Abstract: Based on sampling sites which covering both traditional and current major producing regions, the suitable ecological region and potential artificial cultivation area of Nervilia fordii with global geographic information system for medicinal plant (GMPGIS) was predicted. The results indicated that the suitable ecological regions for N. fordii cultivation in the world were China, Brazil, Vietnam and Laos and other seven countries or regions. China was the most suitable ecological area for N. fordii and the optimum area was 406 980.1 km2，accounting for 69% of the total area in the globe. Furthermore, fourteen potential suitable producing provinces in China were predicted, including Guangxi, Guangdong, Fujian, Hainan, Yunnan, ect. The ecological suitability of N. fordii was explored for its further artificial cultivation.

Key words: Nervilia fordii, GMPGIS, ecological suitability

摘要： 搜集青天葵Nervilia fordii主产区及野生分布区的分布样点，应用药用植物全球产地生态适宜性区划信息系统(GMPGIS)对南药青天葵进行全球产地生态适宜性分析。对青天葵各生态因子进行聚类分析，得到青天葵在全球范围的生态适宜区和潜在的人工栽培区。中国、巴西、越南、老挝等11个国家和地区境内皆有青天葵生长的适宜区；其中适宜区面积最大的为中国，总面积为406 980.1 km2，占全部面积的69%；青天葵在中国的适宜分布区主要位于广西、广东、福建、海南、云南等省(区)。GMPGIS分析结果为青天葵的人工栽培提供科学依据，有助于保护青天葵药用资源，以期促进稀缺药用资源青天葵的区划研究和人工栽培。
