Analysis of the suitable habitat of Solidago canadensis L.based on different geospatial and tempo-ral distribution data
To more accurately predict the suitable habitat of Solidago canadensis L.in China,this study employed the MaxEnt model,integrating seven categories of global geographical distribution data from 1903 to 2023 and current geographical distribution data within China,to forecast its potential suitable habitat.The analysis revealed that with the increase in years,the AUC value based on global distribu-tion data decreased from 0.980 to 0.710,with seasonal variation in precipitation(bio15)and mean annual temperature(bio1)being the two primary environmental variables influencing the model's predictions.The predicted suitable habitat range showed an expanding trend,which corresponded with the actual changes in species distribution.However,the AUC value based on Chinese distribution data,although high at 0.977,indicated a suitable habitat range that significantly differed from the global data predictions and did not match the species'actual global distribution.Consequently,the final suitable habitat prediction was conducted using all distribution data worldwide up to 2023.It is recommended to take high-risk pre-vention and control measures in Guizhou,Hubei,Hunan,Anhui,Jiangsu,Zhejiang,Henan,Chongqing,Shang-hai,and Taiwan to effectively cope with the invasion threat of S.canadensis.
