Magnolia biondii Pampan., a traditional Chinese medicinal plant, holds significant ornamental and medicinal value.We used the MaxEnt model and ArcGIS software to study the potential habitats of M. biondii in China.The results showed that the model exhibited outstanding accuracy, boasting an average area under the receiver-operator curve (AUC) of 0.955.The distribution of M. biondii was primarily influenced by three key environmental factors: min temperature of coldest month (Bio06), precipitation of warmest quarter (Bio18), and precipitation of coldest quarter (Bio19).Currently, M. biondii habitats are concentrated in East, Central, and Southwest China, covering 107.95 × 10 4 km 2 .Notably, Hubei, Henan, and Shandong host the majority of highly suitable areas.Future global warming will have a positive impact on the potential distribution area of M. biondii, and its distribution center has a tendency to migrate to higher latitudes.These findings contribute to the theoretical understanding of plant resources and provide insights into the habitat conservation of M. biondii.
