摘　　要：目的通过对线叶龙胆药材的潜在分布区的分析及品质区划的研究,为指导藏药线叶龙胆资源保护、可持续利用与野生驯化提供理论依据。方法通过查询网络标本馆和野外实地调查,采用最大熵(MaxEnt)模型和地理信息系统软件ArcGIS10.2对我国线叶龙胆进行生态适宜性区划分析,应用SPSS25.0软件构建指标成分与环境因子之间的关系模型,结合ArcGIS软件空间分析技术,形成线叶龙胆药材品质区划。结果影响线叶龙胆生态适宜性的主要环境因子是海拔、5月份降水量、4月份降水量、12月份降水量和昼夜温差月均值。线叶龙胆最适宜生长区主要集中在甘肃、四川和青海交界处,西藏部分地区及四川部分地区。西藏南部、四川西南部线叶龙胆药材综合品质较高。结论本研究结果可为线叶龙胆的生产布局及质量评价提供参考。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.
