Genus Asarum contains several plant species that are mostly used as precious drug resources. In this study, 126 distribution records of 3 Asarum species and relevant 28 environmental factors data were collected, then a geographical distribution model of the genus medicinal plants in China was made by Maxent and the ArcGIS spatial analysis technique. The results showed that the 3 Asarum species have a wide potential distribution region. High suitable region and suitable region were 3125km2 and 276042km2 respectively. Among the environmental factors, 3 precipitation factors (annual precipitation, precipitations in the most dry season and the most warm season) are the main ones that can affect the distribution of the 3 Asarum medicinal plants. This study can provide a useful reference for the collection and cultivation of Asarum medicinal plants.

Key words: Asarum, Prediction of potential distribution, Maximum entropy model (Maxent)
