Analyzing the complex dynamics of land use, accurately assessing ecosystem service values (ESVs), and predicting future trends in use ESVs alterations within spatial constraints policies are essential for policymaking advancing sustainable development objectives. This study analyzed use/land cover (LULC) changes Yunnan Province from 2005 to 2020. Policy were incorporated into scenario simulations, an improved equivalent factor method, Markov-PLUS model, global autocorrelation, Getis-Ord Gi* method applied predict analyze LULC under different scenarios 2030. The findings revealed following: (1) Forests grasslands dominant categories YNP, with notable patterns recorded between (2) total area increased by CNY 8.152 billion during this period, exhibiting initial decline followed gradual recovery. (3) Simulations 2030 indicated that natural would lead most extensive urbanization, while ecological conservation yield greatest increase ESVs. In contrast, only farmland led food production-related ESVs, but resulted lowest among three scenarios. These results contribute understanding impacts on provide insights formulating scientifically sound effective protection policies.

The construction of ecological networks and the optimization spatial layouts are essential for maintaining regional security promoting sustainable development, especially in high-population-density urban agglomerations. This study employs Central Plains Urban Agglomeration (CPUA) as a case to establish an network through quantitative assessments land use/cover change (LUCC) ecosystem service value (ESV), utilizing morphological pattern analysis (MSPA) methods tools such Linkage Mapper further optimize layouts. findings reveal following: (1) use structure within CPUA experienced notable shifts. magnitude changes ranked follows: > cultivated grassland waterbody forest bare land. (2) southwestern mountainous hilly regions, designated high ESV areas, primarily rely on water conservation soil retention functions. In contrast, central western characterized by low ESVs, dominated land, significantly influenced urbanization agricultural activities. (3) An system was developed based region’s natural geographic features, incorporating 20 sources covering approximately 21,434.70 km2, 36 corridors with combined length around 2795.19 km. extends north–south direction parts CPUA. (4) Considering optimized layout “five belts, six zones, multiple clusters, corridors” proposed, along differentiated restoration strategies tailored address specific issues different regions. aims harmonize protection economic providing scientific foundation valuable reference planning policies.
