Vulnerability assessment and analysis of cryosphere changes in the Western Sichuan Plateau

open access: yesArctic, Antarctic, and Alpine Research
A vulnerability assessment model and indicator system for the changes in the cryosphere in the Western Sichuan Plateau are constructed based on the “exposure–sensitivity–adaptive capacity” framework. The model aims to capture the multiple characteristics
