深红龙胆具有很高的观赏价值和药用价值，但因其生境特殊，引种栽培非常困难，目前对其利用全部为野生资源。本研究利用MaxEnt和ArcGIS软件对深红龙胆的适生区进行生态位模拟。结果表明，深红龙胆的最佳适生区主要集中在贵州、四川、重庆等地，适生区几乎覆盖华中、华南及华东的大部分省市。对环境变量进行刀切法发现，在19个环境变量中，最冷季平均温度对分布模型的贡献率达50.2％，最热季平均温度、最热季降雨量、最湿季降雨量、最湿季平均温度和极端最高温5个环境变量对分布模型的贡献率不超过0.1％。研究结果将为深红龙胆引种、驯化、栽培及其他相关研究提供参考。

Gentiana rubicunda has very important ornamental and medicinal value.Since its introduction and cul-tivation are difficult because of its special habitat , it could only be used from wild resources .MaxEnt niche model-ing and ArcGIS software were applied to predict the potential distribution of G.rubicunda.The results showed that G.rubicunda is mainly distributed in Guizhou, Sichuan province and Chongqing municipality, and could survive in east, center and south of China.The Jackknife analyses of environmental variable showed that the MaxEnt contri-bution rate of mean temperature of coldest quarter reached 50.2 %.However, contribution of precipitation of the wettest season , max temperature of the warmest month , mean temperature of the warmest season , precipitation of the warmest season and mean temperature of the wettest season was no more than 0.1 %.The ecological niche modeling of G.rubicunda could provide a fundamental guidance for introduction and cultivation of this species.
