Understanding grassland stability under severe drought is essential for promoting sustainable management in Northern China and Tibetan Plateau (NCTP). However, the differences in stability among various grassland biomes in response to severe drought remain unknown in the NCTP. Therefore, we quantified the temporal stability, drought resistance, and drought resilience of various grassland biomes in the NCTP. Our findings indicated that alpine grasslands exhibited higher stability compared to temperate grasslands, due to their greater drought resistance. This was attributed to the higher biodiversity, precipitation and radiation, and lower temperatures in alpine grasslands, which reduce drought exposure and sensitivity. Drought resilience was similar across grassland biomes, particularly in temperate regions. CMIP6-based projections indicated that future changes in the stability of grasslands in the NCTP exhibited an increasing trend. These findings offer a scientific reference for assessing the impacts of climate change on vegetation growth and carbon cycling in the NCTP.
