摘　　要：目的:重齿当归是我国重要的药用草本植物,但其在中国的潜在分布规律尚不明确。本研究旨在探讨重齿当归在中国当前的潜在空间分布特征及其对未来气候变化的响应模式。方法:本研究运用MaxEnt模型和生态位理论进行预测和分析。结果:降水量、海拔和温度是影响重齿当归分布的主要环境因素。当前,重齿当归主要分布在中国中部和东南部,覆盖范围广泛。然而,未来气候变化情景下,其适宜生长区域可能缩小。结论:未来气候变化对重齿当归的地理分布产生深远影响,未来其适宜生长区域将向西北迁移,但其道地产区可能维持不变。本研究结果对于提升重齿当归的经济和生态效益具有重要意义。Objective:Angelica biserrata(Apiaceae)was an important medicinal herb in China.However,its potential distribution patterns in the country remained unclear.This study aimed to explore the current potential spatial distribution characteristics of A.biserrata in China and its response patterns to future climate change.Methods:The MaxEnt model,combined with niche theory,was employed for prediction and analysis.Results:Key environmental factors influencing the distribution included precipitation,altitude,and temperature.The species was primarily distributed in central and southeastern China,showing a wide range.Under future climate scenarios,the area of suitable habitats would be projected to decrease.Conclusion:Future climate change would have a profound impact on the geographical distribution of A.biserrata.Its suitable growth areas would shift northwestward,while its geo-authentic producing areas might remain unchanged.The research results are of great significance for improving the economic and ecological benefits of A.biserrata.The research results were of great significance for improving the economic and ecological benefits of A.biserrata.
