Abstract：The GloBEIS model was utilized to analyse regional biogenic VOCs(BVOC) emission inventory of the Pearl River Delta (PRD) in 2006, based on the use of observed meteorological data and the remote-sensing image interpretation of land use and vegetation. The annual total emission amount of biogenic VOCs in the PRD was about 296kt in which isoprene accouned for 73.0kt (24.7%), and monoterpenes for 102 kt (34.4%). The biogenic VOCs emission had strong seasonal characteristics with maximum emissions in summer which accounted for 40.5% of whole year emission, while the minimum occurred in winter which accounted for 11.1%. The spatial distribution of BVOC emission mainly depends on land use and vegetation types, mostly located in less urbanized region and dense forest area. The uncertainty sources of estimating PRD regional BVOCs emissions were discussed.
