Based on Sichuan province environmental statistical survey data and other relevant activity data, volatile organic compounds (VOCs) emissions from typical anthropogenic sources in Sichuan province were calculated for the year of 2011 by applying the emission factor method. Besides, ozone and secondary organic aerosol formation potentials of these typical anthropogenic sources were discussed. The total VOC emission from these sources was about 482 kt in Sichuan province, biomass burning, solvent utilization, industrial processes, storage and distribution of fuel, and fossil fuel combustion contributed 174 kt, 153 kt, 121 kt, 21 kt and 13 kt, respectively; architecture wall painting, furniture coating, wood decoration painting and artificial board were the major emission sectors of the solvent utilization; while for the industrial processes, 19.4% of VOCs emission was from the wine industry. Chengdu was the largest contributor compared to the other cities in Sichuan, whose VOCs emission from these typical anthropogenic sources in 2011 was 112 kt. OFP of these sources was 1,930 kt altogether. Solvent utilization contributed 50.5% of the total SOA formation potentials, biomass burning and industrial processes both contributed about 23% , with storage and distribution of fuel and fossil fuel combustion accounting for 1% and 1.4%, respectively.
基于四川省环境统计调查数据及其他相关活动数据，采用排放因子法计算了2011年四川省典型人为源挥发性有机物（VOCs）排放量。此外，还探讨了这些典型人为源的臭氧和二次有机气溶胶生成潜势。四川省这些源的VOCs排放总量约为48.2万吨，生物质燃烧、溶剂使用、工业过程、燃料储存与运输以及化石燃料燃烧的排放量分别为17.4万吨、15.3万吨、12.1万吨、2.1万吨和1.3万吨；溶剂使用的主要排放行业为建筑墙面涂装、家具涂饰、木质装饰涂饰和人造板；而工业过程中，19.4%的VOCs排放来自酿酒行业。与四川省其他城市相比，成都的排放量最大，2011年其这些典型人为源的VOCs排放量为11.2万吨。这些源的臭氧生成潜势总量为1930万吨。溶剂使用对二次有机气溶胶生成潜势总量的贡献为50.5%，生物质燃烧和工业过程的贡献均约为23%，燃料储存与运输和化石燃料燃烧的贡献分别为1%和1.4%。
