The alpine steppe has an important place in ecosystems, and its distribution pattern is strongly influenced by climate change. In this study, we used “biomod2” “FragStats 4.2” to calculate the migration trends habitat fragmentation of three S. purpurea steppes on western Tibetan Plateau. results study show that Stipa purpurea-Ceratoides compacta steppe, purpurea-Carex moorcroftii montis-everestii are climate, while other variables have less impact. Their main influence factors annual precipitation (Bio12), warmest quarter (Bio18), coldest (Bio19), respectively. effects carbon emissions suitable habitats all significant future scenarios. Continued increases will lead a continuous reduction their areas. These communities bounded 33° N. South boundary, mountain ranges tendency migrate higher elevations southward direction. North northward Climate change reduces community aggregation, leading gradual fragmentation. findings provide scientific basis for conservation Plateau, thereby contributing improvement ecosystem stability species diversity.
