Abstract: 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 884.79×104 km2, 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.
