摘要
估算了珠江三角洲地区2006年大气面源污染物的排放清单,并利用2006年珠江三角洲人口分布栅格数据作为代用空间分配权重因子,建立了该地区大气面源3km×3km的SO2、NOx、PM10和VOC网格化排放清单.结果表明,2006年珠江三角洲大气面源排放的SO2为1.12×105t,NOx为5.25×104t,PM10为1.6×105t,VOC为3.14×105t.SO2、NOx和PM10排放量较大的区域集中在广州市区、佛山、东莞和中山,而VOC排放量较大的区域位于广州市区、东莞和深圳.
The 2006 Pearl River Delta （PRD） area source emission inventories of air pollutant and 3km×3km grid cell-based emission inventories of SO2, NOx, PM10, and VOC were established using the 2006 gridded data of population distributions as spatial surrogates. The total emissions of SO2, NOx, PM10, and VOC from area sources of PRD were 1.12×10^5, 5.25×10^4, 1.6×10^5, 3.14×10^5t, respectively, for the year of 2006. The large amount of emissions of SO2, NOx and PM10 were concentrated on the cities of Guangzhou, Foshan, Dongguan and Zhongshan while VOC emissions were mostly distributed in Guangzhou, Dongguan and Shenzhen.
