[Objective] The spatiotemporal evolution characteristics of regional land use and carbon storage were analyzed,in order to predict future changes in land use and carbon storage,thereby provide a scientific basis for achieving the 'dual carbon' goals and sustainable development.[Methods] Taking Pingxiang City as a case study,this study analyzed the spatiotemporal evolution characteristics of land use and carbon storage,explored the impact of land use change on carbon storage,and identified areas requiring protection and restoration through hot and cold spot analysis. Subsequently,the PLUS model was used to predict land use and carbon storage under different scenarios in 2035.[Results] ① From 2010 to 2024,the expansion of cultivated land and artificial surfaces encroached on forests with higher carbon density,leading to a reduction of carbon storage of 2.29×10⁶ t. ② Two areas with relatively high hot spot intensity in the central-southern region were fragmented. Measures should be taken to make them more concentrated to improve carbon sequestration efficiency. ③ Among the predictions under the natural development, cultivated land protection, ecological protection, and urban development scenarios,carbon storage under the ecological protection scenario decreased by only 0.24%,while the other three scenarios showed significant reductions due to newly scattered artificial surfaces within forests in the central-southern region.[Conclusion] In Pingxiang City,the expansion of artificial surfaces and cultivated land leads to a reduction in forests and a decline in carbon storage. Therefore,it is necessary to protect forests in the central-southern region,optimize the layout of artificial surfaces,and minimize carbon loss under the ecological protection scenario.
