摘要
盐基阳离子排放清单的建立 ,对于中国酸沉降控制有重要的意义。针对电力、建材和钢铁工业 ,基于颗粒物的排放量和化学组成 ,分别计算工业点源和工业面源的大气盐基阳离子排放量 ,并绘制中国盐基阳离子排放强度分布图。结果表明 ,中国 2 0 0 0年工业源排放盐基阳离子总量为 4 17.0万 t,其中工业面源占 81.0 %。中国工业源盐基阳离子排放强度分布呈现东部高西部低的格局 ,最大值出现在河南省 ,达到了 2 12 .8kmol.km- 2 .a- 1。
A thorough inventory of base cation emissions in China is needed to develop programs for acid deposition control. The atmospheric emissions of base cations from each major industrial source (including point and area sources, especially from the power, cement, and steel industries) were estimated based on emission rates and the chemical composition of the particulate matter. A map of emission intensities was also compiled. The results show that the total industrial emissions of base cations in China is about 4.170 million tons in 2000, with 81.0% from area sources. In general, the base cation emissions are lower in western China and higher in the east. The maximum rate is 212.8 kmol·km^-2·a^-1 in Henan Province.
