摘要

Habitat quality (HQ) is critical for the sustainable development of regional ecosystems and provides a theoretical basis for environmental protection and land use planning. The middle reaches of the Yellow River, characterized by abundant water resources, severe soil erosion, and high biodiversity conservation value, represent a vital ecological barrier for China’s environmental security. This study analyzes land use/land cover changes (LUCC) from 1992 to 2022 using a land use transfer matrix, evaluates HQ with the InVEST model, and identifies the primary driving factors and their complex interactions through the GeoDetector model. Spatial autocorrelation analysis (SAA), including Global Moran’s I (GMI), Local Moran’s I (LMI), and Getis-Ord Gi*, further uncovers spatial clustering and distribution patterns of HQ, revealing underlying ecological mechanisms. The results indicate that LUCC in the middle reaches of the Yellow River has undergone significant transformations: urbanization and agricultural expansion have exerted negative impacts on HQ, while ecological restoration policies have substantially improved HQ in certain areas. GeoDetector analysis highlights economic development and LUCC as the dominant drivers of HQ, with significant synergistic interactions among factors. SAA confirms the clustering characteristics of HQ, providing robust support for the formulation of more targeted and effective environmental protection strategies. This study recommends strict implementation of conservation boundaries, curbing urban land expansion, optimizing ecological compensation mechanisms, and promoting ecological restoration policies, such as converting farmland to forests or grasslands, to enhance HQ in the region.
