摘    要:根据长三角地区的实际情况,对该地区两省一市的秸秆焚烧PM2.5排放量状况进行估算.通过长三角地区2002年-2012年主要农作物产量、草谷比、焚烧比例和PM2.5排放因子,估算了该地区内秸秆焚烧量,同时对由秸秆焚烧引起的PM2.5排放量进行了估算,并进行了分析.结果表明:长三角地区2002年-2012年秸秆焚烧量最高的为农业发达的江苏省,高峰都集中在每年的10月份前后,由秸秆焚烧引起的PM2.5排放量呈逐年上升趋势,2012年达到55 218.96 t,其中江苏省每年的PM2.5排放量占到该地区的75%以上,2012年占到80%.研究结果将为制定该地区污染控制政策,改善区域环境空气质量提供科学理论依据.

关 键 词:长三角地区  秸秆焚烧  PM2.5排放量  草谷比  排放因子

Abstract:According to the actual situation of Yangtze River Delta Region,this study estimated the straw burning PM2.5 emission in two provinces and one city in the region.Through analysis on the main crops yields,grass valley ratio,burning rate and PM2.5 emissions factors of Yangtze River Delta Region from 2002 to 2012,it estimated the amount in the straw burning,at the same time caused by straw burning PM2.5 emissions estimates,and are analyzed.The results show that the Yangtze River Delta Region with the highest amount of straw burning from 2002 to 2012 for agriculture developed in Jiangsu province,the peak is concentrated in October each year,caused by straw buming PM2.5 emissions were rising trend year by year,in 2012 to 55218.96 t,which in Jiangsu province of PM2.5 emissions accounted for more than 75% of the region every year,accounted for 80% in 2012.The research results will provide pollution control policies,and provide scientific theoretical basis for improving the regional environmental air quality in the Yangtze River Delta Region.
Keywords:Yangtze River Delta Region  straw burning  PM2 5 emissions  grass valley ratio  emission factor
