Prediction of Suitable Habitats and Analysis on Influencing Factors for the Source Species of Daphnes Cortex Based on MaxEnt Model
摘要
Abstract
Objective To analyze the potential suitable distribution areas of Daphne giraldii,Daphne retusa,and Daphne tangutica—the source species of the TCM and Tibetan medicine Daphnes Cortex;To provide a basis for their resource conservation.Methods This study employed the MaxEnt model to predict the potential suitable habitats of these three Daphnes Cortex source species based on screened distribution records and environmental factors.Geographical detector analysis was applied to analyze spatial heterogeneity in habitat suitability.By incorporating land cover types(cropland,forest,shrubland),the actual usable areas within potential suitable zones were refined.Additionally,conservation areas for Daphnes Cortex were identified by overlaying national nature reserve data.Results Running results based on MaxEnt model indicated that solar radiation,water vapor pressure,precipitation,and temperature seasonal variation coefficient were the dominant environmental factors influencing Daphnes Cortex distribution.The predicted suitable areas for Daphne giraldii,Daphne retusa,and Daphne tangutica were 1.07×106 km2,1.09×106 km2,and 1.32×106 km2,respectively.Overlay analysis with land cover data indicated actual feasible habitats of 7.69×105 km2,7.10×105 km2,and 8.15×105 km2 for the three source species.Conservation hotspots covered approximately 6.12×105 km2,yet less than 20%overlapped with existing nature reserves.Conclusion This study provides references for the conservation of wild resources and artificial cultivation of Daphnes Cortex source species,aiming to achieve sustainable development of medicinal resources of Daphnes Cortex.关键词
