Euodia rutaecarpa is a traditional medicinal herb in China. The wild resources of E. rutaecarpa are scrace, and they are primarily sourced from cultivation. Predicting the potential suitable areas of E. rutaecarpa holds guiding significance for its cultivation and plant conservation. Using the MaxEnt (Maximum Entropy) and ArcGIS software, we predicted potential suitable habitat of E. rutaecarpa in China in the future (2041~2060, 2080~2100) through 318 occurrence records along with 14 environmental factors. The results indicated the following: (1) The model exhibited outstanding accuracy with AUC = 0.945 (>0.9), indicating that the model is constructed accurately and reliably. (2) The primary environmental factors influencing the distribution of E. rutaecarpa were average temperature of coldestquarter (Bio11), precipitation in the warmest quarter (Bio18), seasonal variation of temperature (Bio4), and aspect. Among these, average temperature of coldestquarter (Bio11) was the most influential environmental factor on E. rutaecarpa distribution. (3) Currently, E. rutaecarpa is widely distributed in China, with suitability areas located in provinces such as Jiangxi, Guangxi, Guizhou, and Hunan, covering 131.69 × 104 km2 (13.72% of China’s total land area). (4) Future climate change is projected to favor the distribution of E. rutaecarpa in China, with notable expansion in its potential total suitable areas and high suitability areas under different climate scenarios. These accurate predictions serve as a scientific references for the identification of suitable areas of E. rutaecarpa, and provide insights into both the conservation and sustainable utilization of its germplasm resources. %K 吴茱萸， %K 环境因子， %K 潜在适生区， %K MaxEnt， %K ArcGIS
