Maximum entropy model (Maxent) and geographic information system (GIS) were used to predict the global ecological suitable region of Codonopsis pilosula based on 129 distribution data and 37 ecological factors. The results showed that the total area of ecological suitable region was about 884.79×10 km, mainly in East Asia of the Northern Hemisphere, especially concentrated in China. The ecological suitable region in China with high suitable index was mainly in Shanxi, Shaanxi, Sichuan, southeast of Gansu, east of Tibet, southeast of Yunnan, and the northeast of Shandong. It was indicated that China had the most suitable region for C. pilosula cultivation. The main influence factors for the geographical distribution of C. pilosula were climate factors, and the first factor was temperature, the next one was precipitation, and the topography factors and soil factors followed. Mean annual temperature, precipitation seasonality, mean temperature of coldest quarter and precipitation of driest quarter were the most important factors for the distribution of C. pilosula.
基于129个分布数据和37个生态因子，利用最大熵模型（Maxent）和地理信息系统（GIS）预测党参的全球生态适宜区。结果表明，生态适宜区总面积约为884.79×10平方千米，主要位于北半球的东亚地区，尤其集中在中国。中国生态适宜指数较高的适宜区主要位于山西、陕西、四川、甘肃东南部、西藏东部、云南东南部以及山东东北部。这表明中国拥有党参种植的最适宜区域。党参地理分布的主要影响因素是气候因素，首要因素是温度，其次是降水，地形因素和土壤因素位列其后。年平均温度、降水季节性、最冷月平均温度和最干季降水量是党参分布的最重要因素。
