摘要： 为了厘清海南省生物质燃烧源污染状况，本文调查了海南省2019年生物质燃烧源活动水平数据，采用排放因子法，建立了海南省2019年生物质燃烧7种污染物的排放清单，并进行时空配分和不确定分析。结果表明：2019年海南省生物质燃烧源排放的CO、CO₂、SO₂、NO_X、NH₃、CH₄和PM_2.5分别为17779.77、587732.18、340.87、1208.31、308.69、5674.55和4946.24 t。其中，稻谷秸秆露天焚烧对CO、CO₂、SO₂、NO_X、NH₃、CH₄和PM_2.5排放贡献率最高，而花生和甘蔗秸秆露天燃烧的CH₄排放贡献率最高。海南省生物质燃烧源大气污染物排放地区分布不均衡，海口市是主要污染区域。海南省生物质燃烧源大气污染物月份排放时间也不均衡，排放多集中在每年的3、4、7和10月，多集中在每日的3:00—6:00、11:00—15:00和17:00—19:00。不确定性分析表明，森林火灾的CO₂和NH₃排放的不确定度最高，分别为-29.5%～28.5%和-27.7%～29.6%；秸秆露天焚烧的CH₄排放不确定度最低，仅为-15.5%～12.5%。

Abstract: To clarify the pollution situation of biomass combustion sources in Hainan Province, we investigated the activity level data of biomass combustion sources in Hainan Province in 2019, established the emission inventory of seven pollutants from biomass combustion using the emission factor method, and analyzed spatiotemporal distribution and uncertainty of the emission inventory. The results showed that the emissions of CO, CO₂, SO₂, NO_X, NH₃, CH₄ and PM_2.5 from biomass combustion sources in Hainan Province in 2019 were 17779.77, 587732.18, 340.87, 1208.31, 308.69, 5674.55, and 4946.24 t, respectively. Open burning of rice straw had the highest contribution rate to CO, CO₂, SO₂, NO_X, NH₃, CH₄ and PM_2.5 emissions, while open burning of peanut and sugarcane straw had the highest contribution rate to CH₄ emissions. The distribution of air pollutant emissions from biomass combustion sources in Hainan Province was uneven. Haikou was the main emission area of pollution. The emission of air pollutants from biomass combustion sources in Hainan Province was uneven at the temporal perspective, and most of the emissions were concentrated in March, April, July and October, and mostly concentrated in the daily period of 3:00-6:00, 11:00-15:00 and 17:00-19:00. The uncertainty of CO₂ and NH₃ emissions from forest fires was the highest, being -29.5% to 28.5% and -27.7% to 29.6%, respectively. The uncertainty of CH₄ emission from open burning of straw was the lowest, being -15.5% to 12.5%.
