Abstract:
Objective To analyze the potential distribution and quality zoning of Gentiana farreri Balf.f.;To provide a theoretical basis for the conservation,sustainable utilization,and domestication of this Tibetan medicine resource.Methods The MaxEnt model and geographic information system software ArcGIS 10.2 were used to conduct ecological suitability zoning of Gentiana farreri Balf.f.in China through searching online specimen libraries and field investigations.SPSS25.0 software was used to construct a relationship model between indicator components and ecological factors,combined with ArcGIS software spatial analysis technology,to form a quality zoning of Gentiana farreri Balf.f.medicinal material.Results The primary environmental factors influencing the ecological suitability of Gentiana farreri Balf.f.were altitude,precipitation in May,April and December,and the mean monthly diurnal temperature range.The most suitable growth areas for Gentiana farreri Balf.f.were predominantly found at the junction of Gansu,Sichuan and Qinghai provinces,certain parts of Tibet,and selected regions of Sichuan.The southern part of Tibet and the southwestern part of Sichuan were identified as having higher comprehensive quality of Gentiana farreri Balf.f.medicinal materials.Conclusion The findings of this study can serve as a reference for the production planning and quality assessment of Gentiana farreri Balf.f.
