氟氯烃（HCFCs）是氟氯烃的主要替代品，受《蒙特利尔议定书》管制。自本世纪初以来，中国的HCFC排放量迅速增加。然而，基于大气测量的限值报告可用于2011年以后的年份，这是预计会发生重大变化的重要时期。利用基于柔性粒子弥散模型的贝叶斯反演技术，结合中国7个站点的大气观测资料，估算了2011-2017年中国4种主要HCFCs的排放量及其变化。所有四种HCFCs的排放量在2015年之前达到峰值。我们的结果与报告的自下而上的库存非常吻合。2011年至2016年，中国臭氧消耗潜力（ODP）加权的三种最丰富的HCFCs排放量占全球总量的37%。中国、欧盟和美国的HCFC - 22总排放量约占全球总量的一半，这表明世界其他地区的HCFC排放量很大。
Hydrochlorofluorocarbons (HCFCs), the main substitutes of chlorofluorocarbons, are regulated by the Montreal Protocol. Chinese HCFC emissions increased fast from the beginning of this century. However, limit reports based on atmospheric measurement are available for years after 2011, an important period when significant changes are expected. Combining atmospheric observations at seven sites across China with a FLEXible PARTicle dispersion model‐based Bayesian inversion technique, we estimate emission magnitudes and changes of four major HCFCs in China during 2011–2017. The emissions of all four HCFCs reached peaks before 2015. Our results agreed well with the reported bottom‐up inventories. The Chinese ozone depletion potential (ODP)‐weighted emission of the three most abundant HCFCs accounted for 37% of global totals from 2011 to 2016. The total emission of HCFC‐22 from China, the European Union, and the United States accounted approximately a half of the global totals, suggesting large HCFC emission emitted from the rest of the world.
