摘　　要：基于2007年夏季秸秆焚烧卫星遥感监测资料,结合粮食产量、谷草比、排放因子等,估算了河南省秸秆焚烧各污染物的排放量。结果表明,2007年夏季河南省秸秆焚烧共排放:PM2.5 30 433.9 t、SO2 1 586.2 t、NOx 12.2 t、NH3 76.1 t、CH4 39.6 t、VOC 82.2 t、CO477.8 t、CO2 2 799.9 t。秸秆焚烧污染物排放量空间分布受小麦种植面积影响较大,中东部多于西部,其中周口、驻马店和南阳排放量最多;夏季秸秆焚烧较为集中,PM2.5的排放多集中在5月下旬和6月上旬,且与郑州市PM2.5日均浓度有较好的相关性。Emission of various pollutants from straw burning in the summer of 2007 was estimated according to remote sensing data combined with data of winter wheat yields,grain-straw ratio and emission factors,etc.The data showed that emissions of PM2.5 and SO2 were estimated at 30 433.9 t and 1 586.2 t,respectively.Meanwhile,other pollutants included NOx 12.2 t,NH3 76.1 t,CH4 39.6 t,VOC 82.2 t,CO 477.8 t,and CO2 2 799.9 t.Pollutant emission was higher in the central and eastern regions of Henan than that in the western,especially in Zhoukou,Zhu-madian and Nanyang.This result indicated a strong correlation between polutant emission and distribution of winter wheat planting area.As straw burning usually occurs in summer,PM2.5 emission was mainly emitted in late May and early June,which has a good correlation with av-erage daily PM2.5 concentration in Zhengzhou.
