 2001–2024. The analysis integrates CHIRPS precipitation, ERA5-Land runoff, MODIS vegetation indices, NASADEM terrain, MERIT Hydro contributing area, OpenLandMap soil texture, and annual CLCD land cover within a RUSLE-based erosion-susceptibility framework. The deposited materials include annual basin statistics, trend and change-point results, land-cover transition tables, erosion-risk class areas, counterfactual vegetation results, English publication figures, the K030100 Qinghai Lake water-system boundary, and the Python analysis script. Raw third-party source products are not redistributed and remain available from their original providers. RUSLE-derived values should be interpreted as modeled relative erosion-susceptibility indices rather than field-calibrated soil-loss rates or observed sediment yield.
