Faced with the background of natural resources integration and the more complex land use structure, it is difficult to effectively meet the demand for rational land use planning with a single land use structure optimization method. Considering the objectives of sustainable utilization of land use, ecological civilization, rural development, and urban-rural integration, we constructed an integrated system for land use structure and layout optimization, which will play a positive role in improving the applicability of planning. This study first sets three scenarios of natural evolution, economic priority, and ecological priority, and then uses the MOP model (multi-objective planning model) to calculate the optimal land use structure under different scenarios. Finally, it can carry on land use layout optimization based on the GeoSOS-FLUS model in 2030, Jintan district, Jiangsu province, China. Results show that, by integrating the MOP and GeoSOS-FLUS models and adopting the "Structure + Constraint + Layout + Criterion" approach to optimize the land use structure and layout in the county, it is conducive to optimize the quantitative land use structure and improve the land use spatial distribution; from the results of the case analysis, the area of industrial and mining land in cities and towns has increased by 39% and 95% under the natural evolution and economic efficiency priority scenarios; the forest land has increased by 40% under the eco-efficiency priority scenario; rural settlements decreased by 33%, 66% and 66%, respectively in the three scenarios. Under the three development scenarios, the spatial pattern will face the two-level differentiation of urban space and ecological space. In the later period of regional development, it is necessary to strengthen the coordinated development of urban and rural land use and ecological protection, and promote a balanced spatial distribution.
