Land use change is an important factor that affects the carbon cycle process of terrestrial systems and climate change.In order to seek the optimal carbon emission reduction path for terrestrial space and realize the optimization of low-carbon green national land spatial pattern，this study selected Wuhan as a case study area.Based on linear programming and Markov model，the land use structure of Wuhan in 2035 under different scenarios was formed.The cellular automata model incorporating spatial autocorrelation effect was used to simulate the land use spatial layout based on different land use structures，then the carbon emissions in the future under different land use structures and spatial layouts was analyzed，and finally a low-carbon land use pattern that meets the future development goals of the city was proposed.The results showed that in the natural development scenario and the economic priority scenario，the construction land and cultivated land area will change significantly，and the total carbon emissions will increase by 8.25% and 29.06%，respectively.Under the low-carbon oriented scenario，the growth rate of construction land slowed down，the forest land increased significantly，and the total carbon emissions increased by 5.46%.From the perspective of spatial form，under the natural development scenario and the economic priority scenario，the construction land expands outward around the central urban area obviously，and the scattered construction land in the far urban area was gradually merged.Under the low-carbon oriented scenario，the increase of construction land was limited，the increase of forest land in the far urban area was obvious，and the ecological framework of multi-ecological green wedges and ecological corridors was gradually formed.The above results showed that the simulation results under different scenarios can all show the impact of different development strategies on the territorial spatial pattern of Wuhan.The carbon emissions situation of the economic priority scenario that emphasizes the maximization of economic benefits is not optimistic.The new pattern of national land space development and protection integrated with the low-carbon concept can achieve the goal of green carbon reduction while taking into account the speed of economic growth.
