基于最大熵模型和地理探测器的大花红景天潜在适生区预测及影响因素分析
Analysis on Potential Suitable Areas and Influencing Factors of Rhodiola crenulata Based on MaxEnt Model and GeoDetector
摘要
Abstract
Objective To explore the spatial distribution patterns of potential suitable areas of Rhodiola crenulata under current and future different climatic conditions and the influencing factors of suitable habitats.Methods Based on the MaxEnt model and ArcGIS 10.8.1 software,82 selected distribution spots data of Rhodiola crenulata and 6 environmental factors data were used,combined with overlay analysis of land use data,to predict the distribution patterns of suitable areas and the centroid migration trajectory of Rhodiola crenulata under current and future climate change scenarios.Results Altitude,solar radiation in July,isothermality,and temperature seasonality were the main environmental factors affecting the suitable habitat area of Rhodiola crenulata.Under current climatic conditions,the total potential suitable habitat area for Rhodiola crenulata was 1.27×106 km2,among which the suitable habitat of grasslands,forests,and croplands accounted for 65.43%,22.83%,and 3.04%of the total suitable habitat area,respectively.Under the future climate scenarios of SSP126 and SSP585,the suitable habitat areas for Rhodiola crenulata will show an expansion trend compared with the current situation,and the centroid will generally migrate slightly toward the southwest.Conclusion The results of this study can provide a reference for the conservation and sustainable utilization of Chinese materia medica resources of Rhodiola crenulata.关键词
