摘要

The Tibetan grassland is the principal ecosystem in a high-altitude, ecologically fragile region, providing vital services for biodiversity and local livelihoods. Constructive grass species play a pivotal role in maintaining the structure and function of grassland ecosystems. In this study, we constructed a comprehensive dataset of the spatial distribution of all constructive grass species (44) in Tibetan grasslands under current (2024) and four future (2060) climate scenarios by leveraging species distribution models and high-resolution ecological data. Our dataset encompasses each individual constructive grass species habitat distribution, including expansion, contraction, and stability. This dataset will be applied to climate-change impact assessment on individual species, grassland-type shift projection, and multi-stressor ecosystem-dynamics evaluation. It is essential for supporting grassland management, biodiversity conservation, and livestock production in high-altitude grassland ecosystems.
