| 英文摘要 | Urban heat exposure and energy-related CO2 emissions represent two critical but often spatially overlooked dimensions of urban climate. This study provides a subdistrict-level analytical framework to examine how daytime Land Surface Temperature(LST), nighttime LST, and diurnal temperature variation relate to localized CO2 emissions across 139 subdistrict units in the downtown of Beijing. Multi-temporal moderate resolution LST, 1 km open-data inventory for anthropogenic carbon dioxide emissions, and ecological, morphological, and socioeconomic indicators are integrated to reflect intra-urban spatial patterns. Bivariate Moran's I and Hotspot statistics reveal thermal and emission spatial aggregation, while Geographical-eXtreme Gradient Boosting(XGBoost) integrated with SHAP identifies nonlinear and varying drivers of thermal conditions. Results reveal intra-urban heterogeneity, daytime LST is primarily affected by green rate and building density, nighttime by building density and road network density, and diurnal ranges by housing price and green rate. In contrast, CO2 emissions remain concentrated in peripheral industrial and logistics belts rather than in inner subdistricts, demonstrating a heat-carbon spatial decoupling that challenges the conventional assumption of heat-carbon co-location. These findings clarify the distinct spatial logic governing thermal and emission hotspots and highlight the need for differentiated interventions, heat-mitigation strategies should target built inner districts, whereas decarbonization efforts should focus on functional zones. The proposed framework provides an approach for understanding heat-carbon interactions in rapidly urbanizing megacities. |
