RESUMEN
The ecology suitability and ecological characteristics of Panax notoginseng (Burk.) F. H. Chen were studied to provide a reference for its artificial introduction and cultivation. The maximum entropy model (MaxEnt) and geographic information system (GIS) were used to investigate the global ecology suitability regions for Panax notoginseng (Burk.) F. H. Chen based on its 67 distribution points collected from global biodiversity information facility (GBIF), Chinese virtual herbarium (CVH) and the related references. The results showed that the possible ecological suitable regions of Panax notoginseng (Burk.) F. H. Chen were located in Yunnan, Guangxi, Guangdong, Guizhou, Hainan, Sichuan, Fujian and Chongqing provinces. The areas with ecological similarity higher than 60% were about 89 571.3 square kilometers in total, mainly distributing in Yu nnan and Guangxi provinces and small portion was located in Guangdong and Guizhou provinces. The areas with ecological similarity between 40% and 60% were about 155 172 square kilometers, mainly in Yunnan, Guangxi, Guangdong, Guizhou, Hainan, Sichuan provinces. The distribution areas were about 329 952.8 square
