Abstract: Based on the geographical distribution records of 184 Schisandra sphenanthera, 129 Schisandra chinensis and 23 environmental factors, the maximum entropy (MaxEnt) ecological niche model was used to predict the potential suitable distribution areas of Schisandra sphenanthera and Schisandra chinensis. The main environmental factors restricting their geographical distribution were evaluated. The results showed that the area under the curve (AUC) of the training set and verification set of MaxEnt model of Schisandra chinensis and Schisandra sphenanthera were both greater than 0.90, and the prediction results of established models were accurate. The best habitats of Schisandra chinensis were mainly distributed in Changbai Mountain area of Liaoning Province and Jilin Province and Beijing City. The best habitats of Schisandra sphenanthera mainly distributed in Qinba Mountain area, Wuling Mountain Range of Hunan Province, Chenzhou City, Zhuzhou City and Hengyang City, Jinhua City of Zhejiang Province and other areas. The important environmental factors limiting the growth of Schisandra chinensis were precipitation in the wettest month, maximum temperature in the hottest month, soil pH, average precipitation in the warmest season, average precipitation in the coldest season and the monthly mean temperature difference between day and night. The environmental factors limiting the distribution of Schisandra sphenanthera were the lowest temperature in the coldest month, the average annual precipitation, the variance of temperature change and the variance of precipitation change. The potentially suitable areas of Schisandra sphenanthera and Schisandra chinensis showed regional distribution.
