Urbanization and economic growth have substantially modified the land utilization structure, affecting ecosystem services their spatial distribution. As a crucial component of Beijing’s urban framework, city’s green belts, located at periphery its core metropolitan area, play vital role in supplying services. They also represent focal point for use transformation conflicts, making them an important study area. This research utilizes data from 2000, 2005, 2010, 2015, 2020 as primary dataset. It adopts standard equivalent factor integrates it with Patch-Generaling Land Use Simulation (PLUS) model to belts 2035 under three scenarios: natural development scenario (NDS), ecological protection (EPS) cultivated (CPS). The aims analyze project temporal evolution service values (ESVs) different scenarios Beijing. results indicate that (1) is dominated by cropland construction land. Construction has expanded significantly since increasing 500.78 km2, while decreased 488.47 km2. Woodland, grassland, water seen reduction. Overall, there trend woodland being converted into cropland, subsequently transitioning (2) In NDS, increases 91.76 decrease. EDS, decelerates 22.09 reduction decelerates, conversion limited. Grassland remain largely unchanged, experiences slight increase. CPS, notably reduced, 11.97 slightly, grassland decreasing slightly.

The Blue Economic Zone of the Shandong Peninsula is located in transitional zone between land and sea, with a complex ecological environment. determination hot cold spots various ecosystem services crucial for coordinated development optimization spatial pattern This study, based on natural socio-economic data, utilizes models to simulate water yield (provisioning service), carbon sequestration (regulating biodiversity (supporting aesthetic scientific research values (cultural service). Using multi-criteria decision-making approach, it identifies different development–conservation scenarios. Combining protection efficiency areas, proposes promotion scheme. indicates significant differences without clear trade-offs synergies. Changes weights 11 scenarios result spots. Compared neutral scenario (S6), distribution (S1–S5) relatively scattered, while (S7–S11), show an increasing trend concentration southeast, scattered west northwest. Four schemes are proposed policy preferences. Promotion areas should focus restoration improvement raise local service levels. Protection emphasize maintaining their existing high-level achieve synergistic enhancement services.
