Abstract:
Objective To predict the potential suitable habitats of Scutellaria barbata D.Don across China;To provide a theoretical basis for its artificial cultivation and standardized planting practices.Methods Distribution data were collected from 186 sample sites,combined with data from 90 environmental factors,and the MaxEnt model and ArcGIS 10.8.1 software were used to screen the main environmental factors affecting the distribution of Scutellaria barbata D.Don and to analyse and predict the distribution of Scutellaria barbata D.Don suitability zones in China.Results The dominant environmental factors affecting the distribution of Scutellaria barbata D.Don were the driest month precipitation,vegetation subclasses,minimum temperature in September,precipitation in October,and soil base saturation.The high-suitability zones for Scutellaria barbata D.Don are primarily concentrated in the northern Guangxi Zhuang Autonomous Region and its bordering areas with Hunan Province,the central of Guangdong Province,and the border regions between Jiangxi Province and Fujian Province.Conclusion The predicted results of this study can provide a reference for the selection of sites for artificial cultivation and standardized planting of Scutellaria barbata D.Don in southeast China and eastern southwest China(e.g.Zhejiang Province,Jiangxi Province,Sichuan Province,etc.),and provide a reference for the sustainable utilization of Scutellaria barbata D.Don medicinal resources.
