煤炭消费结构对中国大气污染的影响及对策建议

Impacts of coal consumption structure on China air pollution and countermeasures

通过分析我国及各省的历史煤炭消费结构特征,以燃煤污染物排放占比和污染物排放强度为衡量指标,研究2001-2012年电力耗煤和非电力耗煤对大气污染物的影响程度,结果表明,非电力耗煤对污染物排放的贡献率以及污染物排放强度均大于电力耗煤,烟粉尘的燃煤排放差距尤为明显。因此,提出调整煤炭消费结构,控制非电力耗煤占比等对策建议,从而促进实现煤炭的合理消费与大气污染物的有效控制。

Through analyzing China＇s and ture, with taking the proportion of coal-fired each province＇s historical coal consumption strucemissions and pollutants emission intensity as the measurement index, to study the impacts of coal consumption of power industry and non-power industry on air pollutants respectively from 2001 to 2012. The results show that, the contribution rate of non-power industry coal consumption to pollutants emissions and its emission intensity are both larger than the power industry coal consumption＇s, while the coal-fired smoke dust emissions gap is particularly evident. Therefore, the countermeasures to adiust coal consumption structure, and control the proportion of non-power industry coal consumption and other suggestions are proposed, so as to promote the realization of reasonable coal consumption and effective control of air pollutants.
