Calculating the fossil energy consumption, revealing the temporal and spatial evolution characteristics of net CO emissions, and analyzing the decoupling effect between social development and net CO emissions in different regions of the Yangtze River Economic Belt (YREB) is crucial to support the different regions, allowing them to select their individual industrial development and carbon emission reduction path. The results showed that:① from 1999 to 2012, YREB became greener, the CO emission of the YREB increased by 2244.23 million tons, and the carbon sink increased by 148.07 million tons during the research period. ② From 2013 to 2018, the area of medium-high carbon sequestration (NPP>800 g·m, count for C) increased by 23.25%, compared with that from 1999-2012. ③ A highly decoupling effect between social development and net CO emissions was found in the downstream of the YREB. The highest decoupling cities in the upstream, midstream, and downstream accounted for 12%, 34%, and 54% of the highest decoupling cities in the YREB, respectively.
计算化石能源消耗，揭示长江经济带（YREB）不同区域净碳排放的时空演变特征，并分析社会发展与净碳排放之间的脱钩效应，对于支持不同区域选择各自的产业发展和碳排放减少路径至关重要。结果表明：①1999年至2012年，长江经济带变得更绿，研究期间长江经济带的碳排放增加了2.24423亿吨，碳汇增加了1.4807亿吨。②与1999 - 2012年相比，2013年至2018年中高碳固存（NPP>800 g·m，计为C）面积增加了23.25%。③长江经济带下游发现社会发展与净碳排放之间存在高度脱钩效应。上游、中游和下游最高脱钩城市分别占长江经济带最高脱钩城市的12%、34%和54%。
