【摘要】：利用2015年8月1.5m级高分辨率遥感影像,对北京市平原区居住平房类型、面积和分布进行遥感监测,获取居住平房斑块,并利用平房采暖面积调查、燃煤量现场抽样调查等技术手段,估算了北京市平原区主要区居住平房冬季燃煤总量,同时结合相关文献调研的无烟煤排放因子,测算北京平原区主要区平房燃煤PM、SO_2、CO、NO_x、黑碳(BC)和有机碳(OC)的排放量,为北京市原煤散烧管控及大气污染防治提供基础数据.结果表明:北京市平原通州区平房燃煤量最大,达到97.4万t,其次是顺义和大兴区,均超过60万t,昌平区和房山区则接近50万t.从空间分布来看,燃煤散烧量由西北向东南呈现增加趋势,燃煤量主要集中在城市发展新区,压减燃煤的工作重点仍集中在六环内外的区,但城市拓展区中朝阳和海淀山后区域均是散煤控制的重点区域,应引起相关部门的重视.2015年北京市平原区居住平房燃煤消耗中,各区居住平房燃煤所产生的大气污染物排污量差别明显,其中通州区的SO_2和NO_x排放量最高,分别为3534.4,2514.0t.
[Abstract]:Based on the 1.5m high resolution remote sensing image of August 2015, the type, area and distribution of residence bungalow in Beijing plain area were monitored by remote sensing, and the patch of residence house was obtained, and the area of house heating was investigated.By means of spot sampling investigation and other technical means, the total amount of coal burning in winter for residential houses in the main areas of Beijing Plain District was estimated, and the anthracite emission factor combined with the related literature investigation was also used to estimate the total amount of coal burning in winter.The emissions of coal-fired PMSO2 / COCX, black carbon (BCC) and organic carbon (OCC) were measured in the main areas of Beijing plain, which provided basic data for the control of raw coal and the prevention and control of air pollution.The results show that the coal burning capacity in Tongzhou district of Beijing Plain is the largest, reaching 974000 t, followed by Shunyi and Daxing districts, each exceeding 600000 ts. Changping District and Fangshan District are close to 500000 t.From the spatial distribution point of view, the amount of pulverized coal increased from the northwest to the southeast. The amount of coal burning was mainly concentrated in the new urban development areas, and the focus of the reduction of coal combustion was still concentrated in the areas inside and outside the sixth Ring Road.However, the Chaoyang area and the area behind Haidian Mountain in the urban development area are the key areas for the control of scattered coal, which should be attached importance to by the relevant departments. In 2015, the coal consumption of residential bungalows in the Beijing Plain area,The emission of air pollutants from coal burning in different areas is different, and the emission of SO_2 and NO_x in Tongzhou district is the highest, which is 3534.4t / 2514.0t respectively.
