5 Conclusion
In the study, the potential suitable Satyrium habitat in China was predicted based on the MaxEnt model optimized by the ENMeval package. Temperature was the common variable in the three species. In regard to S. nepalense , precipitation is one of environment variables influencing its geographic distribution. The potential geographical distribution of Satyrium under current climatic conditions is primarily on the southwest side of China.Satyrium ’s highly suitable habitat area, moderately suitable habitat area, and total suitable habitat area were predicted to increase under future climate change scenarios. The highly suitable habitat area of Satyrium showed a tendency to shift to areas with higher elevation. In regard to future changes in suitable habitat areas, both the gained and lost areas ofSatyrium will increase in emission concentrations; however, the gained area will be larger than the lost area. These results can provide theoretical guidance for protecting endangered plants in China and offer further reference for biodiversity protection in China.
