[Objective] The Silk Road Economic Belt facilitated rapid economic development in cities along its route, resulting in significant changes in land use. Investigating the carbon stock variations caused by land use in this region was crucial for optimizing land use patterns and achieving the carbon peaking and carbon neutrality goals. [Methods] The PLUS-InVEST model was employed to assess and predict the carbon stock situation in five provinces and cities along China’s Maritime Silk Road between 1980 and 2030. The model simulated the spatiotemporal characteristics of carbon stock changes under multiple scenarios of land use, aiming to explore the impact of land use on carbon storage. [Results] The research findings indicate that over a span of 50 years, there has been a significant reduction in arable land and a substantial increase in construction land in the region. Forest land has managed to maintain a basic dynamic equilibrium during this period. However, there has been a considerable loss of carbon storage
