摘要

Climate change not only affects the geographical distribution patterns of plants but also significantly impacts the types and quantities of their secondary metabolites, thereby influencing the ecological and economic value of medicinal plants. Tetradium ruticarpum, a traditional Chinese medicinal material, lacks research on coping with climate challenges. This study utilized the MaxEnt model and ArcGIS software for the first time to predict and analyze the various periods’ suitable habitats for T. ruticarpum in China. The results indicated that the precipitation of the precipitation of driest month (bio14), the mean diurnal range (bio2), the precipitation of warmest quarter (bio18), and the temperature seasonality (bio4) were the primary environmental factors affecting the distribution of T. ruticarpum in China. The suitable habitats of current climate scenarios for T. ruticarpum was 150.76 × 104 km2, mainly distributed in the hilly regions south of the Qinling-Huaihe line and west of the Hengduan Mountains in China. The suitable area for T. ruticarpum showed a continuous expansion trend under different climate scenarios. The centroid generally exhibited a trend of migrating towards higher latitudes. This study provided a scientific reference for the rational introduction and production planting of T. ruticarpum.
