Introduction:
Predicting the biogeographic shifts of Helianthus tuberosus L. (H. tuberosus) under climate change is critical for its conservation and sustainable cultivation.
Methods:
We utilized occurrence records (n=295) and environmental variables to model current and future distributions across China via a hyperparameter-tuned MaxEnt framework under four Shared Socioeconomic Pathways (SSP126-SSP585, 2050s-2090s).
Results:
The model identified land cover (28.7%), vegetation index NDVI (23.7%), and minimum winter temperature (Bio6, 14.7%) as dominant drivers, collectively explaining 92.3% of distribution constraints. Currently, highly suitable habitats (6.03% of China's area) cluster in Yunnan, Guizhou, and central Jiangxi. Future projections indicate a 20.4% expansion of these habitats in northwest China due to winter warming, while southeastern coastal regions contract by 9.1% under extreme precipitation. The geographic centroid shifts 197- 238 km northwestward.
Discussion:
This shift highlights northwest China as a key climate refuge for H. tuberosus. These results prioritize conservation efforts and support strategic cultivation in climate-resilient zones.
