Over the past two decades, tea plantation area in Meitan County, China, has expanded nearly 30-fold, driving significant land use and cover changes (LUCC) with unclear impacts on regional carbon storage. This study uses PLUS-InVEST model to analyze LUCC storage from 2000 2020 predict future by 2060. Results show a decline total 3977.83 × 104 t 3960.85 2020, primarily due reductions cultivated grassland. Although forest plantations increased, overall trend remained negative. Multi-scenario simulations indicate that sustainable development scenario (SDS) mitigates loss, decrease of 31.53 t, compared larger natural (NDS) economic (EDS) scenarios. Under SDS scenario, grassland increased while construction expansion was controlled. emphasizes optimizing agricultural management enhance sequestration protect ecosystems, highlighting need for balance between ecological protection County.
