摘要
为了解居民生活散煤燃烧污染物的时间及空间排放特征,基于抽样调查和GIS技术建立了天津市2017年散煤燃烧源污染物排放1 km×1 km网格清单。研究表明:①散煤燃烧主要以烟煤散煤为主,散煤类型具有显著的空间差异特征,核心区域以无烟煤为主,环城区域和涉农区域主要以烟煤为主。②污染物排放量从核心区-环城区-涉农区呈现显著增长趋势,核心区污染物排放时间特征无显著变化;环城区与涉农区污染物排放存在显著变化特征,两个区域内的散煤燃烧污染物排放均集中在采暖期(达90%以上)。
A sampling survey was conducted to investigate the combustion of domestic bulk coal burning in Tianjin.The pollutant emission from domestic bulk coal burning of Tianjin was estimated combined with the localization emission factor,a 2016-based 1 km×1 km grid emission inventory of domestic bulk coal burning for Tianjin was developed by GIS technology.The results showed that:1.Bituminous coal is the main type of domestic bulk coal consumption in Tianjin.There was a significant spatial difference characteristic of domestic bulk coal consumption between the core area,the loop area and the agriculture related area.The type of domestic bulk coal burning in the core area was mainly the anthracite,bituminous coal was the main type of scattered coal burning in the loop area and the agriculture related area.2.The pollutant emission of domestic bulk coal burning from the core area-loop area-agriculture related area showed a significant growth trend.There was no significant change of temporal characteristics of pollutant emission in the core area,and there was a significant change of temporal characteristics of pollutant emission between the loop area and the agriculture related area,the pollutant emissions from domestic bulk coal burning were concentrated in the heating period in these two areas(up to 90 percent).
