Abstract:
Objective To analyze the habitat suitability status of Rhododendron anthopogonoides Maxim.in Gansu and Qinghai Provinces;To predict its potential suitable areas in different climate scenarios;To provide references for the protection and rational utilization of Rhododendron anthopogonoides Maxim.Methods The MaxEnt model,combined with ArcGIS 10.3,was used to simulate and analyze the potential habitat suitability and spatial distribution of Rhododendron anthopogonoides Maxim.under current and future climate conditions,using species distribution data and environmental factors.Additionally,the habitat suitability was classified,and key environmental factors influencing the distribution of Rhododendron anthopogonoides Maxim.under current climate conditions were identified through a comprehensive evaluation of factor contribution rates and validation using the Jackknife method.Results The predicting results showed that under the current climate,the total area of potential suitable habitat for Rhododendron anthopogonoides Maxim.was 21.27×104 km2,primarily distributed in Lanzhou,Linxia Hui Autonomous Prefecture and Gannan Tibetan Autonomous Prefecture in Gansu Province,and in Xining,Haidong,Huangnan Tibetan Autonomous Prefecture and Hainan Tibetan Autonomous Prefecture in Qinghai Province.Under different future climate scenarios,the potential suitable habitat area was projected to increase by 4.51%to 21.91%,and migrating to high altitude areas.Elevation,precipitation in the driest month,annual precipitation and the average temperature in the driest quarter were identified as the main environmental factors influencing the distribution of Rhododendron anthopogonoides Maxim.Conclusion Under different climate scenarios in the future,the habitat area of Rhododendron anthopogonoides Maxim.in Gansu and Qinghai Provinces is showing an increasing trend,which can provide reference for the protection and rational utilization of Rhododendron anthopogonoides Maxim.resources under climate change.
