Processed sub-basin data and reproducible statistical analyses for soil erosion regulation in Mizhi County, China

This dataset provides processed sub-basin attributes, spatial geometries, and statistical analysis code supporting the study "A natural constraint–planning response framework for analyzing soil erosion regulation in the Loess hilly-gully region". The study area is Mizhi County, located in the Loess Plateau of China. The dataset includes three sub-basin delineation scales defined using flow-accumulation thresholds of 500, 1000, and 2000 cells, corresponding to 1,616, 751, and 370 sub-basins, respectively. The processed indicators include natural erosion potential (NEP), fractional vegetation cover (FVC), terrace proportion (TERRACE), composite human pressure (CHP), and model-estimated soil erosion intensity (SE), together with their relevant component variables. The archive contains CSV attribute tables, a GeoPackage with sub-basin geometries, a Python script for reproducing the principal regression and spatial-inference analyses, and documentation of the variables and computational requirements. The package supports reproducibility of the principal statistical analyses from processed sub-basin inputs. It does not include the original third-party remote-sensing datasets or the complete GIS preprocessing workflow. Original data sources are identified in the associated manuscript.
