摘　　要：基于常规可获取的能源、交通、人口等统计资料,利用排放因子法,研究了2012年长江三角洲（以下简称＂长三角＂）地区火电、一般工业、交通、居民燃煤及生物质燃烧的黑碳排放量及其空间分布特征.结果表明：该地区的黑碳排放总量为4.89×10^4 t·a^-1,其中火电、一般工业、交通、居民燃煤和生物质燃烧分别占5.0%、54.8%、17.9%、0.5%和21.8%.苏州、上海、无锡、南通和杭州五个城市的排放量最高,总贡献率为53.0%.煤炭燃烧是黑碳排放最主要的来源（贡献率为58.4%）,其次是生物质.该地区黑碳的平均排放强度为0.44t·km^-2·a^-1.本文还基于GIS（Geographic Information System）给出了长三角地区黑碳排放强度的网格化分布,多数城市高值区介于2.0～5.0t·km^-2·a^-1.Based on conventional statistical data on energy consumption,transportation and population,black carbon emissions from power plant,general industry,transportation,residential coal-burning and biomass burning in the Yangtze River Delta（YRD）in 2012 were estimated by using the emission factor method.Results show that total amount of black carbon emissions in the YRD was 4.89×10^4 t·a^-1.Power plants,general industry,transportation,residential coal-burning and biomass burning contributed 5.0%、54.8%、17.9%、0.5% and 21.8%,respectively.Black carbon emissions from Suzhou,Shanghai,Wuxi,Nantong and Hangzhou,among which were the highest,accounted for53.0% of the total amount.Coal burning was the most important source for emission（58.4%）,and the second was biomass.The mean emission intensity in study area was 0.44t·km^-2·a^-1.In addition,gridded distribution of black carbon emission intensity based on GIS with high values between 2.0and 5.0t·km^-2·a^-1in most urban areas was obtained.
