摘　　要：研究三七的生态适宜性区划及其生态特征,为三七人工引种栽培和区域发展提供参考。通过检索全球生物多样性信息网、中国数字植物标本馆和相关文献收集全国67个三七分布点,利用最大信息熵模型(MaxEnt)和GIS技术对三七进行适宜性区划。MaxEnt预测结果表明,三七可能的生态适宜区分布在云南、广西、广东、贵州、海南、四川、福建和重庆。生态相似度最高区域(大于60%)主要位于云南、广西、广东和贵州部分地区,面积约为89 571.3 km^2;生态相似度次高区域(40%~60%)主要分布在云南、广西、广东、贵州、海南和四川省,面积约为155 172 km^2;生态相似度为20%~40%的区域面积约为329 952.8 km^2,主要分布在云南、广西、广东、贵州、海南、四川、福建和重庆。影响三七地理分布的主要生态因子为最暖季降水量、气温的季节性、海拔、等温性、降水的季节性、月均温范围、最干月降水量、土壤体积密度和土壤质地。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
