摘　　要：独一味是青藏高原特有的重要药用植物,因青藏高原对气候变化的高度敏感性,易引起独一味适生范围受气候变化强烈的影响。准确量化物种对气候变化的脆弱性对于评估物种灭绝风险和制定有效的保护策略至关重要。因此,本研究基于α-shape方法确定的独一味栖息地和基于2种“社会共享经济途径(shared socioeconomic pathways,SSPs)”发展前景(SSP126和SSP585)及3种大气环流模型(CMCC-ESM2、HadGEM3-GC31-LL、IPSL-CM6A-LR)评估得到的2个不同时期(2041~2060、2081~2100年)的未来气候变化数据,采用气候生态位因子分析法,通过综合独一味对平均日温差、温度季节性、最暖季平均温、最干月降水量和最暖季降水量5个气候变量的敏感性和暴露性指标,分析了独一味对气候变化的脆弱性。结果发现,独一味在最暖季降水量上的脆弱性最高,在其栖息地范围内的脆弱性总体表现为南高北低、西高东低的空间格局,且其脆弱性在SSP585情景下高于SSP126情景。不同大气环流模型的气候数据对结果存在一定影响,可通过数据集成方法降低其不确定性。受气候变化影响,未来独一味在低海拔区域如雅鲁藏布江、易贡藏布、察隅河、脚木足河等河滩地的生存压力加剧,而高海拔地带如唐古拉山脉东部、横断山脉北部和秦岭西部地区中高度风化的碎石滩或石质高山草甸可能成为其避难所,需要重点关注和加强对这些脆弱区和关键区独一味资源的保护和管理。Lamiophlomis rotata is an important medicinal plant species endemic to the Tibetan Plateau,which is prone to strong climate change impacts on its habitable range due to the high sensitivity of the Tibetan Plateau to climate change.Accurate quantification of species vulnerability to climate change is essential for assessing species extinction risk and developing effective conservation strategies.Therefore,we carried out theα-shape analysis to determine the habitat of L.rotata.We then carried out the climate-niche factor analysis(CNFA)to assess the vulnerability of L.rotata to climate change based on five climate variables(i.e.,mean diurnal range,temperature seasonality,mean temperature of warmest quarter,precipitation of driest month and precipitation of warmest quarter)in the context of two shared socioeconomic pathways(i.e.,SSP126 and SSP585)and three global climate models(CMCC-ESM2:Centro Euro-Mediterraneo sui Cambiamenti Climatici-Earth System Model version 2;HadGEM3-GC31-LL:Hadley Global Environment Model version 3-Global Coupled configuration 3.1;IPSLCM6A-LR:Institut Pierre Simon Laplace-Climate Model version 6)during two different periods(2041-2060 and 2081-2100).The vulnerability of L.rotata to climate change was calculated by integrating the sensitivity and exposure indices of L.rotata to five climate variables.The results showed that L.rotata had the highest vulnerability to the precipitation of warmest quarter.Its vulnerability within its habitat range generally showed a spatial pattern of high value in the southern region and low in the northern region,high in the western region and low in the eastern region.In general,the vulnerability of L.rotata under the SSP585 scenario was higher than that under the SSP126 scenario.The climate data of different global climate models have some influence on the results,while the resulted uncertainty can be reduced by data integration methods.As a result of climate change,the pressure on the survival of L.rotata in the future will be intensified in the low-altitude
