Abstract

Desertification sensitivity in semi-arid urbanizing regions remains a critical challenge for sustainable land management. This study analyzes the spatiotemporal dynamics (2018–2022) of desertification sensitivity in the Beijing–Tianjin–Hebei core region using the Normalized Difference Vegetation Index (NDVI), soil texture, the Digital Elevation Model (DEM), and nighttime light data. Using a GIS-based model, we found a decline in overall desertification sensitivity, with vegetation degradation (post-2020) emerging as a key factor. Key recommendations include optimizing urban spatial patterns via ecological red lines, prioritizing vegetation restoration in high-sensitivity zones, and establishing dynamic remote sensing-based monitoring systems. These strategies aim to coordinate urban growth with ecological resilience, offering actionable pathways for semi-arid regions facing similar pressures. Future work should integrate socioeconomic drivers to refine adaptive governance frameworks.
