为了解河南省秸秆露天焚烧大气污染物排放情况,根据2014年河南省的主要农作物产量、草谷比、焚烧比例和排放因子,采用排放因子法估算河南省秸秆焚烧大气污染物的排放量,建立河南省秸秆露天焚烧的污染物排放清单,并分析了大气污染物排放量的时空分布。结果表明:2014年河南省秸秆露天焚烧共排放:CO2 1 210.45万t、CO 51.74万t、CH4 3.27万t、NMVOCs 7.19万t、NH3 0.59万t、BC 0.42万t、OC 2.47万t、SO2 0.55万t、NOX 3.13万t、PM2.5 7.48万t。小麦和玉米是河南省露天焚烧排放大气污染物主要贡献源,其贡献率分别为38%~67%和17%~36%。大气污染物排放的高值区主要集中在驻马店、周口、南阳和商丘四个地市。大气污染物排放的高峰期集中在6月和10月,这两个月的各类污染物排放量对全年总排放量的分担率分别为37.1%~65.7%和11.3%~37%。 |

Open burning of agriculture straw residueis a common method to dispose waste after harvesting seasons in Henan Province.Based on the survey data, the air pollutant emission inventory of crop straw open burning in 2014 for Henan Province was established by using emission factor approach. Besides, the temporal and spatial distribution characteristics of air pollutant emissions were also presented in this paper. The results showed that the total emissions of CO2, CO, CH4, NMVOCs, NH3, BC, OC, SO2, NOX and PM2.5 from straw residues open burning in Henan Province were 1.210 45×107, 5.174×105, 3.27×104, 7.19×104, 5.9×103, 4.2×103, 2.47×104, 5.5×103,3.13×104 and 7.48×104 t in 2014.Wheat and maize were the main sources of air pollution in Henan Province, with the contribution rate 38%~67% and 17%~36%. Spatially, the cities of Zhumadian, Zhoukou, Nanyang and Shangqiu were the highest value areas of atmospheric pollutant emission in Henan Province. Temporally, the emissions were concentrated in June and October,with the contribution rate 37.1%~65.7% and 11.3%~37% respectively. The research results will provide scientific basis for improving the regional environmental air quality in Henan province. |
