Responses of stable vegetation to drought accumulation timescales and time lags in the Weihe River Basin
Introduction This study aimed to distinguish drought accumulation timescale from response timing in stable vegetation in the Weihe River Basin. Methods We analyzed MODIS enhanced vegetation index (EVI) and ERA5-Drought standardized precipitation evapotranspiration index (SPEI) data for 2003–2024 on the native 0.25° dro...
