The distribution of suitable habitats for medicinal plants is affected by climate, soil, land use, and other factors. , an important traditional Chinese medicinal resource in Xinjiang, includes (Royle) I. M. Johnst. and Bunge and is at risk of over-exploitation. This study predicted suitable planting areas by integrating habitat and phytochemical suitability using the MaxEnt model and ArcGIS. The AUC values for and were 0.977 and 0.952, with TSS values of 0.829 and 0.725, respectively, validating the high accuracy of the prediction model. Under the current scenario, the areas of suitable habitats for and were 108,914 and 176,445 km, mainly distributed along the main mountains in Xinjiang. Under future climate scenarios, the suitable habitat area of increased by 11-18%, except in the ssp126-2090s scenario, while the suitable habitat area of area decreased by 3-18%. Both species were influenced by land use/land cover and soil available nitrogen content; additionally, was affected by the precipitation in the driest month, and by the mean diurnal range. The content of secondary metabolites was positively correlated with habitat suitability, with soil factors contributing 35.25% to the total secondary metabolite content. Their suitable habitats predominantly occur in grasslands (42-82%). As habitat and phytochemical suitability distributions aligned, the eastern and western sides of the northern Kunlun Mountain Pass emerged as key areas for cultivation. This research can provide a scientific foundation for selecting optimal planting regions for the two species.
药用植物适宜生境的分布受气候、土壤、土地利用等因素影响。新疆一种重要的传统中药资源包括新疆阿魏（Ferula sinkiangensis (K. M. Shen) X. T. Guan & R. H. Shan）和新疆阿魏（Ferula fukanensis K. M. Shen），面临过度开发风险。本研究利用MaxEnt模型和ArcGIS整合生境与植物化学适宜性来预测适宜种植区域。新疆阿魏（Ferula sinkiangensis (K. M. Shen) X. T. Guan & R. H. Shan）和新疆阿魏（Ferula fukanensis K. M. Shen）的AUC值分别为0.977和0.952，TSS值分别为0.829和0.725，验证了预测模型的高精度。在当前情景下，新疆阿魏（Ferula sinkiangensis (K. M. Shen) X. T. Guan & R. H. Shan）和新疆阿魏（Ferula fukanensis K. M. Shen）适宜生境面积分别为108,914平方千米和176,445平方千米，主要分布在新疆的主要山脉沿线。在未来气候情景下，除ssp126 - 2090年代情景外，新疆阿魏（Ferula sinkiangensis (K. M. Shen) X. T. Guan & R. H. Shan）适宜生境面积增加11% - 18%，而新疆阿魏（Ferula fukanensis K. M. Shen）适宜生境面积减少3% - 18%。两个物种均受土地利用/土地覆盖和土壤有效氮含量影响；此外，新疆阿魏（Ferula sinkiangensis (K. M. Shen) X. T. Guan & R. H. Shan）受最干旱月份降水量影响，新疆阿魏（Ferula fukanensis K. M. Shen）受日较差影响。次生代谢产物含量与生境适宜性呈正相关，土壤因素对次生代谢产物总含量贡献35.25%。它们的适宜生境主要出现在草地（42% - 82%）。由于生境和植物化学适宜性分布一致，昆仑山口北部的东西两侧成为关键种植区域。本研究可为这两种阿魏属植物选择最佳种植区域提供科学依据。
