Research data

The datasets used in this study were obtained from publicly available online sources, as summarized in the submitted data-source table. The boundary of the study area was defined using the 2021 version of the Qinghai-Tibet Plateau boundary shapefile. All input datasets were preprocessed, clipped to the study-area boundary, and harmonized to a consistent spatial framework prior to analysis. These data were used to derive the RUSLE factors, landscape metrics, and explanatory variables for the investigation of water-erosion dynamics and threshold-driven mechanisms on the Qinghai-Tibet Plateau.
