Nonlinear and lagged associations between active-layer thickness and vegetation greenness in the source reach of the Yangtze River basin from 1990 to 2024

Permafrost degradation can alter alpine vegetation through changing hydrothermal conditions, but nonlinear relationships between active-layer thickness (ALT) and vegetation and their temporal lags remain poorly quantified on the Qinghai–Tibet Plateau. We integrated a cross-sensor...
