英文摘要Understanding long-term carbon stock dynamics in coastal wetlands is essential for assessing their sequestration potential and informing climate mitigation strategies. However, the combined influences of land use and land cover change (LUCC) and tidal barriers on carbon stock dynamics in coastal wetlands remain unclear. We used Integrated Valuation of Ecosystem Services and Trade-offs (InVEST) model corrected by in-situ measurements to investigate carbon stock dynamics in response to LUCC and tidal barrier construction in the Yellow River Delta (YRD) for the period of 1980-2020. The results indicated that the corrected carbon stock increased by more than twofold. Soil inorganic carbon (SIC) stock significantly exceeded soil organic carbon (SOC) and even total ecosystem organic carbon (EOC, comprising SOC, aboveground, belowground and dead organic carbon) stock. Carbon stocks showed divergent trends over four decades, with inorganic carbon increasing steadily and organic carbon fluctuating in response to land use changes. Specifically, from 1980 to 2020, SIC continuously increased from 3.211 x 107 t/a to 3.335 x 107 t/a (+3.9 %). In contrast, EOC first increased by 0.222 x 107 t (+16.2 %) from 1.376 x 107 t/a to 1.598 x 107 t/a during 1980-1990, but then decreased by 0.141 x 107 t (-8.8 %) to 1.457 x 107 t/a during 1990-2020. The increase in SIC stock was principally owing to the seaward expansion of the YRD, whereas the decrease in EOC stock from 1990 to 2020 was largely attributed to the reduced grassland areas. The severe degradation of wetlands further reduced the carbon stock in the YRD. Large-scale tidal barriers mitigated SIC loss from coastal erosion but did not enhance organic carbon sequestration due to disrupted hydrological connectivity and vegetation shifts. Notably, SIC stock decreased while EOC stock increased with greater distance from tidal barriers. To enhance carbon sinks in large river deltas, future efforts should prioritize ecological restoration through strategic land use conversion.
