Abstract: It is crucial to clarify the relationship between the spatial distribution of “production-living-ecological” space (PLES) and urban resilience for exploring the urban environmental situation caused by rapid urban expansion and intensified carbon emissions. Based on the perspective of PLES, we constructed an evaluation system for PLES and urban resilience by considering the carbon emissions, POI (point of interest) data, and nighttime light data. We further assessed the rationality of spatial patterns and urban risk tolerance according to the spatial coupling coordination degree and urban resilience measurement. The results showed that: (1) Between 2010 and 2022, the highvalue area of production space in the Liaodong Peninsula increased by 1228 km2, ecological space decreased by 222 km2, and living space increased by 449 km2. (2) Between 2010 and 2022, the overall urban resilience showed a trend of first increasing and then decreasing, with a decline of 29.4% in production resilience, 10.29% in living resilience, and 14.16% in ecological resilience. Production resilience had a greater impact on the overall urban resilience, while ecological resilience had lesser effect on the overall urban. (3) The level of coupling coordination in most areas of the Liaodong Peninsula was predominantly highly positively correlated, exhibiting a spatial aggregation state. In terms of urban resilience, the aggregation degree of ecological resilience was higher than that of production resilience and living resilience. Therefore, the distribution of the PLES in the Liaodong Peninsula varied greatly, with ecological space gradually decreasing and production space rapidly expanding. The Liaodong Peninsula should enhance efforts in ecological environmental protection and balance the PLES pattern.
