Abstract:
Objective To predict the potential geographical distribution of Lamiophlomis rotata(Benth.)Kudo,a unique Tibetan medicinal plant endemic to the Tibetan Plateau,using a multi-model ensemble strategy;To analyze the key environmental driving factors of its suitable habitat.Methods Based on 163 distribution records of L.rotata collected through field surveys and database resources,and incorporating multi-dimensional environmental factors,including bioclimatic and topographic variables,an efficient ensemble prediction model was developed using the Biomod2 platform.The potential distribution of L.rotata on the Tibetan Plateau was simulated and predicted.Habitat suitability maps were generated using ArcGIS 10.3,and the main environmental factors influencing the distribution of L.rotata were analyzed.Results The ensemble model demonstrated outstanding predictive performance,with TSS and AUC values of 0.916 and 0.992,respectively,significantly outperforming all individual models included in the ensemble.Further analysis revealed that elevation,annual precipitation and temperature seasonality were the primary environmental factors influencing the distribution of L.rotata.The primary areas of high habitat suitability for L.rotata on the Tibetan Plateau are located at the borders of Qinghai,Tibet,Sichuan and Gansu provinces,covering an area of approximately 72.92×104 km2.Conclusion L.rotata exhibits unique adaptations to high-altitude and specific climatic conditions.The results of this study can provide valuable insights for the ecological conservation and rational utilization of its medicinal resources.The multi-model ensemble approach demonstrates significant advantages in improving the accuracy of species distribution predictions.
