Abstract: Land use change is a direct factor affecting carbon storage, and the change of carbon storage will directly affect urban climate, social economy and ecosystem service function. Therefore, reasonable land use planning and management has important strategic significance for maintaining and increasing carbon storage. Taking Yantai as an example, three periods of land use data were selected, and GIS and other software were used to analyze the characteristics of land use change. The PLUS-InVEST coupling model was used to analyze the land use change and carbon storage distribution in Yantai in 2035 under the scenario of natural evolution protection. The results showed that from 2000 to 2020, the cultivated land, grassland and other land use types in Yantai continued to decrease, the forest land, water area and construction land continued to increase, and the carbon storage continued to decrease, with an overall decrease of 18.01×10⁶ t. Cultivated land was the main land type with reduced carbon storage. Under different scenarios, the forest land and grassland increased under the ecological protection scenario, the cultivated land, construction land and other land reduced, and the utilization degree of other land reduced. In the ecological protection scenario and the natural evolution scenario, the carbon storage decreased by 10.06×10⁶ t and 11.37×10⁶ t, respectively, and there was little difference in the development of carbon storage in the two scenarios.
