摘要
根据我国燃料消费、燃料的含硫量和硫与氮氧化物排放因子，计算我国各地区ＳＯ_２和ＮＯ_Ｘ排放强度地理分布。结果指出，我国原煤含硫量为１．１２％。１９９０年全国ＳＯ_２和ＮＯ_Ｘ的排放量分别为１７５１．８万ｔ和８４２．２万ｔ，排放强度最大的地区是中东部地区，即辽宁、河北、山东、山西和浙江。这些地区平均排放强度大于７ｔ／ｋｍ￣２·ａ。还估算了全国１９５０～１９９０年ＳＯ_２和ＮＯ_Ｘ历年的排放量。
The geographycal distribution of SO_2 and NO_X emission intensities in China have been calculated for 1988 and 1990 based on the total fuel consumption,sulphur contents in fuels and emission factors for used fuels in various areas.Results show that SO_2 and NO_X emissions in 1990 are 17518kt and 8422kt respectively and the heigh emission intensity areas are concentrated in middle East China. The historical emission trends are also given in this calculation.
