Landslide Susceptibility Modeling Constrained by Multi-Scale Polygon Sampling and InSAR Deformation for High-Relief Mountainous Areas: A Case Study in the Upper Jinsha River, Southwest China
The Upper Jinsha River region on the southeastern Tibetan Plateau is characterized by intense tectonic activity, extreme topographic relief, and widespread large-scale landslides, which pose significant threats to communities, transportation networks and major infrastructure. However, accurate landslide susceptibility...
