　　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VOCs 2010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 emis-sion there in 2010 was 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 ,300t in which isoprene accounted for 5 ,700t (19 .5% ) and monoterpenes accoun-ted 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 .
