目的：本研究在药用植物全球产地生态适宜性区划信息系统（GMPGIS）的支持下，对鹅掌草全球生态适宜性进行了分析。方法：以地乌药材原植物鹅掌草道地产区、主产区和野生分布区的195个分布数据为基点，选取年均温、年均相对湿度、年均降水量、年均日照、土壤类型等7个生态指标作为主要影响因子。结果：鹅掌草全球生态相似度最大的区域主要分布在美国、俄罗斯、加拿大、中国、澳大利亚、哈萨克斯坦、墨西哥、阿根廷、伊朗、巴西、土耳其、乌克兰、南非等国。其中，鹅掌草在中国的生态适宜性地区主要包括陕西、贵州、甘肃、四川、湖北、重庆、浙江、云南、江苏、湖南等省区。结论：本研究表明了GMPGIS系统用于药用植物产地生态适宜性分析的科学性和重要性，并为地乌药材的引种以及合理规划生产布局提供了参考依据。

Global geographic information system for medicinal plant(GMPGIS)was developed and used to analyze the suitable producing area of A.flaccida based on 195 occurrence records in the main producing area of the species.Seven key factors referred to plant growth,such as annual mean temperature,annual precipitation,annual mean radiation,annual mean relative humidity and soil type,were chosen to be considered.The result showed that the suitable area for A.flaccida'growth mainly involved United States,Russia,Canada,China,Australia,Kazakhstan,Mexico,Argentina,Iran,Brazil,Turkey,Ukraine and South Africa,etc.What’s more,the ecological suitability regions of A.flaccida in China mainly covered Shanxi,Guizhou,Gansu,Sichuan,Hubei,Chongqing,Zhejiang,Yunnan,Jiangsu and Hunan provinces,etc.In conclusion,it was demonstrated that GMPGIS was scientific and valuable for the ecological suitability analysis of medicinal plants,which provided a reference for analyzing suitable producing areas and the introduction of A.flaccida.
