Abstract：To investigate the impacts of land use changes on ecosystem services under different scenarios,the urban agglomeration of the middle Yangtze River was taken as a case study.Land use patterns under four scenarios in 2030 were simulated using the patch-generating land use simulation(PLUS)model.Meanwhile,the integrated valuation of ecosystem services and tradeoffs(InVEST)model was employed to evaluate the spatiotemporal changes in four key ecosystem services,namely,current and future carbon storage,habitat quality,water yield,and soil conservation in the region.The results showed that ecosystem services exhibited significant spatial heterogeneity,and the spatial distributions of different ecosystem service functions remained largely unchanged over time.It was revealed by multi-scenario comparisons that only the ecological protection scenario could achieve improvements in carbon storage and habitat quality.In the remaining scenarios,water yield was generally increased,but this was accompanied by decreases in carbon storage and habitat quality,while soil conservation fluctuated slightly across all scenarios.Land use change was identified as the key factor influencing ecosystem services,and different changes in ecosystem services were exhibited under different scenario simulations.The study indicated that scientific land allocation was an important approach to balancing urban development and ecological protection.
