Geospatial modeling study reveals severe, heterogeneous soil loss across the Yanhe watershed, highlighting critical zones requiring targeted soil conservation.

Key Points

To evaluate large-scale annual soil loss and spatial erosion patterns across the Yanhe watershed using RUSLE combined with GIS.
Coupled the Revised Universal Soil Loss Equation (RUSLE) with Geographic Information Systems (GIS) to assess regional soil degradation.
Calculated five core RUSLE parameter layers (R-factor, K-factor, LS-factor, C-factor, and P-factor) using localized environmental and topographical data.
Mean RUSLE factors were calculated as R = 970,209 MJ km⁻² h⁻¹ a⁻¹, K = 0.0195 Mg h MJ⁻¹ mm⁻¹, LS = 10.27, C = 0.33359, and P = 0.2135.
Annual average soil loss averaged 14,458 Mg km⁻² per year, with rates in most areas falling between 5,000 and 20,000 Mg km⁻² per year.
Erosion rates were spatially uneven across the watershed, with substantially higher soil loss occurring in the central and southeastern sections than in the northwest.
