Abstract It is of great practical significance to explore the relationship between urbanization and CO 2 emissions for low-carbon development cities. However, multiscale assessment spatial population, land economic lacked. In this study, we first adopted statistical methods evaluate pattern China’s in 2019. Then, spatially quantified land, population economy based on data. Finally, used geo-weighted regression model at national-economic zone-province scale. The results displayed that there obvious heterogeneity emissions. significant positive correlation were mainly located northeastern, eastern southwestern regions, consistent with characteristics Heihe–Tengchong Line. uneven would lead more We suggest China should attend balanced urban economy, avoid additional carbon caused by incongruence, further

The concept of major function-oriented zones is highly compatible with the idea spatially synergistic carbon reduction. In this study, 2005–2020 taken as research period, and 305 counties in Yangtze River Delta (YRD) region are unit. S0M-K-means clustering model GeoDetector adopted on basis emission/absorption accounting to analyse spatial temporal variations balance YRD region. Furthermore, zoning influencing factors analysed. Then, a regional reduction pathway proposed. results show that absorption struggles offset emissions; imbalance gradually becoming worse; each county’s shows significant imbalance. Optimised development key high-value agglomerations emissions, while main sources sinks ecological functional zones. has 87 high control zones, 167 emission optimisation 51 sink which further subdivided into 9 types accordance (MFOZs).

In recent years, the “dual carbon” issue has become a major focus of international community. Changes in land use driven by anthropogenic activities have profound impact on ecosystem structure and carbon cycling. This study quantitatively assesses spatiotemporal changes cropland occupation supplementation Pearl River Delta from 2000 to 2020 using InVEST model, analyzing spatial clustering storage caused variations area. The PLUS model was employed simulate land-use patterns distribution four future development scenarios. results indicate following: (1) From 2020, net change rate area −0.81%, with decrease 16.49 km2 area, primarily converted built-up forest land.

Ecological carbon sinks, pivotal in mitigating emissions, are indispensable for climate change mitigation. Counties, as the fundamental units of ecological space management, directly impact achievement regional dual targets through their levels sink. However, existing research has overlooked intricate relationship between terrain features and spaces, leading to a lack specific guidance on enhancing sink counties with diverse landform characteristics. This study focused Jingbian County (Loess Plateau), Fuping (Guanzhong Plain), Chenggu (Qinba Mountains), each characterized by distinct proposes comprehensive identification model within context targets. Utilizing this basis, land use structure, potential, spatial patterns different were systematically analyzed. The results indicated substantial disparities capabilities, distributions among types. Specifically, was predominantly covered grassland, exhibiting moderate overall capacity, baseline spaces playing significant role. Conversely, County, dominated cultivated construction land, exhibited lowest non-ecological accounting staggering 85.93%. other hand, dominance forestland, nearly all its originating from core occupying position.
