辽宁省1980—2003年氮氧化物排放清单初步研究

Preliminary Study on Nitrogen Oxides Emission Inventory of Liaoning Province from 1980 to 2003

根据能源消费历史状况和氮氧化物（NOx）排放因子，分别对辽宁省20多年（1980-2003年）来的NOx排放总量以及不同燃料类型和行业的NOx排放量进行了估算．结果表明：尽管个别年份存在一些波动，但NOx排放总量总体上仍呈增长的趋势，年均增长率为4．30％．2003年辽宁省NOx排放总量达108×10^4t．NOx排放总量增长趋势与能源消费总量的增长趋势基本吻合，煤炭消耗是大气中NOx排放的主要来源，占总量的65％以上，最大排放量为2003年的10．17×10^4t．绝大部分NOx排放来自能源加工转换、工业和交通运输业，三者约占总量的90％，其中电力行业占28．10％～40．85％，预计在未来一段时间内电力行业仍将是辽宁省NOx排放的主要来源；交通运输部门NOx排放所占比例逐年上升，尤其在2000年后的增长趋势更为明显．

Based on emission factors and historical energy consumption statistics, NOx emission inventory in Liaoning Province from 1980 to 2003 was studied. Temporal variations were described and contributions from different sources （fuels, sectors） were estimated. The results showed that total amount of NOx emission increased by an annual growth rate of 4.30%, despite fluctuations in some years. In 2003, NOx emission amount was 108 × 10^4 t. The increase of NOx emission basically coincides with the increase of energy consumption, Contribution from coal consumption was the dominant source of NOx emission, which accounted for 65 % of the whole amounts, and the highest emission was in 2003, reaching 10.17 × 10^4 t. About 90% NOx was generated from energy transformation, industry and transportation sectors, and 28.10% ～ 40.85% of the total amount was generated from power industry, which will continue to be the dominant source of NOx emission in Liaoning Province in the future. The contribution from transportation sectors increased year by year and the trencl was more evident after the year 2000.
