摘要
以2013年为基准,采用排放系数法对成都市区域范围内工业源的VOC排放进行了核算,利用GIS工具构建成都市1 km×1 km网格化排放清单,分析了VOCs的空间分布特征.研究结果表明:2013年成都市工业源VOC排放总量为(5.77±3.35)×10~4t,其中溶剂使用源排放(3.09±4.93)×10~4t,工艺过程源排放(2.35±3.82)×10~4t,化石燃料燃烧源排放(0.21±0.61)×10~4t,生物质燃烧源排放(0.12±0.48)×10~4t.从工业源VOC排放的空间分布特征上看,都江堰、郫县、温江和崇州是最主要的贡献区县,涉及的排污企业类型主要包括钢铁、化工和水泥行业.
Based on the collected activity data and emissions factor for key VOC related industries in Chengdu City,a 2013-based 1 km×1 km grid cellbased VOC emissions inventory was developed by using geographic information system( GIS). The total VOC emissions from the key industries in 2013 was( 5.77±3.35) ×10^4 t,in which the emissions from the industries of solvent use,manufacturing process,fossil fuel combustion,biomass burning was( 3.09±4.93) ×10^4 t,( 2.35±3.82) ×10^4 t,( 0.21±0.61) ×10^4 t,( 0.12±0.48) ×10^4 t,respectively. In terms of the spatial distribution characteristics,the VOC emissions were mostly sourced from the districts of Dujiangyan,Pixian,Wenjiang and Chongzhou,whilst the corresponding industrial sources were steel,cement and chemical engineering.
