摘　　要：本文为弄清重庆市主城区天然源的VOCs排放情况,基于遥感图像解译的土地利用现状和植被资料,利用实际观测的气象数据,在国外及其他城市等研究成果的基础上,测算了重庆市主城区2010年天然源VOCs排放量。结果表明,重庆市主城区天然源VOCs2010年排放总量为2.93万吨,其中异戊二烯0.57万吨(19.5%),单萜烯1.05万吨(35.7%)。VOCs排放的空间分布与土地利用和植被分布密切相关,且具有一定的季节变化规律。In order to get a clear picture of the emission of VOCs from natural sources in urban Chongqing , the emission there in 2010was calculated based on the observed meteorological data and remote-sensing image interpretation of land use and vegetation.The result showed that the annual total emission of biogenic VOCs from natural sources in urban Chongqing was about 29 , 300tin which isoprene accounted for 5 , 700t （19.5） and monoterpenes accounted for 10 , 500t （ 35.7% ） .The biogenic VOC emission had strong seasonal characteristics and its spatial distribution mainly depended on land use and vegetation types.
