摘要

基于陕西省2022年环境统计数据及部门调研数据,通过自下而上和自上而下相结合的方法建立陕西省2022年大气污染物和CO₂排放清单.结果发现,SO₂、NO_x、CO、VOCs、NH₃、PM₁₀、PM_2.5、BC、OC和CO₂排放总量分别为:64.0x10³, 31.2x10⁴, 19.3x10⁵, 21.5x10⁴, 34.0x10⁴, 67.9x10⁴, 20.8x10⁴, 11.7x10³, 24.0x10³, 33.1x10⁷t.SO₂的最大排放源是电力供热;NO_x和BC的最大排放源是柴油车;CO的最大排放源是钢铁行业;VOCs的最大排放源是焦化行业;NH₃的最大排放源是畜禽养殖;PM₁₀和PM_2.5的最大排放源是道路扬尘;OC的最大排放源是生物质炉灶.榆林、西安和渭南是主要的SO₂和PM₁₀排放城市;榆林、西安和韩城是主要的PM_2.5排放城市;西安、榆林和咸阳是主要的NO_x排放城市;西安、榆林和延安是主要的VOCs排放城市;韩城、榆林和西安是主要的CO排放城市;榆林、渭南和宝鸡是主要的NH₃排放城市;榆林、西安和咸阳是主要的BC排放城市;榆林、西安和渭南是主要的OC排放城市.在此基础上分析了大气污染物和CO₂减排措施的减污降碳效应,发现民用能源清洁化、电厂清洁能源发电以及燃煤锅炉整治措施均有减污降碳效应,且电厂清洁能源发电的减污降碳协同效应最高.

Abstract

Based on the environmental statistics data and departmental survey data of Shaanxi Province in 2022, the emission inventory of atmospheric pollutants and CO₂ of Shaanxi Province in 2022 was established by a combination method of bottom-up and top-down. The results indicate that the total emissions of SO₂, NO_x, CO, VOCs, NH₃, PM₁₀, PM_2.5, BC, OC and CO₂ were 64.0x10³, 31.2x10⁴, 19.3x10⁵, 21.5x10⁴, 34.0x10⁴, 67.9x10⁴, 20.8x10⁴, 11.7x10³, 24.0x10³, 33.1x10⁷ tons, respectively. The primary source of SO₂ was electricity generation and heating supply; the primary source of NO_x and BC was diesel vehicles; the primary source of CO was the iron and steel industry; the primary source of VOCs was the coking industry; the primary source of NH₃ was livestock and poultry farming; the primary source of PM₁₀ and PM_2.5 was the road dust; and the primary source of OC was biomass stoves. Yulin, Xi’an and Weinan were the major cities with SO₂ and PM₁₀ emissions; Yulin, Xi’an and Hancheng were the major cities with PM_2.5 emissions; Xi’an, Yulin and Xianyang were the major cities with NO_x emissions; Xi’an, Yulin and Yan’an were the major cities with VOCs emissions; Hancheng, Yulin and Xi’an were the major cities with CO emissions; Yulin, Weinan and Baoji were the major cities with NH₃ emissions; Yulin, Xi’an and Xianyang were the major cities with BC emissions; Yulin, Xi’an and Weinan were the major cities with OC emissions. On this basis, the pollution and carbon reduction effects of air pollutants and CO₂ emission reduction measures were analyzed, and it was found that the cleanification of civil energy, the electricity generation of cleaner power energyin power plants and the renovation of coal-fired boilers all have pollution and carbon reduction effects,while the electricity generation of cleaner power energyin power plants have the highest synergistic effect.
