Through the research of ecological suitability,yield,and quality regionalization of Gastrodia elata in Ningqiang County,this paper provided a reference for industry planning of G.elata in Ningqiang County.Methods:Based on the MaxEnt model and combined with the origin investigation,literature information collection,sample collection and content measurement,the ecological environmental factors affecting the yield and quality of G.elata were analyzed,and the relationship model between the active components and environmental factors was established.The quality and production regionalization of G.elata were studied by using geographic information system technology(ArcGIS).The research methods of production regionalization of G.elata on small scale(county) were summarized.Results:The collected 89 ecological factors affecting G.elata were screened,and 13 ecological factors were finally selected for further analysis.The environmental factors affecting G.elata were topographic factor(43.2%)>climate factor(27.9%)>soil factor(22.3%)>vegetation factor(6.5%) in order of contribution rate.The ecological high suitable areas of Ningqiang G.elata were mainly distributed in the central and eastern part of the county,the southern part and the northern part of the county.The suitable area with high yield was mainly in the eastern part of the county.High-quality suitable areas were mainly distributed in the western,northern and southern parts of the county,the extract content of G.elata was relatively low in the high altitude area,while the content of parishin E was relatively high in the flat terrain area.The spatial distribution of parishin B,C and Gastrodin contents was consistent.Conclusion:Climate and soil were the main environmental factors affecting the distribution of G.elata in Ningqiang County,Shaanxi Province.The distribution law of suitable area was different between the quality regionalization and the yield regionalization of G.elata.
