Abstract:
Objective To predict the potential suitable distribution areas of Polygala tenuifolia in Shanxi Province;To provide basis for the excavation and utilization of existing resources and the selection of cultivation areas of Polygala tenuifolia.Methods The distribution information of 1 102 Polygona tenuifolia samples was collected(Among them,there were 1 060 samples of Polygala tenuifolia Willd.,42 samples of Polygala sibirica L.).Combined with the 55 ecological factor data,the MaxEnt model and ArcGIS were applied to analyze the main ecological factors affecting the distribution of Polygala tenuifolia.Results The dominant ecological factors for the suitability distribution of Polygala tenuifolia were vegetation type,precipitation,temperature,etc.The potential suitable distribution areas of Polygala tenuifolia in Shanxi Province were mainly concentrated in Linfen,Lvliang,Taiyuan,Changzhi,Jinzhong,southeastern of Yuncheng,northwestern of Xinzhou,southwestern of Shuozhou,etc.Conclusion The ecological suitability zoning map of Polygala tenuifolia Willd.and Polygala sibirica L.was obtained,which can provide reference for the reasonable selection of planting areas and standardized production of Polygala tenuifolia in Shanxi Province.
