| description | Ecological infrastructure plays a crucial role in strengthening the relationship between humans and the environment by optimizing ecological space and resource allocation in urban environments. However, there are few studies on the functional assessment and spatial and temporal evolution of ecological infrastructure and its layout optimization. In this study, we developed an ecological infrastructure optimization method based on ecosystem service supply, demand, and flow in Yantai City as the study area; identified the spatial extent of urban ecological infrastructure and its spatial and temporal changes based on the spatial quantification of multiple ecosystem services; assessed whether the existing ecological infrastructure could satisfy the needs of the urban residents by calculating the ecosystem service supply and demand indexes; and used the spatial quantification of ecosystem service flows to optimize the spatial layout of urban ecological infrastructure. This study shows that, from 2010 to 2018, ecological infrastructure in Longkou, Zhaoyuan, and Laiyang decreased, contrasting with the growth in the existing peripheral areas. The study found a clear spatial mismatch between the supply and demand of ecosystem services, especially in the central urban areas, suggesting that the existing infrastructure was unable to satisfy the needs of high-demand areas. This study assessed the peripheral areas of the city using comparative ecological radiation force (CERF), including 314.64 km<sup>2</sup> of environmentally beautiful village units as key components of ecological infrastructure in Yantai City. These findings are crucial for sustainable environmental management and urban development strategies. |
