【Objective】 This study investigated distribution patterns and changes of suitable habitats for Sinowilsonia henryi Hemsi.under different climate change scenarios to predict the past and future suitable habitats.【Method】 Maximum entropy (MaxEnt) model was employed to predict the suitable habitats of Sinowilsonia henryi Hemsi.in different decades based on the climate change data of current,last interglacial (LIG),last glacial maximum (LGM),2050s and 2080s.【Result】 The MaxEnt model was accurate for predicting distribution of Sinowilsonia henryi Hemsi.The suitable habitats of S.henryi were mainly influenced by 7 bioclimatic variables,including mean temperature of driest quarters,precipitation of warmest quarters,mean temperature of coldest quarters,precipitation of driest months,mean temperature of wettest quarters,isothermality and precipitation of coldest quarters.The suitable habitat area of S.henryi in LIG was 1.65 times as large as that in current,but the distribution was more southward.The suitable habitat of S.henryi shrunk greatly in LGM,which was 4.4% of that in current,and the distribution scattered in Mts.Bashan and valleys along upper reach of Hanjiang River.The suitable habitat of S.henryi would expand during 2050s and 2080s,with total area welling to 19 and 13 times as large as that in current,respectively.【Conclusion】 S.henryi was sensitive to climate change.The suitable habitats varied greatly under different climate change scenarios,and would expand with the anticipated wormer climate in the 21st century.
