are perennial herbaceous plants of the Liliaceae family with high ornamental, nutritional, and medicinal value. However, critical knowledge gaps remain regarding the following: (1) the fine-scale habitat preferences of ; (2) the key ecological drivers influencing their growth and distribution. The MaxEnt software 3.4.1 was used to simulate the current and future suitable habitats of , evaluate the impacts of environmental changes on its distribution, and determine the distribution changes under climate change scenarios. The AUC value of the model used in the current study was >0.98, which indicates that the model had good accuracy. The results show that as a typical understory herb, precipitation in the warmest quarter (bio18) and temperature seasonality (bio04) are the main factors affecting the distribution of . In addition, and var. are also affected by slope and human activity. Under the SSP126, SSP245, and SSP585 climate scenarios, the suitable habitat areas of and showed an increasing trend. The suitable habitat area of var. increased under the SSP126 climate scenario; however, it substantially declined in SSP245 and SSP585 scenarios. The distribution area of shifted to higher latitudes. The centroid of shifted more than 5 degrees of latitude during SSP585 2081s, while the centroid of and var. did not shift more than 2 degrees of latitude. In addition, the centroid longitudes of and var. shifted westward under the three climate scenarios. There is ecological niche differentiation among and others, whilst and var. have overlapping ecological niches. In the future, we will strengthen the protection of wild resources in accordance with environmental factors and suitable habitats for .
