Prediction of Potential Distribution Area of Eupatorium adenophorum in China Under Climate Change

In this paper, the maximum entropy MaxEnt model and ArcGIS software were used to predict the potential distribution area based on the distribution data of Eupatorium adenophorum from 2020 to 2023. The results showed that the potential distribution area of E. adenophorum in China was mainly located in central and southwest China, with an area of about 172.55×10⁴ km². The dominant environmental factors affecting its survival and distribution are the lowest temperature of the coldest month, the precipitation and temperature seasonality of the coldest season. In the future 2041−2060s and 2061−2080s, the shared social economic path （SSP） SSP245 and SSP585 scenarios, the potential distribution area of E. adenophorum will spread to the south, and the overall trend of the distribution area will increase. In order to prevent the spread of E. adenophorum in China, scientific prevention and control must be carried out in the invaded areas. For the potential distribution areas and safe areas without invasion, it is necessary to quarantine the species and strengthen the prevention and control of the E. adenophorum population.
