Sustainability, 2020, vol. 12, issue 20, 1-17 Abstract: The rapid development of industrialization and urbanization has resulted in a large amount of carbon dioxide (CO 2 ) emissions, which are closely related to the long-term stability of urban surface temperature and the sustainable development of cities in the future. However, there is still a lack of research on the temporal and spatial changes of CO 2 emissions in long-term series and their relationship with land surface temperature. In this study, Defense Meteorological Satellite Program’s Operational Linescan System (DMSP/OLS) data, Suomi National Polar-orbiting Partnership (NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) composite data, energy consumption statistics data and nighttime land surface temperature are selected to realize the spatial informatization of long-term series CO 2 emissions in the Yangtze River Delta region, which reveals the spatial and temporal dynamic characteristics of CO 2 emissions, spatial autocorrelation distribution patterns and their impacts on nighttime land surface temperature. According to the results, CO 2 emissions in the Yangtze River Delta region show an obvious upward trend from 2000 to 2017, with an average annual growth rate of 6.26%, but the growth rate is gradually slowing down. In terms of spatial distribution, the CO 2 emissions in that region have significant regional differences. Shanghai, Suzhou and their neighboring cities are the main distribution areas with high CO 2 emissions and obvious patch distribution patterns. From the perspective of spatial trend, the areas whose CO 2 emissions are of significant growth, relatively significant growth and extremely significant growth account for 8.78%, 4.84% and 0.58%, respectively, with a spatial pattern of increase in the east and no big change in the west. From the perspective of spatial autocorrelation, the global spatial autocorrelation index of CO 2 emissions in the Yangtze River Delta region in the past 18 years has been greater than 0.66 ( p < 0.01), which displays significant positive spatial autocorrelation characteristics, and the spatial agglomeration degree of CO 2 emissions continues to increase from 2000 to 2010. From 2000 to 2017, the nighttime land surface temperature in that region showed a warming trend, and the areas where CO 2 emissions are positively correlated with nighttime land surface temperature account for 88.98%. The increased CO 2 emissions lead to, to a large extent, the rise of nighttime land surface temperature. The research results have important theoretical and practical significance for the Yangtze River Delta region to formulate a regional emission reduction strategy.
