[Objective]Land use change affects ecosystem services value(ESV). The aims of this study are to examine land use change, to assess ESV under multiple scenarios, and to optimize land management and maintain ecological security. [Methods]Firstly, four scenarios were set up to find the optimal solution of land use structure under different objectives through multi-objective programming(MOP). And then, the spatial distribution of land use in 2030 was predicted with the help of PLUS model. Moreover, ESV was evaluated by the equivalent factor method. Lastly, spatial autocorrelation was used to analyze the clustering characteristics, while Pearson correlation coefficient was used to explore the synergistic relationship of trade-offs. [Results](1)From 2000 to 2020, land use types in Yinchuan City were dominated by cropland and grassland, with construction land expanding by 473.1 km2, cropland and grassland decreasing.(2)The natural evolution scenario and economic priority scenario increase in construction land and decrease in grassland. The ecological priority scenario increases in forest and grassland, and decreases in cropland by 363.9 km2. The sustainable development scenario has almost the same cropland and increases in forest and water area.(3)ESV shows a decreasing trend, and the overall ESV of the four scenarios is 4.718 4 billion yuan, 4.540 4 billion yuan, 5.392 4 billion yuan, and 4.971 1 billion yuan, respectively, with hydrological regulation and climate regulation dominating.(4)There are extensive and significant synergistic relationships among the 11 ESV, with low synergies between food production and others. [Conclusion]Sustainable development scenario reversing the downward trend of ESV and achieving high economic benefits can provide a basis for planning. Strengthening the protection of forest and water area is conducive to the improvement of ESV.
