     abstract = "{Accurately removing seasonal variations in GPS vertical displacements
        caused by environmental loading is critical for accurate crustal
        movement analysis. Firstly, this study compares GPS station
        displacements with GRACE-derived nonlinear environmental loading
        deformations using wavelet transform analysis, revealing
        consistent trends (correlation coefficient 0.64), with most
        stations consistent annual periodicity that confirms
        environmental loading as the dominant factor. Subsequently, the
        comparative analysis of Singular Spectrum Analysis (SSA) and
        Least Squares Fitting for annual signal extraction demonstrated
        that SSA achieved higher correlation with loading deformations
        and lower weighted root mean square residuals, confirming its
        superior performance for annual signal isolation. Furthermore,
        the SSA method was extracted annual environmental loading
        signals, demonstrating their superior correction effectiveness
        in most cases through improved correlation coefficients and WRMS
        reduction, while nonlinear signals showed better performance in
        specific cases. Finally, combining GRACE-derived nonlinear and
        annual loading deformation signals to correct station coordinate
        variations. It was found that the correction effect was
        improved, mainly affected the station noise through the WN + PL
        model, and the reduction of speed uncertainty is further
        improved.}",
