Land use optimization research based on FLUS model and ecosystem services–setting Jinan City as an example

Abstract

Environment and development are essential components in the process of human development, and the limitation of land necessitates rational use. To cope with the impact of urban expansion on the environment, in this study, the idea of anti-planning is examined. The ecosystem service function is considered a limiting factor, and it determines 28.94% of the land in the study area as the core eco-land area, setting it as the non-construction area. At the same time, future land use status of the study area in 2025 is determined by planning restrictions and multiyear land use predictions, and finally, optimal allocation of land in the study area is determined by using the FLUS(Future Land Use Simulation) model. The simulation results show that the ecological security pattern and landscape index of the city are optimised, fragmentation of the landscape has decreased, and aggregation degree has increased.
