[Objective] The evolution of land use and its impact on carbon storage were investigated, in order to provide a scientific basis for maintaining regional carbon balance and improving regional carbon storage. [Methods] The PLUS-InVEST model was employed to analyze the spatiotemporal characteristics of carbon storage in Leshan City from 2000 to 2020. The carbon storage under the natural development scenario and the ecological protection scenario in 2030 was predicted. Finally, the center-of-gravity shift model was used to explore the spatial variation of the center of gravity of carbon storage. [Results] ① From 2000 to 2020, carbon storage in the city showed an increasing trend, with a total increase of 2.33×10⁶ t. The contributions of different land use types to carbon storage were ranked as follows: forest land > construction land > water bodies > grassland > unused land > cultivated land. ② In 2030, carbon storage under both scenarios was projected to show an increasing trend. Specifically, it was expected to increase by 2.43×10⁶ t under the natural development scenario and by 2.58×10⁶ t under the ecological protection scenario. ③ Over the past 20 years, the center of gravity of carbon storage in the city shifted westward by 3 121.86 m, with the movement occurring within the Shawan District. Under the natural development and ecological protection scenarios, the center of gravity of carbon storage moved within the Shawan District, shifting 1 236.62 m to the southeastward and 4 226.55 m to the northeastward, respectively. [Conclusion] Land use change and carbon storage change are consistent, and land types with strong carbon sequestration capacity have a significant impact on carbon storage. Regional ecological environmental protection can be achieved by controlling the transfer of these land types.
