摘　　要：减污降碳协同增效是我国促进经济社会发展全面绿色转型的重大战略举措,而城市重点排放源是碳和大气污染物排放的主要来源,因此探究重点排放源在不同控制策略下的城市减污降碳协同效应及空气质量改善效果具有重要意义。本文以湖南省湘潭市重点排放源为研究对象,并设置了8种不同排放控制策略情景,基于LEAP模型量化评估各控制策略的减污降碳协同效应;在此基础上,通过RSM-VAT系统模拟评估各控制策略情景的空气质量(PM_(2.5))实时响应浓度及其改善效果。对湘潭市的实证研究结果表明:①在各排放控制策略情景中,产业结构调整和能源效率提升单一控制策略情景(S1和S3)及其组合控制策略情景(S5)的减污降碳协同效应较好,而能源结构优化及其组合控制策略情景的协同效应较弱。②各排放控制策略对碳减排总量的影响呈能源结构优化>能源效率提升>产业结构调整的特征,其减排率分别为18.3%、6.1%、4.5%;而对大气污染物减排当量的影响呈能源效率提升>能源结构优化>产业结构调整的特征,其减排率分别为8.3%、6.6%、3.6%。③各项重点排放源控制策略对城市目标年空气质量改善均具一定效应,且组合控制策略情景优于单一控制策略情景。研究显示,城市大气污染重点排放源控制策略的制定实施对减污降碳协同增效和空气质量改善均具有显著的推动作用。Achieving synergistic effects between pollution reduction and carbon emission reduction is a major strategic initiative to advance the comprehensive green transformation of economic and social development in China.Urban key emission sources are primary contributors to carbon and atmospheric pollutant emissions,making it crucial to explore the synergistic effect of pollution and carbon emissions reduction and air quality improvement under different control strategies for these key emission sources in urban areas.This study focuses on the key emission sources of Xiangtan City,Hunan Province and evaluates eight different emission control strategy scenarios.The synergistic effects of pollution and carbon emissions reduction for each control strategy are quantified using the LEAP model.On this basis,the real-time response concentrations of air quality(PM_(2.5))and the improvement effects of various control strategy scenarios are simulated and assessed using the RSM-VAT system.The results show that:(1)Single control strategies(S1 and S3)for industrial restructuring and energy efficiency improvement,as well as their combined control strategy scenario(S5),show better synergistic effects on reducing pollution and carbon emissions,while the synergistic effects of energy structure optimization and its combined control strategies are weaker.(2)The impact of various emission control strategies on total carbon emission reduction is characterized as follows:energy structure optimization>energy efficiency improvement>industrial restructuring,with reduction rates of 18.3%,6.1%and 4.5%,respectively;whereas the impact on the equivalent reduction of atmospheric pollutants is characterized as follows:energy efficiency improvement>energy structure optimization>industrial restructuring,with reduction rates of 8.3%,6.6%and 3.6%,respectively.(3)All key emission source control strategies have a certain effect on improving the air quality of the city in the target year,and the combined control strategy scenario is better than the single co
