     abstract = "{The Tibetan Plateau represents one of the most seismically active
        regions globally. The construction of the Xinjiang-Tibet Railway
        is profoundly affected by crustal deformation and geological
        hazards. To address the urgent need for regional crustal
        stability and risk assessment in this region, this study
        integrates large-scale observations from the Gravity Recovery
        and Climate Experiment (GRACE) satellite and GNSS data to
        extract vertical crustal deformation information along the
        railway route, along with multi-source geological, seismic, and
        meteorological data. Additionally, terrestrial water storage
        changes are a critical factor influencing stability. A multi-
        factor weighted overlay method is employed, incorporating ten
        evaluation indicators to assess crustal stability along the
        railway and develop a multidimensional framework for monitoring
        and evaluating regional crustal stability. The study also
        extends the research area by 40 km, 80 km, and 170 km. The
        assessment results reveal that Equivalent Water Height (EWH)
        variations, derived from GRACE satellite gravimetry, demonstrate
        relatively stable interannual fluctuations across the study
        region, while Terrestrial Water Storage Anomalies (TWSA) exhibit
        a modest declining trend, which amplifies with increasing
        spatial scale. Integrating GRACE satellite gravimetry and GNSS-
        derived deformation metrics, this study evaluates crustal
        stability indices and categorizes the study area into stable,
        moderately stable, and moderately unstable zones, highlighting
        spatial variations in regional tectonic stability. The northern
        section of the Xinjiang-Tibet Railway predominantly features
        stable to moderately stable conditions. In contrast, the
        southern section shows moderately unstable to unstable
        conditions, with instability expanding as the scope of analysis
        broadens. This evaluation framework offers critical insights and
        scientific support for infrastructure development and disaster
        mitigation strategies.}",
