【摘要】：利用2015年8月1.5m級高分辨率遙感影像,對北京市平原區(qū)居住平房類型、面積和分布進行遙感監(jiān)測,獲取居住平房斑塊,并利用平房采暖面積調(diào)查、燃煤量現(xiàn)場抽樣調(diào)查等技術(shù)手段,估算了北京市平原區(qū)主要區(qū)居住平房冬季燃煤總量,同時結(jié)合相關(guān)文獻調(diào)研的無煙煤排放因子,測算北京平原區(qū)主要區(qū)平房燃煤PM、SO_2、CO、NO_x、黑碳(BC)和有機碳(OC)的排放量,為北京市原煤散燒管控及大氣污染防治提供基礎(chǔ)數(shù)據(jù).結(jié)果表明:北京市平原通州區(qū)平房燃煤量最大,達到97.4萬t,其次是順義和大興區(qū),均超過60萬t,昌平區(qū)和房山區(qū)則接近50萬t.從空間分布來看,燃煤散燒量由西北向東南呈現(xiàn)增加趨勢,燃煤量主要集中在城市發(fā)展新區(qū),壓減燃煤的工作重點仍集中在六環(huán)內(nèi)外的區(qū),但城市拓展區(qū)中朝陽和海淀山后區(qū)域均是散煤控制的重點區(qū)域,應(yīng)引起相關(guān)部門的重視.2015年北京市平原區(qū)居住平房燃煤消耗中,各區(qū)居住平房燃煤所產(chǎn)生的大氣污染物排污量差別明顯,其中通州區(qū)的SO_2和NO_x排放量最高,分別為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.
