主　　题：Soil erosion vulnerability RUSLE model Combination weighting method Driving factors Spatial heterogeneity 

摘      要：Soil erosion has been recognized as a critical environmental issue *** previous studies have primarily focused on watershed-scale soil erosion vulnerability from a natural factor perspective,there is a notable gap in understanding the intricate interplay between natural and socio-economic factors,especially in the context of spatial heterogeneity and nonlinear impacts of human-land *** address this,our study evaluates the soil erosion vulnerability at a provincial scale,taking Hubei Province as a case study to explore the combined effects of natural and socio-economic *** developed an evaluation index system based on 15 indicators of soil erosion vulnerability:exposure,sensitivity,and *** addition,the combination weighting method was applied to determine index weights,and the spatial interaction was analyzed using spatial autocorrelation,geographical temporally weighted regression and geographical *** results showed an overall decreasing soil erosion intensity in Hubei Province during 2000 and *** soil erosion vulnerability increased before 2000 and *** areas with high soil erosion vulnerability were mainly confined in the central and southern regions of Hubei Province(Xiantao,Tianmen,Qianjiang and Ezhou)with obvious spatial aggregation that intensified over *** factors(habitat quality index)had negative impacts on soil erosion vulnerability,whereas socio-economic factors(population density)showed substantial spatial variability in their *** was a positive correlation between soil erosion vulnerability and erosion intensity,with the correlation coefficients ranging from-0.41 and *** increase of slope was found to enhance the positive correlation between soil erosion vulnerability and intensity.
