This paper is aimed to clarify the distribution of Codonopsis Radix in China and search the main ecological factors that affect the suitability distribution. Through literature reading, National Specimen Information Infrastructure researching, field investigation and general survey of Chinese medicine resources, the distribution information was acquired. The MaxEnt model and ArcGIS technology were applied to analyze the main environmental factors influencing the suitability of Codonopsis Radix with integrated 55 environmental factors. The results showed the precipitation and altitude were the major factors impacting the ecology suitable of Codonopsis Radix. The ecological suitable region of C. pilosula was mainly concentrated in south Gansu, Shanxi, Shanxi, Ningxia and, and the ecological suitable region of C. pilosula var. modesta was mainly concentrated in south Gansu, northwest Guizhou, northeast Sichuan, and the ecological suitable region of C. tangshen was mainly concentrated in west Hubei, east Chongqing, middle Sichuan. Combined with the investigation and cultivation of Codonopsis Radix distribution information, the results of ecological suitability of Codonopsis Radix were verified. The ecological suitability distribution result of Codonopsis Radix was consistent with each species actual distribution, which could provide scientific basis for carrying out the rational cultivation of Codonopsis Radix.
本文旨在阐明党参在中国的分布情况，并探寻影响其适宜分布的主要生态因子。通过文献阅读、国家标本信息基础设施研究、实地调查以及全国中药资源普查，获取了分布信息。运用最大熵模型（MaxEnt）和ArcGIS技术，结合55个环境因子，分析影响党参适宜性的主要环境因子。结果表明，降水和海拔是影响党参生态适宜性的主要因素。党参的生态适宜区主要集中在甘肃南部、陕西、山西、宁夏等地；素花党参的生态适宜区主要集中在甘肃南部、贵州西北部、四川东北部；川党参的生态适宜区主要集中在湖北西部、重庆东部、四川中部。结合党参分布信息的调查与栽培情况，对党参生态适宜性结果进行了验证。党参生态适宜性分布结果与各物种实际分布一致，可为党参的合理栽培提供科学依据。
