Abstract Resource-based cities (RBCs) have historically been constrained by their inherent characteristics, impeding rapid shifts in energy consumption patterns and exerting substantial pressure on regional decarbonization efforts. Herein, 18 RBCs southwestern China were taken as the research object. Firstly, a resilience index system was constructed for resource ecosystem socio-economic of RBCs, optimization mutation level algorithm used to measure each city. Secondly, an interval prediction model established carbon emissions based GA-DBN-KDE algorithm. Finally, setting 16 scenarios, emission range “carbon peak” time Southwest from 2023 2040 predicted, scientific path low-carbon development explored under differentiated scenarios. The results indicated that: (1) urban levels both rise; (2) demonstrated excellent performance; (3) simulation scenarios revealed varying specific paths achieve peak, underscoring necessity city-specific policy formulation. Overall, this paper provides new analytical method transformation further forging basis decision-makers formulate reduction measures.

Urbanization and its impact on land use cover change are key drivers of global carbon balance shifts. Understanding the spatiotemporal evolution in relation to urbanization helps optimize regional planning sustainable development. This study develops a city-level system quantify dynamics across 130 cities Yangtze River Economic Belt (YREB). Moran’s Index is applied assess spatial correlation balance, Environmental Kuznets Curve (EKC) used explore relationship between levels net emissions. The results show following: (1) From 2005 2021, absorption YREB remained relatively stable, whereas emissions increased. Net increased by 574.61, 456.16, 1163.60 Mt C upper, middle, lower reaches, respectively. Nearly 98% exhibited index greater than 1, indicating deficit. Carbon emission intensity displayed decreasing trend, with most significant reductions observed middle reaches. (2) Land exhibits positive correlation, northeastern reaches southwestern upper forming “high–high” “low–low” clusters. (3) per capita followed an inverted “N”-shaped curve, turning points at around 30% 85% urbanization. provides insights into optimizing management amidst urban growth YREB.
