Glaciers are essential freshwater resources in arid regions, and accurately delineating the boundaries of debris-covered glaciers is critical in assessing water resources. Traditional glacier inventory data often struggle to differentiate the transitional zones between active ice and rock glaciers due to spectral confusion and topographic complexity. This leads to uncertainties in determining glacier extents and evaluating water resources. This study focuses on the Kunjiersu glacier in the western Pamir Plateau, employing a multi-source remote sensing approach that integrates synthetic aperture radar and optical techniques. Utilizing Sentinel-1A offsettracking technology and TanDEM geodetic methods, we derive glacier surface velocity fields and elevation changes, complemented by visual interpretation of Landsat-8 optical imagery for boundary delineation while analyzing climatic influences. Key findings reveal the following. The central glacier section (3.8-5.8 km from the terminus) consistently shows activity, with peak winter velocities reaching 0.2 m·d-1 and significant mass exchange; from 2013 to 2020, this section experienced ablation, but post-2020 data indicate cumulative thickening of 7.06±6.05 m, confirming ongoing active ice flow. Revised Randolph glacier inventory data suggest a 2.8 km2 underestimation of the original area of the Kunjiersu glacier. This proposed multi-source collaborative methodology offers theoretical support for identifying glacier activity and updating boundaries of debris-covered glaciers, providing critical insights for dynamic water resource assessment in arid regions and for maintaining global glacier databases.
