Abstract: Based on the land use data of Suiling county in 2000,2010 and 2020 changes in carbon stock in Suiling county from 1990 to 2018 were calculated using the InVEST model, and changes in landscape pattern and carbon stock of Suiling county under three scenarios were simulated using the FLUS model and the Fragstats model.Taken together, these all provide suggestions for the green and low-carbon development of Suiling county.The results showed that, 1) Suiling county mainly benefited from the protection of forest resources during the period from 2000 to 2010,with increased landscape fragmentation, decreased spreading degree and increased carbon stock（1.076×10~5 t in total）.While Suiling county showed intensified landscape fragmentation, increased landscape heterogeneity, and decreased carbon stock（0.609×10~5 t in total） during the period from 2010 to 2020.2) Landscape heterogeneity increased in all three scenarios, while ecological protection scenarios changed slightly compared with other two scenarios.Carbon stock in natural development scenarios and farmland protection scenarios showed a downward trend, with a value of 18.051×10~6 t and 18.059×10~6 t, respectively.Ecological protection scenarios showed increased carbon stock of 18.116×10~6 t, which was 6.08×10~4 t higher than that of natural development scenarios.In conclusion, by analyzing the characteristics of land landscape pattern changes in different scenarios in Suiling county, the changes of carbon storage were calculated.Among them, the ecological protection scenario was more conducive to urban development.We should follow the low-carbon urban development model, take the living environment as the guide, rationally organize the division of land resources, and promote the construction of ecological green urban areas.
