Amid global climate change, the pursuit of low-carbon development has become a unified international goal. The Qinba Mountain region plays an important role in maintaining China's ecological security, making spatial zoning tailored for carbon neutrality vital local sustainable development. Using land use and socioeconomic data from 2000 to 2020 81 county-level units, neutral framework was developed, considering natural, economic, resource factors. This study further integrated spatiotemporal dynamics index multi-scenario predictions future emission (CE) zoning. results revealed that had overall positive net-carbon trend without significant deficits, central faced increased CE northern weak carrying capacity. predicted continued decrease under scenario reached 30.55 million t by 2060, with only nine units failing reach their peaking 2030. Five different zones were identified: sink functional zone, stabilization high-carbon control zone source optimization zone. Tailored strategies each proposed enhance regional environment contribute green These findings offer insights into achieving regions or cities.

The pressing need to address climate change and advance global sustainable development has heightened the emphasis on ecosystem services, especially carbon sequestration. This research assesses supply demand dynamics of sequestration services Hainan Island, China, highlighting its significant contributions biodiversity conservation balance. analysis considers spatial distribution interrelation these in light recent land use ecological policy changes. methodology incorporates cover data, Normalized Difference Vegetation Index (NDVI), meteorological soil data. A gravity model is employed elucidate supply–demand relationship for examining flow across different regions identifying connections their intensities. results indicate a notable increase from 2000 2020, particularly central mountainous areas. Conversely, risen, northern plains’ urban areas southern coastal towns. reveals strong interdependence between zones high-demand locales. study underscores disparities Hainan, emphasizing strategic management elements. It provides critical data compensation policies offers insights into roles regional ecosystems mitigation. highlights necessity incorporating land-use planning decision-making foster strengthen resilience.

Equilibrating the supply and demand for ecosystem services (ESs) is essential sustainable development. Nonetheless, elements like policy modifications, land utilization, climate change are profoundly transforming dynamics of service (ESSD). As a result, there an imperative necessity to methodically evaluate predict these alterations by including both social environmental elements. This study utilized Henan region Yellow River Basin (HYRB) as case forecast in three ESs—water production (WY), carbon storage (CS), food (FP)—under scenarios 2030 2050, grounded SSP-RCP framework. We further evaluated supply–demand equilibrium at grid county degrees. The results indicate following key findings: (1) From 2020 significant spatial differences services. While CS FP exceeds demand, WY falls short. (2) ratios projected decline under all scenarios, whereas expected continue growing. Surplus areas aggregated northwest, southwest, central areas, while surpluses found eastern northern plains. Deficits primarily located urban areas. (3) dominant patterns matching also vary. exhibit high–low agglomeration patterns, particularly northwest southwest mountain regions, shows low–low agglomeration, mainly These findings enhance comprehension ESSD, serving foundation preservation advancement Basin, China.
