The Yellow River Basin in Inner Mongolia is an important ecological region in China.Exploring changes in habitat quality and their driving factors is important for regional desertification prevention and biodi-versity conservation.Using land use/cover data from 1990 to 2020,GIS technology,and the InVEST model,the habitat quality of the region was assessed,and the driving factors of the spatial heterogeneity of habitat quality were analyzed using geographic detectors.The results indicated the following:(1)The overall spatial distribution pattern of habitat quality in the study area was low in the north and high in the south,with a positive spatial corre-lation and significant spatial clustering.Areas with low habitat quality,accounting for 23.50%,were mainly dis-tributed in the Kubuqi Desert and the southeastern part of the study area.(2)From 1990 to 2020,the habitat quali-ty in the Yellow River Basin in Inner Mongolia showed a trend of initial decrease and then a slight increase.Over the past 30 years,the area with degraded habitat quality,accounting for 11.97%,was mainly concentrated in the northern part of the study area and near the banks of the Yellow River.It is an area of cultivated land expansion and sandy land distribution,with significant human activity interference.Future research on ecological gover-nance and restoration should focus on this area.(3)Natural factors such as DEM,NDVI,and soil type are the main driving factors for spatial differentiation of habitat quality.The interaction of any two determining factors has greater explanatory power for the spatial differentiation of habitat quality than the corresponding single fac-tors.The study results provide reference and guidance for ecological environment protection and restoration re-search in the Yellow River Basin in Inner Mongolia.
