[Analysis of the Spatiotemporal Evolution of Carbon Reserves in Shaanxi Province Under Different Scenarios in the Future].

To understand the land use development trends in Shaanxi Province under different scenarios and effectively assess the spatiotemporal evolution of terrestrial ecological carbon stocks in Shaanxi Province under land use changes, the study used Markov-FLUS and InVEST models to analyze the impact of land use changes in Shaanxi Province from 2000 to 2020. The impact of carbon storage changes and the spatiotemporal changes in land use structure, carbon storage, and carbon density under three different scenarios were simulated and assessed in Shaanxi Province in 2025 and 2030. The results showed： ① The ROC values of various categories in the coupled Markov-FLUS model were all above 0.
