摘要:

北京市农村地区煤炭消费严重影响区域空气质量。为改善空气质量,减少农村地区燃煤污染,北京市开展了以"煤改电"工程为代表的农村地区"减煤换煤、清洁空气"行动。为科学评估"煤改电"工程对区域大气环境质量的改善作用,研究选择门头沟区王平镇辖区内的东马各庄村和西石古岩村分别作为实施"煤改电"工程和未实施"煤改电"工程的典型区域,对比PM2.5、PM10、SO2及NO2等大气污染物浓度的差异,分析"煤改电"工程的大气污染物减排效果。结果表明,实施了"煤改电"工程的东马各庄村PM2.5、PM10、SO2和NO2质量浓度分别比未实施"煤改电"工程的西石古岩村低44.90%、24.75%、20.41%和26.67%;PM2.5、PM10、SO2和NO2的采暖季质量浓度分别是非采暖季的1.4、1.6、1.8和1.4倍。"煤改电"工程能够有效改善区域空气质量,尤其是在降低细颗粒物浓度方面具有较好的环境效益。建议未来加强对农村地区煤炭消费的监督管理,在积极巩固"煤改电"工程现有成果的基础上,加强政府政策引导,稳步推进"煤改电"工程实施规模。

Abstract:

Coal consumption in the rural areas of Beijing severely affects air quality of the region. The government has unfolded a movement entitled "Reducing Coal Consumption and Replacing Coal to Clean the Air", with the project of "Replacing Coal with Electricity" as representative in the rural areas of Beijing in an attempt to clean the air and reduce the pollution of smoke from coal burning. For scientific evaluation of effects of the project on regional air environmental quality, Dongmagezhuang Village and Xishiguyan Village in Wangping Town of Mentougou District were picked as two cases for study, one representing areas before unfolding of the project and the other representing areas after implementation of the project. Comparison was made between the two, in concentration of pollutants in the air, such as PM2.5、PM10、SO2 and NO2 for analysis of effects of the project reducing pollutant emission into the atmosphere. Results show that Dongmagezhuang Village was 44.90%, 24.75%, 20.41% and 26.67% lower respectively, than Xishiguyan Village in concentration of PM2.5, PM10, SO2 and NO2, and mass concentration of PM2.5, PM10, SO2 and NO2, in the heating season was 1.4, 1.6, 1.8 and 1.4 times as high as their respective one in the non-heating season. All the findings in the study demonstrate that the project improved the regional air quality, generating better environmental benefits, like lowering PM2.5 concentration in the air. It is, therefore, suggested that supervisory management of coal consumption in the rural areas should be strengthened in the future. And in addition to the consolidation of the beneficial effects of the project, more efforts should be devoted to intensification of government guidance using policies and steady extrapolation of the project in scale.
