Glycyrrhiza inflata Batalin is an important medical plant of the genus . It one key protected plants in China, distributed desert areas southern Xinjiang and Dunhuang Gansu Province. has a strong resistance to drought, heat, salt stresses, plays pivotal role sand fixtion areas. In this study, based on 157 valid distribution records eight environmental factors including climate altitude, potential area G. last glacial maximum, middle Holocen, modern, future (2050) times China were predicted, using optimized MaxEnt model ArcGis 10.2 software. The results showed that predicted was highly consistent with current range, under receiver operating characteristic (AUC) curve 0.986, indicating prediction performance excellent. climatic affecting precipitation December average annual precipitation. Meanwhile, suitable modern 1,831,026 km 2 , mainly Turpan-Hami Basin, Tarim Province, Lop Nur Town as center. 2050, for will be 1,808,090 250,970 which suitable, 150,600 smaller than times, reduction rate 60.0%. Therefore, there trend great From glaciation maximum Holocene, geographical center shifted southwest margin Kumtag Desert, Xinjiang, then later continued shift southwest. This study provide basis understanding origin evolution developing conservation strategies minimize impacts environment change, utilizing resource.
